The 6 best Forethought AI alternatives in 2026

If you've been evaluating Forethought — or are an existing customer wondering what comes next — the context has changed. Zendesk acquired Forethought on March 11, 2026, and while the product continues to run for existing customers, its roadmap now answers to Zendesk's priorities rather than operating as an independent platform.

That uncertainty is enough to push many teams to look around. Even before the acquisition, Forethought had a few recurring friction points: fully sales-gated pricing with no public figures, a setup complexity that suited enterprise teams more than smaller ones, and a profile that had become closely tied to Zendesk even before the deal closed.

This guide covers six alternatives worth considering in 2026. Each section includes a screenshot of the product at launch, a full pricing table sourced from each company's own pricing page, honest notes on what works and what doesn't, and a clear read on which type of team each one fits best. The comparison table below is a good place to start if you're skimming.

Quick comparison: Forethought alternatives in 2026

---

1. Tidio

Tidio is a customer service platform built around its Lyro AI Agent, aimed primarily at e-commerce brands and SMBs. It combines live chat, ticketing, and AI in a single workspace — or you can bolt just the Lyro AI layer onto an existing help desk through Lyro Connect (available on Plus and Premium plans), which lets Lyro run on top of Zendesk, Salesforce, or other tools you already use.

Tidio's headline claim is a 67% automated resolution rate, which it backs with a money-back guarantee on the Premium plan: if Lyro doesn't hit at least 50% resolution rate for your account, you get a refund. That's unusual in this category.

The platform integrates with Shopify natively (with order lookup and product actions), plus Messenger, Instagram, WhatsApp, email, and 120+ other tools. If you're running an e-commerce store and want AI that can actually pull order data rather than just answer questions about shipping policies, Tidio's Shopify integration is one of the tightest in this list.

Pricing

Tidio offers two purchase paths: the full Customer Service Platform or the Lyro AI Agent as a standalone add-on. The prices below are billed annually.

Lyro AI Agent as a standalone starts at $32.50/mo for 50 Lyro conversations/month. You can use it with your existing help desk (Zendesk, Salesforce, etc.) without switching to Tidio's full platform.

Pros

• Free plan available with no time limit
• 7-day free trial for all paid plans
• Lyro Connect lets you add AI to an existing help desk without migration
• Native Shopify actions (check order status, process returns) on Growth+
• Resolution rate guarantee on Premium is rare in this market

Cons

• Lyro AI conversations are counted separately from platform conversations - tracking two quotas can get confusing
• The Plus plan jumps steeply from Growth ($49 to $749/month)
• Lyro Connect is only available on Plus and Premium - teams on Growth still get Tidio's own help desk, not their existing one

Who it's for: E-commerce brands that want live chat plus AI in one tool, or teams that want to add Lyro AI on top of an existing help desk without switching platforms.

2. Zendesk AI

This one has a layer of irony: Zendesk acquired Forethought, and now Zendesk's own AI is the most direct alternative for Forethought customers who were already on Zendesk. If you're running Zendesk tickets today, Zendesk AI is already in your platform - you just need to be on a Suite plan to access it.

The Forethought technology is being integrated into Zendesk's Resolution Platform. Zendesk's pricing page now shows a dedicated "Zendesk + Forethought" section advertising self-learning AI agents that work across any ticketing stack. This integration is still rolling out as of May 2026.

For teams on Zendesk's Suite plans, AI agents (Essential tier) are included from Suite Team upward. Advanced AI agents - with deeper reasoning, agent builder, and integrations - require an add-on. Zendesk also bundles Copilot (an agent-side AI assistant) into Suite + Copilot plans.

Pricing

Monthly billing is ~20% more than the annual prices above.

Pros

• No migration needed - AI is already inside the platform you're using
• Forethought technology being integrated natively (announced roadmap)
• 5-15 free automated resolutions per agent per month included in Suite plans
• 1,800+ marketplace integrations

Cons

• Per-agent pricing gets expensive at scale (10 agents on Suite Professional = $1,150/month minimum)
• Advanced AI agents requiring deeper reasoning still need an add-on purchase
• The pricing structure has many layers - AI agents, Copilot, Quality Assurance, Workforce Management are all separate line items
• Overkill if you don't need all of Zendesk's features and already have a different helpdesk

Who it's for: Teams already running Zendesk who want to keep everything in one platform and are comfortable with per-agent pricing.

3. eesel AI

eesel AI takes a different angle: instead of being a helpdesk itself, it acts as an AI layer on top of the helpdesk you're already running. Connect it to Zendesk, Freshdesk, Gorgias, or Jira Service Management, and it starts handling tickets from those systems directly - drafting responses, sending replies, routing, and escalating - without you having to move ticket history anywhere.

The platform supports 100+ knowledge sources, including Confluence, Google Docs, Notion, SharePoint, and past support tickets. The AI reads all of them and uses the combined knowledge to answer customer questions. One detail that matters in practice: eesel doesn't charge per seat. Whether you have 5 support agents or 50, the price is the same per resolved ticket.

What that means at scale: Smava handles over 100,000 tickets/month in German through eesel, and Gridwise resolved 73% of tier-1 requests in their first month. Design.com runs 50,000+ tickets/month through eesel on Freshdesk.

The platform also supports a graduated autonomy model: you can start in copilot mode where the AI drafts responses for human review, then move to full agent mode where it sends replies autonomously when confidence is high. This makes it easier to get started without risking customer experience.

Pricing

Source: eesel.ai/pricing

No per-seat fees. No platform fee unless you take the enterprise add-on. You pay for what the AI resolves.

For comparison: 1,000 regular tasks/month = $400. At 5,000 tasks/month, that's $2,000 - or $1,500 with the annual discount.

Pros

• No per-seat fees - pricing scales with ticket volume, not headcount
• No migration needed - works with your existing Zendesk, Freshdesk, Gorgias setup
• Free $50 credit to test the product with no credit card required
• Connects to 100+ knowledge sources simultaneously
• Progressive autonomy: start with drafts, move to full automation when ready
• Handles 80+ languages

Cons

• Not a full help desk - you need an existing helpdesk already running
• eesel adds cost on top of your existing helpdesk fees
• At very high volumes (10,000+ tickets/month), a flat-rate platform may be cheaper per ticket

Who it's for: Teams with an existing helpdesk (Zendesk, Freshdesk, Gorgias, etc.) who want to add AI resolution without switching platforms or paying per-seat fees. Especially strong for large teams where per-seat pricing from competitors would be expensive. Read more in our guide to AI helpdesk agents.

4. Ada

Ada sits firmly in enterprise territory. Its ACX Platform (Automated Customer Experience) is designed for companies handling hundreds of thousands of support conversations per year - its pricing page states it's a great fit for companies with at least 300,000 annual customer service conversations.

The platform covers chat, email, voice, and social messaging across any channel. Ada orchestrates multiple LLMs to balance accuracy and safety, with HIPAA, SOC2, GDPR, and AIUC-1 compliance and zero data retention policies with LLM providers - a meaningful detail for financial services and healthcare customers.

Customer results are strong: Monday.com achieved a 42% reduction in average agent handle time, Tilt reached 84% automated resolution rate on chat, and IPSY saw $2.7M in estimated annual savings with 943% ROI in four months.

The platform includes an ACX Practice offering - a professional services arm that helps companies deploy and scale Ada agents, and ACX Experts who work as an extension of customer teams to optimize performance.

Pricing

Source: Ada pricing page

Ada does not publish pricing. The pricing page is a contact form. Ada self-selects for organizations handling at least 300,000 annual support conversations, which implies a significant commitment floor. Pricing is custom based on conversation volume.

Pros

• Genuine enterprise-grade platform: HIPAA, SOC2, GDPR, AIUC-1 compliance
• Covers all channels (chat, email, voice, social messaging) from one platform
• Strong case studies with verified ROI numbers from recognizable brands
• Zero data retention with LLM providers
• ACX Practice professional services available for deployment support

Cons

• No public pricing - requires a sales conversation even for early evaluation
• Minimum fit threshold of 300,000 annual conversations means it's not for small or mid-market teams
• Long enterprise sales cycles typical

Who it's for: Large enterprises (retail, fintech, SaaS, travel) handling significant support volume who need a compliant, full-channel AI platform with professional deployment support.

5. Sierra AI

Sierra was founded by Bret Taylor (former Salesforce co-CEO and Twitter board chair) and Clay Bavor (former VP of Google Labs), and it shows in the client roster: Rocket Mortgage, Gap, SoFi, SiriusXM, Discord, DIRECTV, Brex, Wayfair, and WeightWatchers are all running Sierra agents.

The platform's Agent OS covers the full agent lifecycle: build (using its "Ghostwriter" tool that converts SOPs and transcripts into production-ready agents), optimize (automated updates based on flagged issues), and scale (multivariate experiments and observability tools). Sierra also runs an Agent Data Platform that personalizes responses based on customer history and can trigger proactive outreach based on real-world signals.

One distinctive feature: Sierra prices on outcomes rather than seats or conversations. The homepage calls this "pay for a job well done."

Pricing

Source: sierra.ai

Sierra does not publish pricing. Their model is outcome-based (you pay for resolved outcomes), but specific rates require a sales conversation. Given the client profile, this is firmly an enterprise product.

Pros

• Outcome-based pricing aligns cost with value delivered
• Ghostwriter lets non-engineers build agents from plain-language SOPs and audio recordings
• Covers voice, chat, email, and SMS from a single intelligence layer
• Strong observability tools (Explorer, Monitors, Experiments) for ongoing optimization
• Proactive engagement capabilities beyond reactive support

Cons

• No public pricing; enterprise sales cycle required
• Not accessible for small or mid-market teams given the client profile
• Relatively newer company (compared to Zendesk, Ada) so longer-term track record is still building

Who it's for: Enterprise brands that want an AI platform aligned to business outcomes rather than conversation volume, and have the engineering and operations capacity to leverage Sierra's full capabilities.

6. Decagon

Decagon positions itself as "the AI concierge for every customer" - the word choice is deliberate, signaling a goal of personalized, high-quality experiences rather than pure deflection. Its client list includes Hertz, Oura, Duolingo, Chime, Figma, Noom, Dropbox, ClassPass, and Rippling.

The platform uses Agent Operating Procedures (AOPs) - natural-language workflow definitions - as an alternative to complex configuration languages. The pitch is that product and operations teams can iterate on agent behavior without engineering support.

Decagon covers voice, chat, and email through a single intelligence layer, with cross-channel memory ensuring context carries across conversations. A recent addition, Proactive Agents, lets the platform initiate outreach rather than only responding reactively.

Results from published case studies: Duolingo achieved 80% deflection rate, ClassPass saw 95% cost reduction, and Chime reached 70% chat and voice resolution.

Pricing

Source: decagon.ai

Decagon does not publish pricing. Given the enterprise client profile and the "get a demo" call-to-action on the homepage, this is a sales-first product. Budget accordingly.

Pros

• AOPs allow natural-language agent configuration without engineering effort
• Strong voice AI capabilities alongside chat and email
• Proactive Agents feature for outbound engagement
• Cross-channel memory so context persists across voice, chat, and email
• Impressive case study metrics from recognizable consumer brands

Cons

• No public pricing
• Enterprise-focused; smaller teams are unlikely to match the minimum commitment threshold
• Newer company (less long-term track record than Zendesk or Ada)

Who it's for: High-growth consumer brands (fintech, consumer apps, e-commerce, food delivery) that want a modern, concierge-style AI experience across voice, chat, and email.

How to choose

With six strong options in front of you, the choice comes down to a few real questions:

Are you already on Zendesk? If yes, Zendesk AI is the path of least resistance - AI agents are included in Suite plans, the Forethought technology is being integrated, and there's no new vendor relationship to manage. The downside is that per-agent pricing adds up fast on large teams, and eesel AI on top of Zendesk can be cheaper once you have 10+ agents.

How big is your support volume? For under 1,000 tickets/month, Tidio's Growth plan or eesel AI's pay-per-task model both work well. Above that, compare whether per-agent (Zendesk), per-task (eesel), or per-conversation (Tidio) math works better for your situation. For 10,000+ conversations/month, Ada, Sierra, and Decagon become genuinely relevant - their enterprise-grade infrastructure and professional deployment support start to justify the sales-gated pricing.

Do you want a full platform or a layer on top of what you have? Tidio, Zendesk AI, Ada, Sierra, and Decagon are complete platforms. eesel AI is explicitly designed to work on top of the helpdesk you're already running. If you've invested in Zendesk or Freshdesk and don't want to move ticket history, eesel is worth testing first.

Does e-commerce matter to your use case? Tidio has native Shopify actions built in (order lookup, return processing) and a strong track record with DTC brands. Decagon's consumer brand roster (Hertz, ClassPass, Duolingo) also makes it a strong fit for consumer-facing businesses.

How important is pricing transparency? Tidio, Zendesk, and eesel AI all publish clear public pricing. Ada, Sierra, and Decagon require a sales conversation. If you need to get a rough budget approved internally before talking to sales, the first three are much easier to work with.

Conclusion

Forethought built a genuinely strong product before the Zendesk acquisition - the triage, resolution, and insights features were legitimate differentiators. But acquisition uncertainty is real, and "Zendesk's roadmap now decides what happens to this product" is a fair reason to look around.

If you're on Zendesk and want to stay on Zendesk, the native AI agents (and eventually the integrated Forethought technology) are the obvious path. For teams with 5-50 agents who'd rather not pay per seat, eesel AI's per-task model often works out cheaper while still connecting to whatever helpdesk you're already running. Tidio is the strongest option for e-commerce and SMBs who want a free starting point and clear public pricing. For enterprise volumes - especially financial services, consumer apps, and high-growth brands - Ada, Sierra, and Decagon each bring enterprise-grade infrastructure that Forethought matched.

None of these tools requires you to abandon your current setup. Most offer a free trial or demo-first path. The practical step is to pick one that matches your helpdesk and ticket volume, run a trial against real tickets, and measure resolution rate against your current baseline.
