The 7 best Zendesk AI apps in 2025

If you’ve ever scrolled through the Zendesk marketplace, you know there are over 298 AI apps to choose from. It’s a lot. And while Zendesk is a great platform, its native AI can feel a bit basic. It often has a tough time keeping up with real customer conversations or giving you the deep control your team actually needs. This leaves a lot of support leaders hunting for Zendesk AI apps that can seriously help with workflows and reduce the agent pile-on.

But who has time to sit through dozens of demos and sales calls to find the right one? I’ve done that work for you. This guide gets straight to the point, highlighting the 7 best Zendesk AI apps that actually do what they say they will.

What are Zendesk AI apps?

Simply put, Zendesk AI apps are tools you can add to your Zendesk account to give it new powers. Zendesk has its own AI for things like summarizing tickets and running simple bots, but these third-party apps plug right in to handle more advanced or specialized tasks.

Think of them as upgrades for your support team. Some are full-on AI agents that can resolve tickets by themselves, while others act as a helpful copilot, helping your human agents write replies more quickly. The really good Zendesk AI apps don’t just live in your help desk; they connect to all your team’s knowledge, whether it’s in Confluence, Google Docs, or past tickets, giving you accurate answers without making you jump between tabs.

How we picked the top Zendesk AI apps

To make this list actually useful, I focused on what busy support teams care about. I didn’t just tick off features from a marketing page; I looked at how these apps would perform in the real world.

Here’s what I was looking for:

• Can you get started quickly? I leaned towards tools with a self-serve setup. No one wants to be forced into a long sales cycle or mandatory demo just to see if a tool is a good fit.

• How much control do you get? The best apps let you decide exactly which tickets the AI should touch, what its personality sounds like, and how it connects to your other tools.

• Where does it get its knowledge? An AI is only as smart as the information it can access. I prioritized apps that could learn from lots of different places, especially old tickets and internal documents.

• Can you test it safely? Being able to see how the AI would perform on your past tickets before you unleash it on customers is a huge plus. Apps that offer a simulation mode got extra points.

• Is the pricing straightforward? No hidden fees or confusing costs. I looked for clear pricing models that don’t charge you more as the AI successfully resolves more tickets.

The 7 best Zendesk AI apps in 2025

1. eesel AI

Best for: Teams that want a powerful, all-in-one AI platform that’s incredibly simple to set up and manage.

eesel AI gets a top spot because it tackles the most common frustrations with AI tools: complicated setups, zero control, and pricing that punishes you for growing. It’s a complete package with an AI Agent, AI Copilot, and AI Triage all in one place, so you can automate your frontline support without leaving your help desk.

The whole philosophy behind eesel AI is "go live in minutes, not months." You can connect your Zendesk account in one click, point the AI to your knowledge sources (like Confluence or past tickets), and get everything running on your own. There are no mandatory demos just to try it out.

Its most impressive feature is the simulation mode. Before the AI ever talks to a real customer, you can run it on thousands of your old tickets to see exactly how it would have replied. This gives you a solid forecast of your automation rate and lets you tweak the AI’s behavior until you’re comfortable. You can start small by automating just one type of simple ticket and expand from there.

The eesel AI Copilot assists agents directly within Zendesk, providing instant answers and drafting replies to improve efficiency.

Pros:

• Genuinely self-serve: You can set it up and launch without ever talking to a salesperson.

• Powerful simulation: Test on your own historical tickets to see how it works before you flip the switch.

• Connects to everything: Pulls knowledge from help centers, past tickets, Confluence, Google Docs, and more.

• You’re in the driver’s seat: You decide which tickets to automate and what the AI is allowed to do.

• Clear pricing: A flat monthly fee, so no surprise bills for resolving too many tickets.

Cons:

• It’s a complete platform, so it might be more than you need if you’re just looking for one tiny feature (like a ticket translator).

Pricing:

eesel AI’s pricing is based on a flat monthly fee for AI interactions, not how many tickets it solves. All the main products are included in every plan.

• Team: $299/month for up to 1,000 AI interactions, 3 bots, and integrations with your help center and Slack.

• Business: $799/month for up to 3,000 AI interactions, unlimited bots, and adds the ability to train on past tickets, use AI for triage, and run bulk simulations.

• Custom: Available for teams with advanced needs, like handling really complex workflows or needing unlimited interactions.

2. Kaizo

Best for: Teams focused on agent performance and AI-driven Quality Assurance (QA).

Kaizo uses AI differently. It’s less about deflecting tickets and more about helping you manage and coach your human support agents. It plugs into Zendesk and looks at 100% of your conversations to score them, find coaching moments, and keep track of agent performance.

Its coolest feature is the gamified dashboard. Agents earn points and level up on leaderboards, which can be a fun way to keep everyone motivated. For managers, Kaizo offers a deep dive into team productivity and quality, saving you hours of sifting through tickets manually.

It’s fantastic for QA and performance management, but it’s not a tool for automating customer replies. It’s built to make your human team stronger, not to handle the frontline work for them.

Pros:

• Takes the manual work out of QA, which is a huge time-saver for managers.

• The gamification can make work more engaging for agents.

• Gives you clear, useful data on your team’s performance.

Cons:

• Doesn’t actually automate ticket responses for customers.

• If you’re not careful, the heavy focus on metrics could feel like micromanagement.

Pricing:

Kaizo’s pricing is per user, per month.

• Growth: $16 per user/month for up to 25 seats. This plan includes most of the core features like QA scorecards and performance reports.

• Professional & Enterprise: You have to contact their sales team for pricing on these plans, which add unlimited seats and more advanced AI features.

3. Ada

Best for: Large, enterprise companies that need a heavy-duty, no-code chatbot builder.

You’ve probably heard of Ada; they’re a big player in the chatbot world for a reason. They offer a robust platform for building and launching chatbots that can handle a ton of customer questions. Its biggest selling point is the user-friendly, no-code chatbot builder that lets your non-tech folks design some pretty complex conversation flows.

Ada is meant to be the first stop for customers. It handles the common stuff and then passes more complex issues to a human agent in Zendesk with all the context. It also integrates with a lot of other business systems.

The main catch is that it’s aimed squarely at the enterprise market. You can’t just sign up for a trial; you have to schedule a sales demo. The pricing is custom and usually involves a hefty annual contract, which puts it out of reach for most smaller teams.

Pros:

• A powerful and easy-to-use no-code chatbot builder.

• Built to handle a very high volume of chats.

• Does a good job of handing off conversations to human agents.

Cons:

• You have to talk to a salesperson to even see the product.

• The price tag is high, with custom quotes and annual contracts.

• It’s less focused on learning from messy, unstructured knowledge like your past tickets.

Pricing:

Ada’s pricing is not public. You have to fill out a form, give them your company info, and then book a call with sales to get a quote. This is pretty standard for enterprise software but not great if you just want to see a price.

4. Stylo Assist

Best for: Teams who want a simple ChatGPT-powered helper for drafting replies.

Stylo Assist is a no-frills app that puts ChatGPT right inside the Zendesk agent view. Its main job is to help agents write replies faster. It reads the customer’s message and suggests a response based on your help center articles.

It’s a light tool that does one thing pretty well: speed up manual typing. If your team is constantly writing out similar answers, Stylo can give them a good head start. But it’s not an automation platform. It won’t resolve tickets on its own or learn from past agent conversations. It’s strictly an assistant for your human agents.

Pros:

• Super simple to install and get started with.

• Generates replies with a single click.

• Can cut down the time agents spend typing.

Cons:

• It only learns from your public help center, not from past tickets or internal wikis.

• Doesn’t offer any real automation or triage features.

• Lacks advanced options like simulation or custom actions.

Pricing:

According to its Zendesk Marketplace page, Stylo Assist starts at $19 per agent/month and has a 7-day free trial.

5. Thank You AI GPT

Best for: Teams that want to automatically close those annoying "thank you" messages.

This app is niche, but honestly, it’s pretty great. Every support team knows the pain of a ticket getting reopened just because a customer replied "thanks!" It messes with your metrics and adds pointless work for agents who have to close it again.

Thank You AI GPT fixes that one specific problem. It uses AI to figure out when a customer’s reply is just a thank you note and closes the ticket automatically. It’s surprisingly accurate and saves your team from a small but constant headache. It does its job perfectly, but that’s all it does.

Pros:

• Solves a common and frustrating problem really well.

• Easy to set up, and it just works in the background.

• Makes your support metrics more accurate.

Cons:

• It only has one, very specific function.

• The per-ticket pricing could add up if you have a high volume of tickets.

Pricing:

Thank You AI GPT uses a usage-based model, which you can find on its Zendesk Marketplace page.

• Free: Up to 50 "thank you" tickets solved per month.

• Growth: $29/month for up to 200 tickets.

• Pro: $99/month for up to 1,000 tickets.

• Enterprise: $299/month for up to 3,500 tickets.

6. Macha

Best for: E-commerce companies that need AI tied to their store data and internal processes.

Macha is a collection of AI apps for Zendesk that are built with e-commerce in mind. Its main tools are an AI Email Writer, Translator, and Analyzer. The cool part about Macha is its ability to connect to other tools like Notion and Shopify to pull information directly into a ticket.

For example, it can match a ticket to the right SOP you’ve stored in Notion and walk the agent through the next steps. This is perfect for teams that have really detailed, documented workflows. The downside is that getting started usually requires a demo, and its knowledge comes from structured documents, not from the subtleties of thousands of past customer conversations.

Pros:

• Great integrations with Shopify and Notion.

• Helpful for guiding agents through specific, documented procedures.

• Offers a suite of different tools for different jobs.

Cons:

• Not as focused on a quick, self-serve setup.

• Relies more on formal documentation than learning from historical ticket data.

• You have to dig a bit to find pricing information.

Pricing:

Macha’s pricing isn’t on their main website. According to their Zendesk Marketplace page, the "Macha AI Suite" starts at $29 per agent/month, with different tiers depending on which apps you need.

7. Knots.io

Best for: Teams that want to buy small, separate apps for very specific automation tasks.

Knots.io is like an app store within Zendesk. They offer a library of over 25 individual apps, and each one is built to solve a single problem. For instance, they have one app to "Remove Attachments," another to "Detect Language," and another to "Merge Tickets."

This pick-and-choose approach is great if you have one or two little annoyances you want to fix without buying a whole platform. The catch is that if you want to build a complete automation flow, you might end up buying, setting up, and managing several different apps, which can get complicated and expensive. It’s the total opposite of an an all-in-one platform.

Pros:

• The a la carte model lets you pay for only what you need.

• The apps are built to work natively inside Zendesk.

• Good for teams that don’t need or want a full AI platform.

Cons:

• Juggling and paying for a bunch of individual apps can become a headache.

• There’s no single dashboard to see how all your AI automations are performing together.

Pricing:

Knots.io offers bundled pricing, so you can’t buy just one app.

• Free: Includes their "Merge Tickets" app only.

• Essentials: $269/month for a bundle of 3 apps and up to 5,000 processed tickets.

• Power Suite: $899/month for 10 apps and up to 30,000 tickets.

• Enterprise: Starts at $1,900/month for all their apps and more volume.

Tips for choosing the right Zendesk AI apps

Picking the right tool doesn’t have to be overwhelming. Here are a few practical tips to help you decide:

1. Figure out what’s actually broken. Are you buried in repetitive tickets? Is your QA process a nightmare? Are agents just typing too much? Pinpoint your biggest headache first and look for a tool that fixes that. Don’t get distracted by a long list of shiny features you’ll never touch.

2. Look for tools you can try yourself. Your time is precious. Seek out tools like eesel AI that let you sign up and test them with your own data without a sales pitch. A simulation mode is a sign of a confident product; it’s a risk-free way to see what the tool can do before you commit.

3. Think about where your knowledge lives. The best AI learns from the same places your team does. If all your team’s wisdom is scattered across past Zendesk tickets, Google Docs, or Confluence, make sure the app you pick can connect to those sources easily.

4. Keep an eye on per-resolution pricing. It might sound good initially, but paying for every ticket the AI solves can lead to surprise bills that grow over time. A flat monthly fee is predictable and lets you scale your automation without worrying about the cost.

Find an AI partner, not just a tool

The right Zendesk AI app can do more than just close tickets. It can give your team breathing room to focus on the complex, human conversations that really matter. While some apps solve one small problem, a platform that’s easy to set up, gives you complete control, and lets you test it out safely will give you the best results in the long run.

If you’re ready to see what a self-serve, controllable AI platform can do for your Zendesk workflow, try eesel AI for free. You can connect your knowledge sources and see how it would have performed on your past tickets in just a few minutes.
