I tried 7 platforms to find the best free AI chat in 2025

We all want to give our customers instant, 24/7 support, but let's face it, most of us don't have an enterprise-level budget. Free AI chat tools are supposed to be the answer, but finding one that isn't just a frustrating, feature-locked demo can be a real headache.

So, I did the dirty work. I signed up for the most popular platforms, clicked around, and read the fine print to find the best free AI chat options that actually deliver.

What is a free AI chat tool and why does it matter?

Think of AI chat as more than just that little pop-up window on a website. We're not talking about those old, clunky chatbots that gave you an error if you didn't type the exact right keyword.

Modern AI chat uses some pretty smart tech (Natural Language Processing or NLP, if you're curious) to understand what people are actually asking and talk back like a real person. It can answer tricky questions, remember past chats, and even connect to your other tools to do things like check an order status. The whole point is to get that level of help without the giant price tag, letting you focus on bigger things than answering "Where's my package?" for the tenth time today.

How I picked the best free AI chat tools

Let's be real: "free" can mean a lot of different things. Some "free" plans are so limited they're basically just an ad for the paid version. I wanted to find tools that were actually useful right out of the box.

Here's what I looked for:

• A genuinely useful free tier. Does the free plan actually let you do anything? I looked for tools that weren't just glorified trials and checked the limits on agents and chats.

• Real AI features. Is there some actual "AI" in the AI chat? I looked for some kind of smart automation or bot features you could use without paying.

• Simple setup. How fast can you get it working without calling in a developer? The quicker, the better.

• Good integrations. A chat tool shouldn't live on an island. I checked if it could play nice with other software you're probably already using.

• Room to grow. What happens when your business grows? I looked at the upgrade path to make sure it wouldn't cost a fortune later on.

The 6 best free AI chat platforms

1. eesel AI

Okay, so eesel AI isn't a "free forever" tool, but it's at the top of my list for a reason. Its free trial gives you the keys to the entire kingdom, which is rare. You can sign up and build a chatbot trained on your own help docs or even your Shopify store in about five minutes flat, no sales call needed. It's the best way to see what a real AI chat can do without dropping any cash.

Key Features on Trial:

• Get it live in minutes. The setup is incredibly straightforward. You connect your knowledge sources, tweak the AI's personality, and pop the chatbot on your site without having to talk to a salesperson.

• Connects to your existing tools. It pulls information from places you already use, like Google Docs and Confluence, and can pass conversations to help desks like Zendesk or Intercom.

• You're in control. You can set rules for what the bot can and can't answer, making sure it always stays on-brand and hands off tricky questions to a human.

• Great for e-commerce. For online stores, it can learn your product catalog to give recommendations, find orders, and handle returns like a 24/7 sales assistant.

Limitations:

• The free access is a trial, not a permanent plan. You'll have to upgrade to keep using it.

Pricing:

eesel AI has a full-featured free trial to start. Paid plans start at $239/month (billed annually) and are based on features and usage, so you don't get hit with surprise fees.

2. Tawk.to

If you're looking for truly, 100% free live chat, Tawk.to is probably what you've been searching for. Their whole deal is giving away their main software (live chat, tickets, knowledge base) for free. Seriously. Unlimited agents, unlimited chats.

Their main thing is live chat with real people, but they've started adding an "AI Assist" feature as a paid add-on, so there's a path to automation if you need it.

Key Features:

• Actually free. The main platform costs nothing, with no limits on agents or chats.

• More than just chat. It comes with a ticketing system, a knowledge base, and some basic CRM tools.

• Easy to customize. You can change the look of the chat widget to match your brand. You can even pay a small fee to remove their branding.

• Optional AI. The AI Assist add-on can help your team with things like summarizing chats or rephrasing messages.

Limitations:

• The AI features aren't part of the free plan; you have to pay for the add-on.

• The interface can feel a bit busy since there are so many features included.

Pricing:

The core software is free. You can pay for extras like removing the branding ($19/mo) or for the AI Assist feature.

3. Freshchat

Freshchat, from the folks at Freshworks, is a great option if you have a small team. Their free plan is pretty generous, giving you up to 10 spots for agents. It pulls your chat, email, and social messages into one inbox, which is super handy.

Key Features:

• Good free plan. With support for up to 10 agents, it works well for small but growing teams.

• One inbox for everything. Manage chats from your website, email, and Facebook Messenger all in one spot.

• Basic bots included. The free plan lets you set up some simple bots to handle common questions.

• Connects to other Freshworks tools. It works smoothly with other products like Freshdesk if you need a bigger support setup.

Limitations:

• The really powerful "Freddy AI" features are only on the paid plans.

• The free plan limits how many contacts you can message in marketing campaigns.

Pricing:

Freshchat has a "Free" plan. Paid plans start at $19 per agent, per month, which unlocks more features and smarter AI.

4. Crisp

Crisp feels clean and modern right away. The free plan is definitely geared toward solo operators or maybe a two-person team. You get a couple of seats and a shared inbox for your website chat and emails. It’s a solid, no-frills starting point.

Key Features:

• Clean and simple. The interface is really easy to get the hang of.

• Shared inbox. It brings your website chats, contact form submissions, and emails into one place.

• E-commerce ready. The free plan connects with platforms like Shopify and WooCommerce.

• Good for pairs. Even the free plan gives you two seats so you can work with a teammate.

Limitations:

• The catch is you're limited to 100 customer profiles on the free plan.

• You have to upgrade for a knowledge base, automated chat triggers, and most other integrations.

• The more advanced AI features are locked in the pricier plans.

Pricing:

A "Free" plan is available. Paid plans start at $45 per month for the whole workspace.

5. Chatwoot

For the more technical folks or anyone who loves open-source, there's Chatwoot. They have a free "Hacker" plan that gives you the basics for a small team. Because it's open-source, you have the option to host it yourself for total control.

Key Features:

• Open source. You can see the code and even host it on your own servers if you want.

• Developer friendly. It has good APIs and connects with tools like Dialogflow for building your own custom bots.

• A decent free plan. The Hacker plan is a solid starting point with live chat and basic team tools.

• Slack integration. You can reply to customer chats right from Slack, even on the free plan.

Limitations:

• The free plan only keeps your data for 30 days and caps you at 500 conversations a month.

• You'll need a paid plan for a help center, automation rules, and other channels like email or WhatsApp.

Pricing:

The "Hacker" plan is free. Paid cloud plans start at $19 per agent, per month.

6. Olark

Olark is all about simplicity. After their 14-day trial, you can switch to a free plan, but it's... very limited. You get one agent and only 20 chats a month. This is really only an option if you're a one-person show with a super low-traffic site and just want a way for people to reach you live every now and then.

Key Features:

• Easy to use. Olark is known for being simple to set up and manage.

• Customizable chatbox. You can easily change the colors and style of the chat widget.

• Simple rules. The free plan includes some basic rules for when the chat box should appear.

Limitations:

• The free plan is tiny: just one agent and 20 chats per month.

• All the powerful stuff, like integrations, reports, and their "Copilot" chatbot, is on the paid plans.

Pricing:

A limited free plan is available. The main paid plan costs $29 per seat, per month.

How to choose the right free AI chat tool for you

A free plan gets you in the door, but you want to pick a tool that can actually grow with you. Here are a couple of things to think about before you commit:

• Think about the future. Check out the pricing on the paid plans. A tool might be free now, but if you need to upgrade later, will it cost an arm and a leg? Some platforms hide key features behind their most expensive tiers.

• Prioritize integrations. Your chat tool needs to talk to your other software. Make sure it connects with your help desk, CRM, or e-commerce platform. This is where a tool like eesel AI really stands out, since it’s designed to pull information from all your different apps to give the AI context.

• Test the agent experience. When you're testing it out, think about your team. Is the interface easy to use? If it's clunky and confusing, it's just going to create more work for them.

• Understand the "AI". What does the "AI" actually do? Is it just spitting out pre-written answers, or can it actually understand questions and solve problems? Kick the tires on the bot and see if it’s as smart as it claims to be.

Final thoughts: The best free AI chat option grows with you

Picking a free AI chat tool is a great way to start improving your customer support without spending anything. Options like Tawk.to and Freshchat give you a ton of functionality for free, letting you start having real-time conversations with customers right away.

But if you want to see what a true AI assistant can do, it's about more than just answering questions, it's about solving them. That means having an AI that can tap into all your company knowledge to give helpful, accurate answers.

So while you’re checking out the free plans, I’d recommend starting a free trial with eesel AI. In a few minutes, you’ll see the difference between a simple chat window and an AI agent that can actually help customers, cut down on support tickets, and even drive sales. It'll give you a clear idea of what to look for in a tool that can stick with you as you grow.
