There are dozens of tools that claim to offer a free chatbot for your website. Some are genuinely free. Some are free for about 20 conversations a month before a hard paywall appears. Some put a competitor's branding on your site and call that a fair trade. And a few are actually good.
This guide cuts through the noise. We tested five of the most widely used options, looked at what each free plan actually includes, and wrote up honest pros and cons for each — so you can get a free AI chatbot on your website without unpleasant surprises two weeks in.
What Makes a Free Chatbot Actually Worth Using?
Before comparing tools, it helps to know what "free" really means in this market. These are the questions you should ask about any free tier:
- How many conversations per month does the free plan include? Anything under 30 is essentially useless for a real website. Look for at least 50–100.
- Is the AI genuinely trained on your website? Some "free chatbots" are just rule-based scripts that require you to manually program every question and answer. That's not an AI chatbot — that's a decision tree from 2015.
- Is there branding on the widget? Some tools put their own logo and "Powered by [Tool]" on your chatbot. That looks unprofessional and may undermine visitor trust.
- How easy is installation? A free tool that requires a developer to install is not really free — it has a hidden cost. Look for a simple copy-paste embed code.
- Does it work on your platform? WordPress, Shopify, Wix, Squarespace, plain HTML — the chatbot should work on whatever you use.
With those criteria in mind, here are the five best options for a chatbot for website free in 2026.

The 5 Free Chatbots: Full Reviews
InstantBot
Best Overall FreeWhat's free: 50 AI-powered conversations per month. The bot automatically crawls your website and learns your content — no manual setup of questions and answers. One-line embed code. No credit card required. No branding on the widget. Works on any website platform.
What's limited: At 50 conversations per month, you'll hit the cap if you have heavy traffic. Upgrading to 1,000 conversations costs $29/month. The free plan also supports one chatbot (one website URL), which is enough for most small businesses.
What sets InstantBot apart from every other free option is that setup takes about two minutes. You enter your URL, the crawler reads your site, and the chatbot is ready to embed. It understands natural language — so a visitor can ask the same question ten different ways and still get an accurate answer. There's no scripting, no flow-building, no drag-and-drop decision trees to wrestle with.
For businesses that want to add a free AI chatbot to their website without technical friction, this is the most frictionless path available. If you want someone else to handle the setup entirely, there's also a done-for-you setup service.
Pros
- Genuinely free — no card needed
- Real AI trained on your website
- No branding on the widget
- Works on any platform
- Setup in 2 minutes
- Natural language understanding
Cons
- 50 conversations/month cap on free
- One chatbot per free account
Tidio
Good, With CaveatsWhat's free: Tidio's free plan includes live chat (unlimited conversations with a human agent), plus 50 AI Lyro conversations per month. You can train the AI on your FAQ content manually, or import from a URL. The interface is polished and there are integrations for Shopify, WordPress, and Wix.
What's limited: The AI on the free plan is capped at 50 conversations — same as InstantBot. However, Tidio puts its own branding ("Powered by Tidio") on your chat widget unless you pay for a higher plan. The setup process is also noticeably more involved: you're building conversation flows and configuring automation rules, which takes time if you're not technical.
Tidio makes more sense if you want a hybrid solution — live chat for when you're available, AI for when you're not — and you don't mind the setup complexity or the branding. For pure AI chatbot functionality without the extras, it's overkill.
Pros
- Live chat + AI in one tool
- Good Shopify integration
- Polished UI
- 50 AI conversations free
Cons
- "Powered by Tidio" branding
- Complex setup for non-technical users
- AI features cost more to unlock fully
Chatbase
Very Limited Free TierWhat's free: Chatbase lets you build an AI chatbot trained on your content — you can upload documents, paste text, or provide a URL for it to crawl. The free plan includes one chatbot and 20 AI message credits per month.
What's limited: Twenty messages a month is genuinely not enough for a real website. A single customer with three follow-up questions uses 15% of your monthly quota. The free plan also includes Chatbase branding on the widget and limits you to one chatbot. Paid plans start at $19/month for 2,000 messages.
Chatbase is better suited as a tool for developers and builders experimenting with AI chatbot concepts than as a free production solution for a small business website. It's worth knowing about, but the 20-message cap makes it impractical for most real use cases.
Pros
- Trains on documents and URLs
- Good customization options
- Developer-friendly API
Cons
- Only 20 messages/month free
- Chatbase branding on widget
- Not practical for real traffic
tawk.to
Free Live Chat, Not AIWhat's free: tawk.to is genuinely, completely free — no conversation caps, no artificial limits. You get a live chat widget you can add to any website. Unlimited agents, unlimited chats. It's the most generous free tier on this list in terms of raw volume.
What's limited: tawk.to is not an AI chatbot. It's a live chat tool, which means someone has to be on the other end to respond. If no one is available, visitors see you as offline. There is a basic chatbot feature (called "Shortcuts") for canned responses, but it's rules-based and not AI-powered. The widget also carries tawk.to branding — you can pay $19/month to have it removed. If you want a chatbot that answers questions automatically when you're not around, tawk.to doesn't do that on the free plan.
Pros
- Truly unlimited free live chat
- Solid mobile app for agents
- Good for high-volume live support
Cons
- No AI — requires human agents
- tawk.to branding on widget
- Offline when no agent is available
- Not a replacement for AI automation
HubSpot Chat
Free if You Use HubSpotWhat's free: HubSpot's free CRM includes a live chat widget and basic chatbot builder. You can create simple conversation flows — greet visitors, capture email addresses, route to a team member — and all conversations are logged in the HubSpot CRM automatically. Unlimited live chat conversations are included.
What's limited: HubSpot Chat is not an AI chatbot on the free plan. The "chatbot" is a flow builder — you manually create decision trees with pre-set responses. There's no natural language understanding. If a visitor asks something you didn't script, the bot doesn't handle it gracefully. AI-powered features require HubSpot's paid plans, which start at $20/month per user and scale up significantly. The widget also carries HubSpot branding on the free tier. The real value of HubSpot Chat is only apparent if you're already using or planning to use HubSpot as your CRM — as a standalone free chatbot for a website, it's cumbersome.
Pros
- Integrates natively with HubSpot CRM
- Unlimited chats on free tier
- Good for lead capture flows
Cons
- No AI on free plan
- Manual flow building required
- HubSpot branding on widget
- Overkill unless you use HubSpot CRM
Which Free Chatbot Should You Choose?
Here's the honest decision guide:
- You want an AI chatbot that answers questions automatically, with minimal setup: Use InstantBot. It's the only option that is genuinely free, has no branding watermark, uses real AI trained on your website, and takes two minutes to set up.
- You want live chat plus some AI, and you don't mind setup complexity: Tidio is worth a look. Just be aware the branding stays until you pay.
- You're a developer building something and want to experiment with AI chatbot technology: Chatbase has a good API, but the 20-message free cap means you'll need to pay quickly in any real deployment.
- You want live chat and have team members available to respond: tawk.to is unbeatable for pure live chat volume on the free tier. It just isn't an AI chatbot.
- You're already using HubSpot as your CRM: HubSpot Chat is the obvious choice because everything lives in one place. Otherwise, it's more friction than it's worth.
How to Get Started with a Free AI Chatbot in 5 Minutes
If you've decided InstantBot is the right fit, here's what getting your free chatbot for your website actually looks like:
- Go to instantbot.app and create a free account. No credit card required.
- Enter your website URL. InstantBot's crawler visits your site and reads your pages — about page, FAQ, product descriptions, contact info, hours, whatever is publicly accessible.
- Copy your embed code. One line of JavaScript that you paste into your website before the closing
</body>tag. - Paste it into your site. On WordPress, use the "Insert Headers and Footers" plugin. On Shopify, it goes in theme.liquid. On Wix, use Custom Code. On Squarespace, use Code Injection. On plain HTML, paste directly before
</body>. - Test it. Reload your site and ask the chat widget a question a real customer would ask. You should get an accurate, natural-language answer within seconds.
That's it. No conversation flows to design. No questions and answers to manually enter. No developer needed.
If you'd rather not handle any of the setup yourself, check out the done-for-you setup service — everything is handled for you and your chatbot is live the same day.
Frequently Asked Questions
Is there a truly free AI chatbot for websites?
Yes. InstantBot offers 50 AI conversations per month on its free plan with no credit card required and no branding on the widget. That's enough for a small business site to prove out the value before deciding whether to upgrade.
What happens when I hit 50 conversations on the free plan?
The chatbot pauses for the rest of the month. Visitors will still see the widget, but it won't respond until the next billing cycle resets your count — or until you upgrade. You'll get an email notification before you hit the limit so you can plan accordingly.
Do I need a developer to install a free chatbot?
No. All five tools on this list use a simple copy-paste embed code. If you can add anything to your website — a Google Analytics tag, a Facebook Pixel — you can install a chatbot. WordPress users can use the "Insert Headers and Footers" plugin to avoid editing theme files entirely.
Will the free chatbot actually understand what my visitors ask?
InstantBot and Chatbase use real large language models, so they understand natural language and interpret questions accurately even when phrased in unexpected ways. tawk.to and HubSpot Chat's free bots are rule-based and will struggle with anything you didn't script explicitly.
Can I upgrade later if my traffic grows?
Yes — every tool on this list has paid tiers. InstantBot's first paid plan is $29/month for 1,000 conversations. The free tier is designed as a genuine starting point, not a crippled trial.
