Best Free AI Chatbot Tools You Can Use Today
Not every business has the budget to invest in premium AI chatbot software right away. The good news? Several excellent chatbot platforms offer free plans or generous trials that let you automate customer conversations without spending a dime. We've tested the most popular free options so you don't have to.
Here are six free AI chatbot tools worth trying in 2026 — each with different strengths depending on your business needs.
1. Tidio — Free Plan with AI Conversations
Free tier: 50 AI conversations/month, live chat, basic chatbot flows
Tidio's free plan is surprisingly capable. You get their Lyro AI assistant, which can answer customer questions using your knowledge base, plus a drag-and-drop chatbot builder for simple automation flows. It integrates with Shopify, WordPress, and Wix out of the box. For small businesses just getting started with AI chat, it's the best free starting point.
2. HubSpot Chatbot — Free CRM Integration
Free tier: Unlimited chatbot flows, built into HubSpot CRM (free)
HubSpot's chatbot builder comes bundled with their free CRM, making it a no-brainer if you already use HubSpot or want a CRM alongside your chat. Build custom bot flows that qualify leads, book meetings, and route conversations to the right team member. The AI capabilities are more limited than dedicated chatbot tools, but the CRM integration is unmatched at this price point — free.
3. Botpress — Best Open Source Option
Free tier: Self-hosted (unlimited), cloud free tier available
Botpress is the go-to choice for developers and technical teams who want full control. It's open source, so you can self-host it for free with no conversation limits. The visual flow builder is powerful, and it supports GPT-powered knowledge answering natively. If you have the technical chops to deploy it, Botpress gives you enterprise-grade chatbot capabilities at zero cost.
4. ChatBot.com — 14-Day Free Trial
Free tier: 14-day trial, no credit card needed
ChatBot.com doesn't have a permanent free plan, but their 14-day trial gives you full access to the platform's best-in-class visual builder. Create complex conversation flows with drag-and-drop, train the AI on your website content, and test it with real customers. It's enough time to know whether the tool is right for your business before committing.
5. Tawk.to — Free Forever
Free tier: Completely free, unlimited agents, unlimited chat history
Tawk.to is the only live chat platform that's 100% free with no conversation caps and no agent limits. The chatbot capabilities are more basic than AI-first platforms — think canned responses and keyword triggers rather than GPT-powered conversations. But for businesses that primarily want live chat with some automation, you literally can't beat the price.
6. Crisp — Free Plan for Small Teams
Free tier: 2 seats, live chat, basic chatbot, shared inbox
Crisp's free plan gives small teams a taste of their all-in-one platform: live chat widget, basic chatbot automation, and a shared inbox. The AI features are reserved for paid plans, but the free tier is solid for startups that want a clean, modern chat experience with room to grow. When you're ready, upgrading unlocks their MagicReply AI and knowledge base.
