Why support teams leave the AI they already have

I'm on eesel's support team, and I hear from a lot of teams who are halfway out of another AI tool. The reasons repeat. In eesel's own sales calls this year, two separate teams running Zendesk said they'd tried the native AI and found it expensive and inadequate. A Freshdesk team that tested Freddy AI said eesel's answers came out more precise. A B2B hardware company had to replace its AI because the vendor changed how it did business. None of them were unhappy with AI as an idea. They were unhappy with the specific tool sitting in their queue.

When I line those calls up against what support leads post publicly, the same four problems show up.

1. The bill is hard to predict. Per-resolution and per-interaction pricing both sound fair until you try to forecast them. One fintech ops lead told us a 3,000-interaction monthly allowance would have run out in about a day and a half at their volume, since every ticket meant several back-and-forth messages. That allowance was eesel's own old per-interaction plan, and it's a big part of why eesel now bills per ticket instead. Ticket-based plans have their own version of this:

G2

"The main frustration with Gorgias is the pricing model, which is based on ticket volume rather than a flat monthly fee. As our order volume grows and customer inquiries increase, the cost scales up quickly in ways that can be difficult to predict and budget for."

Mitchell O., G2, VP of Sales and Acquisition

2. Nobody agrees on what "resolved" means. If you pay per resolution, the vendor's definition of a resolution is your invoice. Zendesk now runs an LLM check on each conversation and only bills "Verified" resolutions (resolution tiers), which is a real improvement. Buyers still worry about the old failure mode:

Reddit

"who knows if the bot is just leaving the customer hanging and marking it as a resolution."

3. The handoff is where it falls apart. An AI that resolves 50% of tickets but fumbles the other 50% creates more work than it saves. One Gorgias user on Reddit put it bluntly: "I find that most of the responses have an error that I have to apologize for after the handoff" (r/ecommerce). Read up on AI escalation before you trust any vendor's handoff demo.

4. It only knows your help center. Most built-in agents learn from published articles, URLs and files. Your best answers usually live in resolved tickets and macros, and several tools on this list don't read either. That gap is why the knowledge base work never seems to end.

Decision tree for picking an AI customer support software alternative: if you won't keep your helpdesk, switch and use its built-in AI (Zendesk, Freshdesk, Gorgias, HubSpot, Help Scout, Salesforce); if you keep it and want a sales-led custom build, pick an AI-native platform (Ada, Decagon, Sierra); otherwise use AI that plugs into your helpdesk (eesel)
Decision tree for picking an AI customer support software alternative: if you won't keep your helpdesk, switch and use its built-in AI (Zendesk, Freshdesk, Gorgias, HubSpot, Help Scout, Salesforce); if you keep it and want a sales-led custom build, pick an AI-native platform (Ada, Decagon, Sierra); otherwise use AI that plugs into your helpdesk (eesel)

That decision tree is the whole post in one picture. The ten alternatives below fall into three groups: AI built into a helpdesk, AI-native platforms that sit in front of one, and AI that plugs into the helpdesk you already have.

How I compared these alternatives

I went through each vendor's own pricing page, help docs and trust center on October 12, 2026, and pulled user reviews from G2, Capterra, Reddit and Hacker News. For each tool I checked five things:

  • Which helpdesk it needs. Does it run on top of your current setup, or does it come with its own?
  • The billing unit. Per resolution, per session, per conversation, per action, or per ticket handled. They are not the same thing, and the difference shows up in your cost per resolution.
  • How you test it before go-live. Questions you write, simulated customers, or a replay of your own past tickets.
  • What it learns from. Help center only, or also past tickets and macros.
  • Security. SOC 2, ISO 27001, HIPAA and GDPR, from each vendor's own trust page.

I didn't count vendor-reported resolution rates as evidence, because every vendor counts them differently. If you want the full buying process rather than a shortlist, my earlier guide on how to choose one walks through it step by step.

AI customer support software alternatives compared

Prices are list prices for the AI part only, in USD, as published on October 12, 2026. "Billed if unresolved" means you pay for a conversation the AI touched but didn't close on its own.

Two things jump out. First, only one tool on the list replays your real past tickets and grades itself against what your team actually sent; everything else tests on questions you write or customers an AI invents. Second, three of the ten won't tell you a price until you've sat through a demo.

What each alternative would cost on your volume

A pricing grid doesn't tell you much when every vendor bills a different unit. So here's the same math done for you. Type your volume, pick how often the AI resolves a ticket on its own, and see the AI line item for every tool that publishes a price.

Plug in your own monthly volume and resolution rate to see where flat per-ticket pricing beats per-resolution pricing. List prices only, helpdesk seats excluded.

If you'd rather read it as a table, here's one scenario: 2,000 tickets and chats a month, with the AI resolving half of them (1,000) on its own.

ToolHow the AI part is billedAI cost at 2,000/mo, 50% resolved
eesel2,000-credit plan, 1 credit per ticket or chat$849
Zendesk AI agents1,000 verified resolutions x $1.50 committed$1,500, minus 5 to 15 included per agent
Freddy AI Agent2,000 sessions x $0.49$980 (500 free sessions once per account)
Gorgias AI Agent1,000 automated interactions x $0.90$900, plus your plan's ticket fees
Help Scout AI Answers1,000 resolutions x $0.75$750, Beacon chat widget
Agentforce, per conversation2,000 x $2$4,000
Agentforce, Flex Credits2,000 x 3 actions x $0.10$600, plus Data 360 credits
HubSpot Customer Agent1,000 resolutions x $0.50$500, minus 3,000 included credits on Pro (60 resolutions)
Ada, Decagon, SierraNot publishedQuote only

The honest takeaway: if your AI only resolves 20% of tickets, per-resolution pricing will usually beat a flat plan, and I'd tell you to stay on it. The flat plan starts winning once the AI is doing real work. At 50% resolved, eesel's 2,000-credit plan costs $849 while 1,000 Zendesk resolutions cost $1,500. Seats are a separate line on every helpdesk-native option, and eesel doesn't charge for them at all.

1. eesel

Best for: teams who like their helpdesk but not the AI that came with it.

eesel helpdesk simulation results for 20 resolved Zendesk tickets: 17 of 20 matched the team's reply quality, with results by theme and ranked fixes, as taken from the eesel docs
eesel helpdesk simulation results for 20 resolved Zendesk tickets: 17 of 20 matched the team's reply quality, with results by theme and ranked fixes, as taken from the eesel docs

eesel is where I work, so weigh this section accordingly. It's an AI teammate platform: you hire a ready-made teammate for a specific job, and for support that's the AI helpdesk teammate. It doesn't replace your helpdesk. It joins the queue you already run in Zendesk, Freshdesk, Gorgias, HubSpot, Help Scout, Front, Salesforce Service Cloud or Jira Service Management (see the integrations list), and works tickets there with your macros, tags and views intact.

That matters most when the thing you want to replace is the AI, not the helpdesk. You don't migrate tickets, retrain agents or rebuild triggers. You switch off the old bot and let a different one draft into the same queue.

What it does well

  • Learns from your past tickets. "On a Full connection. It reads your help center, macros and past tickets so it knows how your team answers before it touches anything" (eesel docs). A Quick start connection reads only the public help center.
  • Tests on your real history. The Simulation skill "replays your past tickets and scores its answers against what your team actually sent" (docs). In the run above, 17 of 20 replies matched, two tickets were correctly escalated to a human, and one was a partial miss.
  • Starts supervised. Every action is set to Auto, Needs approval or Disabled, and the docs recommend keeping "refunds, cancellations and anything that costs money behind an approval" (Actions and Approvals).
  • Runs from a terminal too. The eesel CLI drives the same teammate and workspace as the dashboard: eesel integrations connect zendesk, then eesel automations to wire up what it does on new tickets, and eesel approvals to clear anything waiting on a human. Coding agents like Claude Code, Codex and Cursor can run those same commands, which is handy if your ops team scripts everything. More on that in the AI agent CLI post.

Pricing

From eesel pricing: a ticket or chat the agent works on is 1 credit, "however long". There's no seat fee, and tickets you tell it to leave alone (spam, auto-replies) don't count.

Credits per monthPrice per month
100 (Free)$0, no card
500$299
1,000$499
2,000$849
3,000$1,149
4,000$1,449
5,000$1,749
More than 5,000Custom

Plans step up every 500 credits in between. Overage is off by default; turn it on and extra credits are $0.80 each up to a cap you set. Enterprise adds SSO, HIPAA with a signed BAA and custom data residency.

Pros and cons

Pros:

  • Keeps your helpdesk, history and workflows in place.
  • Pre-launch replay against your own resolved tickets.
  • Flat monthly price with unlimited seats, easy to forecast.

Cons:

  • You pay per ticket handled, not per resolution, so a ticket the AI works but hands to a human still uses a credit.
  • SOC 2 Type II is still in progress; the observation period runs to December 31, 2026 (security page).
  • HIPAA is Enterprise only. Earlier this year, a US healthcare team on Zendesk walked away from eesel because a BAA wasn't available yet.

Verdict

Pick eesel if your helpdesk is fine and the AI is the problem. Skip it if you need a SOC 2 report in hand this quarter, or if your AI resolves so few tickets that paying per resolution is cheaper (the calculator above will show you).

2. Zendesk AI agents

Best for: teams staying on Zendesk who want the AI inside the same contract.

If you're unhappy with Zendesk's AI, it's worth checking whether you're unhappy with the current version. Zendesk removed the Essential vs Advanced split this year, so agentic reasoning, procedures and "external API integrations" are now "included across Zendesk Suite and Support plans" (Zendesk announcement). Essential agents go away entirely on December 10, 2026. For a deeper walk-through, see my team's Zendesk AI review.

What it does well

  • Native everything. Messaging, email and voice, with escalations landing in the same agent workspace.
  • Fairer billing than before. Only "Verified" resolutions draw down your allowance, after an LLM checks that the customer's request "was satisfactorily resolved" (resolution tiers). Assisted escalations don't count.
  • No-code actions. An integration builder and action flows for order lookups and account changes (About actions).

Pricing

From the Zendesk pricing page: $1.50 per automated resolution on a commitment, $2.00 pay-as-you-go. Plans include 5 (Team), 10 (Professional) or 15 (Enterprise) per agent per month, capped at 10,000 a year. Seats start at $19 per agent per month on Support Team (annual). The full breakdown is in our Zendesk AI pricing guide.

Pros and cons

Pros:

  • One vendor, one login, one bill.
  • You don't pay for escalated conversations.
  • 80+ languages, per Zendesk.

Cons:

  • The conversation simulator is early access, messaging-only, and built for "fictional data", so you test on scenarios you write, not your ticket history.
  • Past tickets aren't listed as a knowledge source.
  • Forecasting is still on you:
Reddit

"Up to this day, Zendesk has not yet shared any forecasting tool for AR. Not sure if anyone us techy on this thread, but how hard is developing that mechanism really? So hard to plan ahead without a forecast :("

Verdict

Stay with Zendesk's AI if your resolution rate is low and you like a single vendor. If you're leaving because the answers are weak, look at the Zendesk AI alternatives that run on top of Zendesk instead of replacing it.

3. Freshdesk Freddy AI Agent

Best for: Freshdesk Omni teams who want chat and email AI without another vendor.

Freddy AI Agent lives in Freshworks' AI Agent Studio and runs on current Freshdesk Omni plans (Growth, Pro, Enterprise). The email agent "works directly in the Freshdesk ticket inbox", which is a nice touch if most of your volume is email (Email AI Agent setup). Our Freddy AI guide covers the wider Freddy family.

What it does well

  • Bulk testing. Up to 100 test queries per run on chat, or 50 AI-generated sample queries from your knowledge (Test and optimize).
  • Real tickets as test input on email. The email Evaluate tool can "Import tickets to use solved historical tickets", up to 50 per run.
  • Workflow library. Templates for order status and refunds, plus an API block for your own systems.

Pricing

From the Freshdesk Omni pricing page: seats from $29 per agent per month (annual), the first 500 Freddy AI Agent sessions free once per account, then "$49/100 sessions". A session is everything inside 24 hours on chat or a 72-hour window on email, resolved or not. Copilot for human agents is a separate $29 per agent per month. More in the Freddy AI pricing breakdown.

Pros and cons

Pros:

  • Cheap per-session rate ($0.49) with no resolution argument to have.
  • Email agent works inside the existing ticket inbox.
  • ISO 27001 and SOC 2 Type 2 on the trust center.

Cons:

  • You pay for sessions that end in a handoff.
  • Imported tickets are graded Answered or Unanswered, not compared with the reply your agent actually sent.
  • Only on Omni plans; "Not available in previous plans."

Verdict

Freddy is a sensible pick if you're already on Freshdesk Omni and most of your volume is simple. If you're on an older Freshdesk plan or want the AI to learn from how your team writes, compare the Freddy alternatives that plug into Freshdesk.

4. Gorgias AI Agent

Best for: Shopify stores that want the AI to cancel orders and edit addresses on its own.

Gorgias is the ecommerce helpdesk, and its AI Agent leans hard into that. Connect Shopify and it gets actions like Cancel order, Edit shipping address and Reship order for free with no extra setup (Gorgias docs). It also hands over automatically on anger, legal threats or a request for a human, and you can mark whole intents as "Handover" on the AI coverage page. See the Gorgias AI overview for the rest.

What it does well

  • Order actions out of the box for Shopify, plus Recharge, Loop and shipping apps.
  • Built-in handover rules that can't be switched off for sensitive topics.
  • Playground testing against a fake or real customer profile, including rerunning an existing ticket after you change a setting (test conversations).

Pricing

From Gorgias pricing and its billing docs: you pay a ticket fee on every ticket the helpdesk replies to, plus an automation fee of $1.00 (Starter), $0.90 (Basic and Pro) or $0.85 (Advanced) when "the customer does not require the involvement of a human agent within 72 hours". Bundles with AI run from $40 a month (Starter, 50 tickets) to $1,430 (Advanced, 5,000 tickets). Details in Gorgias AI Agent pricing.

Pros and cons

Pros:

  • Strongest native Shopify actions on this list.
  • Automation fee only applies when no human steps in for 72 hours.
  • Free trial with no card.

Cons:

  • Full functionality is Shopify-only, one AI Agent per store.
  • "Does AI Agent use my macros? No," per Gorgias's own docs, and past tickets aren't a knowledge source.
  • Testing is one conversation at a time, and test actions can touch real orders unless you use a fake profile.
G2

"The AI Agent is powerful, but the training and knowledge base configuration can be complex. There are a lot of rule nuances and automation layers that require careful setup, and the learning curve can be steep when optimizing for more advanced use cases."

Hannah S., G2, Operations Specialist, Mid-Market

Verdict

If you run Shopify on Gorgias and want refunds and cancellations handled end to end, it's hard to beat. If your store isn't on Shopify, or you want the AI to write like your agents do, look at Gorgias AI Agent alternatives that read your Gorgias history.

5. Salesforce Agentforce

Best for: service orgs that already run on Salesforce and have an admin to spare.

Salesforce case "Help With a Return" with an Agentforce chat about a backpack return and a Service Rep Assistant asking to confirm the refund, as taken from Salesforce

Agentforce is Salesforce's agent platform, and the Service agent is the customer-facing part. It lives inside Salesforce, needs Enterprise, Performance, Unlimited or Developer Edition, and grounds answers through Data Libraries, which require Data 360 and "consume Data 360 credits" (Salesforce Help). If that sentence felt like a lot, that's the honest preview of the setup. Our Agentforce customer service post goes deeper.

What it does well

  • Two billing models you can pick between, per conversation or per action.
  • A real testing center. Generate test cases from your agent's actions, build Q&A tests from your knowledge, or upload up to 1,000 cases by CSV (Testing Center considerations). As of Summer '26, Testing Center runs don't consume Flex Credits.
  • Enterprise compliance. SOC 2, ISO 27001:2022 and ISO 42001, and the Service Agent is on Salesforce's HIPAA covered services list with a BAA (Salesforce compliance).

Pricing

From the Agentforce pricing page: $2 per conversation, or Flex Credits at $500 per 100,000 credits, where a standard action is 20 credits ($0.10). You can't mix the two in one org. Salesforce's own chart shows why the choice matters:

Salesforce chart showing Flex Credits scaling with Agentforce actions: a 1-action knowledge answer costs $0.10, a 3-action case status check $0.30 and a 6-action field service booking $0.60, each against $2 per conversation, as taken from Salesforce

On top of that sit Service Cloud seats ($195 or $395 per user per month for the tiers where Agentforce for Service is an add-on) and Data 360 credits. Full math in our Agentforce pricing guide.

Pros and cons

Pros:

  • Per-action Flex Credits can be far cheaper than $2 a conversation for simple flows.
  • Structured, bulk testing with CSV upload.
  • Strongest compliance paperwork on this list.

Cons:

  • Salesforce-only, with Data 360 as a dependency for knowledge answers.
  • Testing is generated or written cases; the docs describe no replay of real past cases.
  • Needs a confident admin:
G2

"What I dislike most is that Agentforce can require significant setup, testing, and ongoing optimization to ensure the responses and actions are accurate. The quality of the experience also depends heavily on how well the underlying Salesforce data is structured and maintained."

Katherine D., G2, Mid-Market

Verdict

Pick Agentforce if Salesforce is your system of record and you have admin capacity. If you want AI on Service Cloud cases without Data 360 and a build project, the Agentforce alternatives list is the better starting point.

6. HubSpot Customer Agent

Best for: teams running support in HubSpot's help desk who want the AI priced per resolution.

HubSpot Create customer agent window with agent name, personality, existing knowledge and website sync settings next to a live agent chat preview, as taken from HubSpot's knowledge base

HubSpot's Customer Agent (formerly Breeze Customer Agent, now part of Agent Hub) answers on chat, email, forms, WhatsApp, Facebook Messenger and phone (beta). Every one of those channels has to connect to a HubSpot inbox or help desk workspace, so in practice it needs HubSpot as your helpdesk (Understand the customer agent). It also halved its price in April. See our Breeze customer agent guide for the setup.

What it does well

  • Knowledge from your tickets, with a human in the loop. "Generate knowledge" analyzes the last 90 days of resolved tickets and drafts Q&A pairs for you to approve (HubSpot KB).
  • Batch testing (beta). Write test questions or generate them from themes in past conversations, then mark answers "Looks good" or "Looks bad", up to 8 test sets (batch testing).
  • CRM context. You can test as a specific CRM contact or segment, and previews don't use credits.

Pricing

From the customer agent page: $0.50 per resolution, paid as 50 HubSpot Credits at $0.010 each. It needs a Professional or Enterprise plan; Service Hub Professional is listed at $90 or $100 per seat with 3,000 credits a month (enough for 60 resolutions), plus a one-time $1,500 onboarding fee (Service Hub pricing). New Pro seats get 14 days of free agent usage.

Pros and cons

Pros:

  • Lowest published per-resolution price on this list.
  • Drafts knowledge from your real resolved tickets.
  • SOC 2 Type II and a HIPAA attestation on the Trust Center.

Cons:

  • "Resolved" includes any conversation where the agent cited a source or took an action and the customer didn't ask for a human within 72 hours. A manual or workflow assignment to a rep "does not, by itself, prevent the conversation from being counted as resolved."
  • Email threads reopened after 72 hours can be billed a second time.
  • Answers can drift early on:
G2

"It can be very broad, and at the beginning, it would recommend things outside of the knowledge base or try to make things up. So we had to add boundaries to it and tighten up the knowledge base."

Nolan M., G2, Small-Business

Verdict

If HubSpot is already your CRM and help desk, the Customer Agent is cheap to try and easy to scope. Read the resolution rules carefully before you forecast. If you want AI on HubSpot tickets that learns your team's voice from the start, the HubSpot Service Hub AI alternatives are worth a look.

7. Help Scout AI Answers

Best for: small teams on Help Scout who want a cheap, capped chat assistant.

Help Scout AI Answers conversation where the AI could not answer "My order was late. Why?", listing the three help articles it searched, with Improve, Reply and Note buttons, as taken from Help Scout docs

Help Scout's AI Agent is the place you configure AI Answers: knowledge, tone, guardrails and connections, reused across every Beacon (Help Scout's chat widget) (AI Agents in Help Scout). It answers from your Docs sites, public URLs, PDFs, Word and Excel files and Google Docs. It's the lightest-weight option here, which is the point. Our best AI for Help Scout roundup covers the add-on options too.

What it does well

  • The clearest resolution definition on the list. No charge if the customer escalates, searches the help center, asks more, or clicks "I still need help", and at most one charge per conversation (Help Scout pricing FAQ).
  • A hard monthly cap. When you hit it, AI Answers switches off for the rest of the cycle.
  • Guardrails that send chosen topics straight to your team.

Pricing

From Help Scout pricing: $0.75 per resolution, billed monthly, with prepaid discounts and three months of free, unlimited resolutions for new accounts. Seats are $25, $45 or $75 per user per month on annual billing, plus a free plan for up to 5 users.

Pros and cons

Pros:

  • Low per-resolution price with a hard monthly cap.
  • The clearest rules on what counts as resolved.
  • Test tab conversations aren't billed.

Cons:

  • AI Answers runs in the Beacon widget; the docs I checked don't describe it replying to email tickets.
  • Past conversations only feed "Suggested Improvements" that a person approves; they aren't a knowledge source.
  • HIPAA is only on the Pro plan, and AI features need a separate healthcare addendum (Help Scout and HIPAA).
Capterra

"The new AI features takes a lot of the anxiety out of how to respond in a respectful and professional manner."

CJ B., Capterra, Director of Customer Advocacy

Verdict

Great for a small team that mostly needs chat deflection on top of good docs. If most of your volume arrives by email, look at Help Scout AI alternatives that work inside the mailbox.

8. Ada

Best for: large teams that want a managed AI agent across chat, email and voice.

Ada simulation transcript for an order status question, showing the referenced articles, a coached instruction and the AI agent replies, as taken from Ada docs

Ada is a standalone AI agent that sits in front of your helpdesk and hands off to Zendesk, Salesforce, or any platform that accepts email-to-ticket (handoff docs). It's built for enterprises; the pricing page is a demo form that opens by asking for your yearly contact volume. Our Ada review has the long version.

What it does well

  • High-volume simulations. Up to 3,000 simulation runs a day and 1,000 stored test cases, with pass or fail against 1 to 10 expected outcomes (Simulations).
  • Voice testing that places a real call to the agent.
  • 60 supported languages, per Ada's docs.

Pricing

No public price. Ada's own blog argues for charging per conversation "regardless of outcome" over per resolution (Ada blog), but doesn't say what it charges. See Ada CX pricing for what's known.

Pros and cons

Pros:

  • Serious testing volume for regression checks.
  • Works across chat, email and voice.
  • SOC 2 Type 2 and a HIPAA report on its trust center.

Cons:

  • Simulation actions "are not mocked" and run against your live systems.
  • Five active customer-facing API tools per agent by default; more goes through your Ada team.
  • Setup can lean on hands-on work:
G2

"The setup process for flows sometimes requires more manual work and testing than expected, especially when compared to platforms that offer stronger built-in discovery features or self-optimizing flows."

Silvia H., G2, Customer Experience Manager, Mid-Market

Verdict

Ada fits an enterprise with a dedicated AI owner and a vendor relationship budget. If you want to see a price before a demo, compare the Ada alternatives first.

9. Decagon

Best for: enterprises with engineers who want to own the agent's logic in code.

Decagon builds agents from Agent Operating Procedures (AOPs), written in natural language "the same way you train human agents with SOPs", with sensitive steps like refunds validated in code (AOPs). Technical teams version them with Git. It sits over Zendesk, Salesforce and other helpdesks. Our Decagon review covers it in depth.

What it does well

  • Simulations seeded from reality. You can "upload historical transcripts from conversations where AI or human agents struggled and turn them into grounded test cases" (Decagon blog).
  • CI/CD-ready tests, auto-generated from AOPs and production conversations.
  • Suggestions that draft help-center content from how your best agents resolved the same issue.

Pricing

No public price. Decagon's own post says "the majority of our customers gravitate towards per-conversation pricing," a fixed rate for every incoming conversation (Pricing the AI Agent Economy). See Decagon pricing.

Pros and cons

Pros:

  • Code-level control for teams that want it.
  • Transcript-seeded simulations catch real failure modes.
  • SOC 2 Type II and ISO 27001:2022 (trust center).

Cons:

  • Sales-led, no self-serve trial.
  • Simulations use mock personas, not a replay graded against your team's actual reply.
  • Tuning takes time:

"The main downside is that it takes some time to set up and fine-tune everything properly. At the beginning, you need to review the responses quite closely to make sure they match your tone and business rules."

Verdict

Decagon suits an enterprise CX org with engineering support. If you don't have engineers to assign, it's the wrong shape. The Decagon alternatives list has lighter options.

10. Sierra

Best for: enterprises that want to pay for outcomes and have a vendor team build the agent.

Sierra pairs its Agent Studio (no code) and Agent SDK (code) with "an expert agent development team that has supported hundreds of deployments", and promises to "deploy in weeks" (Sierra). Its pitch is outcome-based pricing, which is the opposite end of the billing spectrum from a flat per-ticket plan. If you're torn between the two enterprise picks, read Decagon vs Sierra.

What it does well

  • Outcome pricing. "If the conversation is unresolved, in most cases, there's no charge" (Sierra blog).
  • Heavy simulation. Mock users in many languages and tones, graded by a second agent; Sierra says customers run "over 35,000 tests (and growing) each day".
  • Voice Sims that test calls from noisy places.

Pricing

No public price. Outcomes are "clear, agreed-upon criteria" set per contract, and greeter or routing flows can be billed per conversation instead. More in Sierra AI pricing.

Pros and cons

Pros:

  • Mostly no charge for unresolved conversations.
  • Vendor team does a lot of the building.
  • SOC 2 Type II, ISO 27001:2022 and ISO 42001 (trust center).

Cons:

  • "In most cases" appears twice in the pricing language; the outcome definition lives in your contract.
  • Sierra itself says complex workflows and integrations "still require code."
  • Not built for a small team that wants to start this afternoon.

Verdict

Sierra makes sense when you're a large consumer brand with budget and an appetite for a partnership. For everyone else, the Sierra alternatives are a faster path.

How to switch without breaking your queue

Switching AI tools is mostly a risk-management job. Here's the order I'd do it in, based on the switches I've watched from the support side:

  1. Export the numbers you'll judge the new tool on. Current resolution rate, reopen rate and AI CSAT, by topic. Without a baseline, every vendor will look better.
  2. Run the replacement on past tickets before customers. If the tool can't replay your history, write 30 to 50 test cases from your messiest real tickets, not the vendor's demo script.
  3. Run both side by side in draft mode. Let the new AI write internal notes while the old one keeps answering. Compare a week of drafts.
  4. Move one topic at a time. Order status first, refunds last. Keep anything that costs money behind an approval.
  5. Turn the old tool off before its renewal date, not after. Check whether committed resolutions or prepaid sessions expire.

The most common mistake I see is trusting the AI's own confidence as the handoff trigger. A builder on Reddit put it well: "The model sounds surest right before it's wrong" (r/AI_Agents). Hand off on visible signals instead, like the same order asked about twice, and read up on AI hallucinations before going fully autonomous.

Try eesel on the helpdesk you already have

If the reason you're shopping is the AI and not the helpdesk, eesel is the alternative built for exactly that. Connect your helpdesk, let it read your past tickets and macros, and run a simulation on last month's tickets before it touches a customer. You'll see how many of its replies match what your team sent, topic by topic, and where it would have escalated.

The free plan gives you 100 credits with every integration, no card. When you're ready, plans start at $299 a month for 500 tickets or chats, with unlimited seats. Try eesel free, or browse eesel pricing first.

Frequently Asked Questions

What are the best AI customer support software alternatives in 2026?
It depends on whether you keep your helpdesk. To keep it, eesel plugs into Zendesk, Freshdesk, Gorgias, HubSpot, Help Scout and more. To switch helpdesks, the built-in agents from Zendesk, Freshworks, Gorgias, HubSpot, Help Scout and Salesforce are the simplest picks, and Ada, Decagon and Sierra suit sales-led enterprise builds. The AI support agents roundup covers more.
Can I replace my helpdesk's AI without switching helpdesks?
Yes. Tools that plug into your existing helpdesk let you turn off the native bot and keep your tickets, macros and workflows. eesel works this way with Zendesk, Freshdesk and Gorgias, among others. The Zendesk AI alternatives post lists more options for Zendesk teams.
Which AI customer support software is the cheapest?
At list price, HubSpot's Customer Agent is $0.50 per resolution and Help Scout AI Answers is $0.75, but both need their own helpdesk plan. If your AI resolves a large share of tickets, a flat plan like eesel pricing ($849 a month for 2,000 tickets or chats) often works out lower. The cost per resolution guide shows the math.
What's the difference between per-resolution and per-ticket AI pricing?
Per-resolution pricing charges only when the vendor's definition of resolved is met, so the bill moves with your resolution rate. Per-ticket pricing charges for every ticket the AI works on, resolved or not, so the bill moves with volume. Zendesk's pay-per-resolution model is the best-known example of the first kind.
How do I test AI customer support software before switching?
Run it on your own past tickets before any customer sees it, then let it draft internal notes alongside your current tool for a week. Tools that only test on scenarios you write won't show you the edge cases hiding in your real queue. My guide on choosing an AI agent covers the full test plan, and the AI hallucinations post covers what to watch for.
Is AI customer support software safe for healthcare or other regulated teams?
Check the plan, not just the vendor. HIPAA coverage is often gated: Help Scout limits it to Pro, HubSpot to Enterprise for sensitive data, and eesel offers a BAA on Enterprise. Read each vendor's trust page, including the eesel security page, and confirm whether AI features need a separate addendum.
How long does it take to switch AI customer support software?
Self-serve tools that plug into your current helpdesk can draft on real tickets the same day. Moving to a new helpdesk's built-in AI is a migration project, and vendor-led platforms like Sierra advertise deploying in weeks. If you're weighing a custom build instead, read the build vs buy guide first.
