I tested 7 top platforms to find the best AI for customer service in 2025

You’ve seen the hype around using AI for customer service. But if you're like me, you've also heard the horror stories: chatbots inventing fake policies, setup processes that take months and a team of developers, and the nagging fear of an AI going rogue on your customers (looking at you, Air Canada). It’s enough to make anyone want to stick with the tried-and-true manual way of doing things.

But I had to know if you could get the benefits of AI without all the headaches. I decided to cut through the marketing fluff and find out for myself. I got my hands on the top platforms and judged them on what actually matters to a busy support team: Can I set it up myself without a PhD in engineering? Will it give accurate answers? And can I actually control what it does?

This is the no-nonsense guide I wish I’d had.

What exactly is AI for customer service?

First, let's clear something up. When we talk about AI for customer service today, we're not talking about those clunky, rule-based chatbots from a few years ago that couldn't understand anything outside of a script. Think of it more like a smart layer that works with your support team to figure out what customers need and helps them get it, fast.

It’s really a toolkit of a few different things working together:

• AI Agents: These are the autonomous workers in your help desk. They can read a new ticket, understand the problem, give a full answer, and close it out without a human ever having to touch it.

• AI Copilots: Think of these as a helpful sidekick for your human agents. They can draft replies in your brand's voice, find the right help articles, and summarize long, complicated ticket histories in seconds.

• AI Triage: This is the super-organized gatekeeper for your inbox. It automatically reads, tags, and routes incoming tickets to the right team, clearing out the noise so agents can focus on tickets that need a human touch.

• AI Chatbots: These are the friendly faces on your website or app. They give instant answers 24/7 and know when to hand a conversation over to a person.

The point isn't to replace your support team. It's to free them from the 80% of repetitive questions that burn them out, so they can spend their brainpower on the complex, interesting problems that actually build customer loyalty.

How we chose the best AI for customer service tools

I wasn't impressed by flashy demos or buzzwords. I wanted to see how these tools held up in the real world. My criteria were simple and based on what any support leader would actually care about.

Here’s what I was looking for:

• Can I set it up myself, fast? I gave major points to platforms that were genuinely self-serve. I wanted to see if I could get from signup to a working AI in minutes, not months, without being forced into a sales call.

• Does it make stuff up? Accuracy is everything. I looked for tools that let me ground the AI in my team's own verified knowledge. Crucially, I wanted a "simulation mode" to test its answers on my real data before it ever spoke to a live customer.

• Can I control it, or does it control me? The best tools let you set the rules. I wanted to be able to tell the AI exactly which tickets to handle, what actions it's allowed to take (like looking up an order status), and what its personality should be.

• Does it work with my current tools? A great AI tool shouldn't force you to change your entire workflow. It should plug right into your existing help desk and knowledge bases, whether that's Google Docs or Confluence.

• Will I understand the bill? No one likes surprise fees. I looked for simple, predictable pricing. Flat-fee subscriptions got a thumbs-up, while confusing "per-resolution" models that charge you more as the AI gets better got a hard pass.

The 7 best AI for customer service platforms in 2025

After spending time with each of these tools, here’s my breakdown of the best options out there.

1. eesel AI

Description: eesel AI is built for teams who want serious AI power without the implementation pain. It connects directly to your help desk (like Zendesk, Freshdesk, or Intercom) and pulls knowledge from everywhere your team already works: past tickets, your help center, Confluence, Google Docs, and more. Its best feature is a simulation mode that tests the AI on thousands of your past tickets, showing you exactly how it will perform before you turn it on.

• Pros:

  • Genuinely self-serve: You can sign up and launch an AI agent in less than 10 minutes without talking to a salesperson. It’s for real.

  • Test with confidence: The simulation mode is a huge deal. It takes all the risk and guesswork out of launching an AI.

  • Total control: A simple editor lets you define exactly which tickets to automate and what the AI can do, from tagging tickets to making API calls to check an order status.

  • Transparent pricing: Simple, flat-fee monthly plans. You know exactly what you're paying, with no scary "per-resolution" fees that punish you for success.

• Cons:

  • As a newer player, it doesn't have the massive brand name of the enterprise giants.

  • While you can set up powerful custom actions on your own, having some basic familiarity with APIs is helpful for the most advanced stuff.

• Pricing: eesel AI's pricing is straightforward, starting at $299/month for the Team plan. The Business plan, which includes training on past tickets and AI actions, is $799/month.

• Best for: Any team that wants a powerful, reliable AI solution they can set up themselves today without needing a huge budget or having to replace their existing tools.

2. Intercom (Fin)

Description: Fin is Intercom's native AI agent, and it’s designed to work perfectly within their platform. It's powered by the latest language models, and its ability to hold a conversation is very impressive. If your company is already all-in on Intercom, Fin can handle complex questions and feels like a natural part of the product.

• Pros:

  • Excellent conversational AI that understands nuance and context very well.

  • Seamless integration if you're already an Intercom customer.

  • Works for both customer-facing chat and helping agents behind the scenes.

• Cons:

  • The pricing is per-resolution, which can get incredibly expensive and makes your bill a total surprise each month. Your support costs go up as your AI gets better, which just feels backward.

  • It's designed for the Intercom world. If your knowledge is stored elsewhere, it's not nearly as effective.

  • It doesn't have a real simulation mode, so you're flying blind when you first turn it on.

• Pricing: Intercom's pricing for Fin is $0.99 per resolution. This is on top of what you already pay for the main Intercom platform.

• Best for: Companies deeply committed to the Intercom platform who are willing to pay a premium for top-tier conversational AI and can live with a variable, usage-based bill.

3. Zendesk AI

Description: Zendesk AI is the built-in intelligence for the world's most popular help desk. Its main advantage is that it's native. You get AI agents and agent-assist tools without ever leaving the Zendesk interface. It’s been trained on a ton of customer service data, so it has a good starting point for common questions.

• Pros:

  • Effortless integration for the millions of teams already using Zendesk.

  • The agent-assist tools (Copilot) can really make agents more efficient.

  • It has a solid foundation for handling general support inquiries.

• Cons:

  • It's a walled garden. The AI mostly learns from your Zendesk data and has a hard time using knowledge from outside sources like internal wikis.

  • Customization is pretty limited. You're mostly stuck with the workflows Zendesk gives you, with less fine-tuned control than other tools offer.

  • It can be a surprisingly expensive add-on, with different fees for different AI features.

• Pricing: Zendesk's pricing is layered. Basic AI is in their Suite plans (starting at $55/agent/month). The more powerful Advanced AI add-on is another $50/agent/month, and the Copilot add-on for agent assistance is yet another $29/agent/month.

• Best for: Teams who live and breathe Zendesk and prefer a native, all-in-one solution over a more powerful third-party tool.

4. Salesforce Einstein

Description: Salesforce Einstein is the AI from the heavyweight champion of CRM. It's an enterprise-level platform that sprinkles AI across the entire Salesforce universe, including Service Cloud. Its main strength is pulling from the massive amount of customer data already in Salesforce to personalize every interaction.

• Pros:

  • Incredible integration with Salesforce data, which allows for very personalized AI responses.

  • Extremely powerful and built to scale for huge, complex companies.

  • It's backed by one of the biggest names in business software.

• Cons:

  • The complexity is staggering. This isn't a tool you just "turn on." It's a full-blown implementation project that usually requires expensive consultants and several months.

  • It's complete overkill for most small and medium-sized businesses.

  • Pricing is famously hard to find. You can't just check a pricing page; you have to go through a long sales process.

• Pricing: Salesforce doesn't list a price for Einstein AI. It's bundled into various Service Cloud editions, which range from $25 to $300 per user/month, but getting the full AI features requires a custom enterprise deal.

• Best for: Large companies that already run their business on Salesforce and have the budget and team for a major implementation project.

5. Forethought

Description: Forethought is a standalone AI platform that aims to provide an AI that can handle customer issues from start to finish. It offers a set of tools for solving tickets, classifying them, and assisting agents. It connects with the major help desks and sells itself as a premium option.

• Pros:

  • A strong focus on resolving issues completely, not just answering simple questions.

  • It integrates with multiple help desks, so you're not locked into one system.

  • Their AI models are generally considered to be high-performing.

• Cons:

  • There's no self-serve option. You have to schedule a demo and go through a sales process just to get started.

  • Pricing isn't public. The "Get a Quote" button means you have no idea what it will cost, making it tough to compare options.

  • Getting it set up can be more involved than with simpler, self-serve tools.

• Pricing: Forethought's pricing is entirely custom. You have to ask their sales team for a quote. This lack of transparency is a big drawback for teams that need to move fast.

• Best for: Teams with big budgets who want a high-touch, managed AI solution and don't mind a traditional enterprise sales cycle.

6. Freshdesk (Freddy AI)

Description: Freddy AI is the native AI solution for the Freshdesk help desk. Much like Zendesk's AI, its biggest strength is how tightly it's integrated. It offers AI agents for instant answers and a copilot to help human agents. It's a solid choice for teams already using the Freshworks platform.

• Pros:

  • Smooth setup and experience for existing Freshdesk customers.

  • Offers a good blend of full automation and agent-assist features.

  • The bundles can offer decent value for the price.

• Cons:

  • It's another case of ecosystem lock-in; it works best with data already inside Freshdesk.

  • The pricing can get confusing, with a mix of per-agent fees, add-on costs, and usage-based charges for the AI agent.

  • It doesn't have an advanced simulation mode to test performance before going live.

• Pricing: Freshdesk's pricing has a few parts. The main plans start around $15-$49/agent/month. The Freddy AI Copilot is an add-on for $29/agent/month, and the autonomous Freddy AI Agent is usage-based, costing $100 for every 1,000 sessions.

• Best for: Small to mid-sized businesses that are already happy Freshdesk customers and want an easy-to-enable native AI.

7. IBM watsonx

Description: Let's be clear: IBM watsonx isn't a customer service tool you can just buy and use. It's a massive AI and data platform for enterprises to build their own AI solutions. It's a toolkit for developers and data scientists, not a plug-and-play solution for a support leader.

• Pros:

  • Incredibly powerful and flexible if you want to build a completely custom AI solution from scratch.

  • Backed by IBM's long history in AI research and enterprise software.

  • Offers strong governance features for companies in highly regulated industries.

• Cons:

  • This is not an AI for customer service product. It's a developer platform.

  • You'll need a big investment in developers and data scientists to build anything useful.

  • The complexity is off the charts for anyone just looking to automate common support tickets.

• Pricing: As you'd expect, IBM watsonx has complex, consumption-based pricing that is custom for every client. There's no simple plan to choose from.

• Best for: Fortune 500 companies with dedicated AI engineering teams who need to build custom AI applications, not for a support team looking for a ready-made tool.

4 tips for choosing the right AI for customer service (and avoiding the pitfalls)

Jumping into AI for customer service can feel risky, but it doesn't have to be. Follow these four simple rules to make sure you get it right.

1. Test it before you trust it. This is non-negotiable. Before you let an AI talk to your customers, you have to know how it will perform. The best platforms let you run simulations on thousands of your real, historical tickets. This is the only way to de-risk the project and get an honest forecast of your automation rate. Don't settle for a canned demo.

2. Start small to win big. Don’t try to automate everything on day one. That's a recipe for disaster. The smart way to roll out AI is to pick a few simple, high-volume ticket types to automate first (like "Where is my order?"). A great tool will let you do this easily and send everything else to a human. Once you see it works, you can slowly give the AI more responsibility.

3. Feed it your own knowledge, not the whole internet. AI "hallucinations" happen when the model doesn't have the right context. The most reliable AI tools are the ones that connect to all of your company’s knowledge, your help center, your internal wikis like Confluence, and even the wisdom hidden in your past support tickets. This ensures its answers are based on your reality, not a random guess from the web.

4. Beware of 'pay-per-answer' pricing. Paying for each ticket the AI solves sounds fair at first, but it can bite you. This model means your bill goes up every month as your AI gets more successful. It makes budgeting impossible and punishes you for automating more. A transparent, flat-fee subscription is almost always a better, more predictable choice.

The right AI for customer service makes customer service human again

Look, picking the right AI for customer service platform isn’t about chasing the flashiest tech. It's about finding a tool that’s easy to set up, consistently reliable, and gives you complete control. The real goal is to automate the repetitive noise so your talented support team can spend their time on what people do best: building relationships, solving tough problems, and creating experiences that customers remember.

A platform like eesel AI was built for exactly this. It lets you start small, test everything safely in a simulation, and connect all your scattered knowledge without writing a single line of code. You can be up and running in minutes, not months, and immediately see how much time you can give back to your team.
