Key Takeaways
- Most "free chatbots" either have no AI or severely limit AI usage on free plans.
- FutureBase offers the most generous free AI chatbot: 600 credits/month with real AI trained on your docs.
- Tawk.to is the best free option if you don't need AI (unlimited free live chat with humans).
- Free tiers are a great way to test before committing—but understand the limitations before choosing.
Adding an AI chatbot to your website used to cost hundreds per month. In 2026, several platforms offer genuinely useful free tiers. But "free" means different things—some include real AI, others are just basic chat widgets.
Here's an honest breakdown of the best free options.
1. FutureBase — Best free AI chatbot overall
Free plan includes: 600 AI credits/month, auto-training on your website, 10 additional URLs, 10 FAQs, custom file upload, 1 team member
AI quality: High. Auto-trains on your website and docs. Contextual understanding—not keyword matching. Hallucination scoring built in. 50+ languages.
How to add it: One script tag on any HTML, WordPress, or Next.js site. Takes about 5 minutes.
Limitations on free:
- 600 credits/month (roughly 600 AI responses)
- 1 team member
- FutureBase branding on widget
- No 3rd-party integrations
- No analytics dashboard
Why it stands out: FutureBase is the only free chatbot that auto-trains on your website, provides real AI-powered responses, and includes a feedback collection system—all on the free plan. Most competitors either have no AI on free tiers or limit you to 50–100 conversations.
Upgrade path: Hobby at $29/month adds 30,000 credits, analytics, integrations, and 3 team members.
2. Tawk.to — Best free live chat (no AI)
Free plan includes: Unlimited agents, unlimited chat history, knowledge base, ticketing, real-time visitor monitoring
AI quality: None. Tawk.to has no AI features. Every message is handled by a human.
How to add it: Script tag on your website.
Limitations on free:
- No AI—humans must respond to every message
- Tawk.to branding ($19/month to remove)
- When no agents are online, visitors see an offline form
Why it stands out: Tawk.to is genuinely 100% free with no conversation limits. If you have team members available to respond and don't need AI, it's hard to beat. Real-time visitor monitoring shows who's on your site and which pages they're viewing.
Upgrade path: Paid add-ons for branding removal ($19/month) and hired agents ($1/hour).
3. Chatbase — Best free plan for AI customisation
Free plan includes: Limited AI message credits, 1 chatbot, basic customisation

How to add it: Embed code or API integration.
Limitations on free:
- Very limited message credits (approximately 100/month)

Why it stands out: Even the free plan lets you choose AI models and customise chatbot behaviour. Good for testing whether an AI chatbot fits your use case.

4. Tidio — Best free chatbot for Shopify
Free plan includes: 50 Lyro AI conversations/month, basic live chat, chatbot flow builder

5. Freshdesk — Best free helpdesk (AI as add-on)
Free plan includes: Up to 10 agents, email and social ticketing, knowledge base

Limitations on free:
- No AI on free plan at all

7. HubSpot — Best free chat with CRM
Free plan includes: Basic live chat, email, forms, shared inbox, HubSpot CRM

Honest advice on free chatbots
Free tiers are great for testing, but they have real limitations:
- AI conversation limits (50–600/month) might not be enough if you get significant traffic.
- Branding on every chat widget signals "budget tool" to your customers.
- Missing integrations mean you'll manually manage what paid plans automate.
If your website gets more than a few hundred visitors per month, you'll likely outgrow free plans within weeks. Use the free tier to validate the approach, then upgrade to the tool that best fits your workflow.
FutureBase's free tier is the most generous for AI—600 credits/month with auto-training on your website. It's the best way to test AI customer support without spending a dollar.
