Best Free AI Chatbot Builders for Your Website (2026)

A website chatbot can answer common questions from your own pages and documents. Free plans limit messages, bots or data sources, and some keep their branding. Test with your real FAQs and make sure the bot can hand off to a person when it is unsure.

Disclosure: some Visit links may be affiliate links, and we may earn a commission at no extra cost to you. Details come from official pricing and product pages, last reviewed 2026-10-15; this is not a hands-on test. Confirm current limits with the provider.

What to check before you choose

  • How many messages, bots or data sources does the free plan allow?
  • Can the bot answer only from your approved content?
  • Can it hand a conversation to a human?
  • Does the widget carry the vendor's branding on the free plan?

How we chose: tools listed here have an active product, a free plan or free tier, and pricing we could confirm from the provider. Retired or paid-only tools are left out automatically.
