The 6 best Certainly AI alternatives to consider in 2026

So, you're looking into conversational AI and have come across Certainly. One update first: certainly.io no longer resolves, and the product now sits on Cegeka's site as Certainly by Cegeka, an enterprise SaaS platform for building hybrid conversational assistants. But maybe you’re finding the customization a bit rigid, the setup is taking longer than you expected, or you're just doing your homework to see what else is out there.

Whatever your reason, you’re in the right place. The world of AI customer service tools is crowded, and it can be tough to figure out which one is actually right for your team. To save you some time, we’ve gotten our hands dirty and tested the top 6 Certainly AI alternatives for 2026. We'll get into what makes each one tick so you can find a good fit for your support team without having to start from scratch.

What are conversational AI platforms?

Before we jump into the comparisons, let's get on the same page. A conversational AI platform is essentially a toolkit that lets you build and run automated, natural-sounding conversations with your customers, whether that's on your website, through email, or in messaging apps.

This isn't your old-school, rigid chatbot that gets stuck if you don't type the exact right phrase. These modern platforms use Natural Language Processing (NLP) to actually understand the intent behind a user's question and give a helpful answer. They pull information from your knowledge base, help center articles, and even past customer chats to solve problems on their own. This frees up your human agents to handle the trickier, more nuanced issues that need a human touch.

How we picked the best Certainly AI alternatives

To make this a useful comparison, we looked at things from the perspective of a busy support team. We didn't just want a list of features; we wanted to know how these tools actually feel to use day-to-day.

Here's what we focused on:

• Getting started quickly: How fast can you go from signing up to actually having a working AI? We gave extra points to tools with a self-serve setup that didn't require getting on the phone with a sales team or looping in a developer.

• Customization and control: Does the tool make you follow its rules, or can you fine-tune how the AI behaves? We looked for platforms that let you control the AI’s personality, what it can do, and which specific questions it should handle.

• Connecting your knowledge: An AI is only as smart as the information it can access. We preferred tools that could easily connect to and learn from all the places your team knowledge lives, like your helpdesk, internal docs, and past support tickets.

• Clear pricing: Is the pricing easy to understand, or are there hidden costs? We looked for simple, predictable pricing without confusing fees for every ticket the AI resolves.

• Testing before you go live: Can you see how the AI will perform before your customers do? Platforms with good simulation modes and options for a gradual rollout scored higher because they let you launch with confidence.

A quick comparison of the top Certainly AI alternatives

The 6 best Certainly AI alternatives in 2026

Alright, let's dig into the details of each platform.

1. eesel AI

eesel AI takes a pretty unique approach. Instead of making you switch to a whole new helpdesk, it adds a smart AI layer right on top of the tools you already use, like Zendesk and Freshdesk. It feels like it was built for teams who want serious AI power without the headaches and long setup times that usually come with it.

One of the best things about it is how fast you can get up and running. You can literally sign up, connect your helpdesk and knowledge sources, and have it working in minutes, all by yourself. eesel AI immediately starts training on your old support tickets to learn your brand's voice and the most common questions customers ask. This is a huge time-saver compared to platforms that make you build everything from scratch.

You also get a ton of control. The simulation skill tests the AI's answers against hundreds of your past tickets (or generated test cases), scores each one, and suggests instruction changes, so you can see how it'll behave before you turn it on for customers. From there, you can decide exactly which types of tickets get automated and what the AI should do, from giving a simple answer to looking up order info using an API.

Pros:

• Completely self-serve: You can be live in minutes without ever talking to a salesperson.

• Connects all your knowledge: It learns from past tickets, your help center, and even internal docs in places like Confluence or Google Docs.

• Risk-free simulation: Test it on your own past tickets to see how it works before launch.

• Straightforward pricing: The monthly plans are simple and predictable, with no extra fees per ticket resolved.

Cons:

• It's a newer tool with a rapidly growing list of case studies.

• For a very small team, the sheer number of customization options might take a moment to explore fully.

Pricing:

Free plan with 100 credits and no card, then fixed monthly plans from $299/month for 500 credits (1 credit per ticket or chat). Everything is included, with no per-seat fee.

2. Tidio

Tidio is a go-to for many small and medium-sized businesses, especially in e-commerce. It bundles live chat, chatbots, and email marketing into one platform that’s pretty easy to get the hang of. Its visual chatbot builder is a standout feature, letting you map out conversation flows without needing to know any code.

Tidio's Lyro learns from website pages, FAQs, CSV or PDF files, a Zendesk Help Center import, and suggestions from past chats. Past support tickets aren't among the documented sources the way they are for eesel AI, and Tidio's real advantage is its simplicity and how easy it is to get started. The free plan is surprisingly capable, which makes it a great entry point if you're just dipping your toes into automation. Just be aware that the costs can adjust as you add more features and your conversation volume grows.

Pros:

• A great fit for small to medium businesses and online stores.

• The visual chatbot builder is very intuitive.

• There's a generous free plan to get you started.

Cons:

• Documented knowledge sources are pages, files, and past-chat suggestions rather than ticket history.

• Pricing structures may change as you scale and add more features.

Pricing:

A free plan is available. Paid plans start at $29/month.

3. LiveAgent

LiveAgent is a full-blown help desk platform. It packs live chat, ticketing, a call center, and social media tools into one system. Its AI features are one part of that bigger package, which is perfect if you’re looking to consolidate tools and have everything under one roof.

The main trade-off here is that AI isn't the platform's sole focus, it's just one of many features. So, you might not get the same level of AI customization or the advanced testing modes that you'd find in a dedicated AI tool. It's a fantastic option for teams wanting to simplify their tech stack, but probably not the right move if you love your current helpdesk and just want to add a powerful AI assistant to it.

Pros:

• A true all-in-one platform for customer service.

• Handles communication across many channels really well.

• The per-agent pricing is quite affordable.

Cons:

• AI is one feature among many, so check it against your needs.

• It works best when you utilize their entire helpdesk system.

Pricing:

Starts at $15 per agent/month billed annually ($19 billed monthly) for the Small business plan.

4. Zendesk AI

If your team is already living and breathing in Zendesk, then their built-in AI is an excellent choice. It's woven directly into the Zendesk platform, so you can build bots in the same place your agents work every day. It's outstanding at figuring out what a ticket is about, suggesting macros, and powering your help center's self-service options. It can also draw on external content such as Confluence, SharePoint, and websites through knowledge connectors, up to 50 sources.

The biggest plus is the seamless integration. It’s designed to work specifically with Zendesk data, providing a reliable and unified experience for users of the platform. This ensures that the AI is perfectly tuned to your existing support environment. AI agents are included in every Suite and Support plan, with a monthly allowance of automated resolutions per agent and a per-resolution charge beyond it.

Pros:

• Works seamlessly for teams already using Zendesk.

• Makes excellent use of your existing Zendesk data and macros.

• Keeps the experience consistent for both agents and admins.

Cons:

• It is optimized specifically for the Zendesk ecosystem.

• Knowledge from other tools has to be connected as external sources, up to 50.

• Automated resolutions beyond the included allowance are billed ($1.50 committed, $2.00 pay-as-you-go).

Pricing:

AI agents are included in Zendesk Suite and Support plans, from $55 per agent/month (Suite Team, billed annually). Automated resolutions beyond the allowance cost $1.50 on a committed plan or $2.00 pay-as-you-go.

5. Boost.ai

Boost.ai is a powerful platform designed for large companies, especially those in industries with a lot of rules, like banking and insurance. It has sophisticated language understanding, robust security, and is built to handle a massive number of conversations.

This is the kind of tool that offers significant enterprise-grade capabilities. The process reflects this depth, involving a sales-led journey with a dedicated setup period. It's a great choice for corporations with complex requirements that need a highly specialized implementation.

Pros:

• Built to handle enterprise-level scale and security needs.

• Very advanced conversational AI and language processing.

• Well-regarded in regulated industries.

Cons:

• The implementation process is thorough and led by a sales team.

• It is a sophisticated tool that requires a dedicated investment of time and resources.

• Best suited for teams that have established, complex requirements from day one.

Pricing:

Custom enterprise pricing is available upon request.

6. YourGPT.ai

YourGPT.ai is another platform focused on making it easy for anyone to build a custom AI chatbot without code. You train it by feeding it data from your website, documents, or an FAQ page. It connects with a bunch of messaging apps like WhatsApp, Slack, and Messenger.

Its main draw is its simplicity, which makes it a good option for simple tasks like capturing leads or answering basic questions. However, it may not have the deep integrations with helpdesks or the automation features needed for a full-fledged customer support setup. It also works differently than tools that learn from past tickets, making it a better fit for simpler use cases.

Pros:

• A simple, no-code way to build a chatbot.

• Works with a wide variety of messaging apps.

• The starting price is very affordable.

Cons:

• Doesn't integrate as deeply with customer service helpdesks as some other tools.

• Is not typically trained on historical support ticket data.

• Best for teams with straightforward automation workflows.

Pricing:

Starts at $39/month billed annually ($59 billed monthly) for the Essential plan.

A few tips for choosing between Certainly AI alternatives

Picking the right tool from a list of Certainly AI alternatives can feel like a big decision. Here's a little advice to help you think it through:

• Look at what you're already using: Do you want a whole new helpdesk or do you want to make your current one smarter? If you're happy with your current setup, look for a tool like eesel AI that works within your ecosystem instead of forcing you to move everything.

• Value speed and flexibility: In this day and age, you shouldn't have to wait months to get a new tool up and running. Lean towards self-serve platforms that let you experiment and launch on your own timeline.

• Ask for proof, not just promises: A sales demo can look amazing, but seeing a simulation on your own past data tells the real story. Always ask how you can verify a tool's performance before you sign a contract.

• Think about where your knowledge lives: Is all your team's expertise in one help center, or is it scattered across different documents and platforms? Make sure the tool you pick can connect to all of it.

Finding the right fit among Certainly AI alternatives

While Certainly is a decent tool, the best AI platform is really the one that fits how your team already works. For small businesses that need a simple, all-in-one tool, Tidio or LiveAgent are great places to start. For massive companies with strict security needs, Boost.ai is built for the job.

But for teams looking for that sweet spot between power, control, and ease of use, eesel AI really stands out. It gives you the ability to automate even your most complex support issues without having to ditch the tools you and your team already know and love. By learning from your team's collective knowledge and letting you test everything safely first, it offers a smarter and faster way to deliver amazing customer service.
