AI chatbot for websites — powered by GPT, Claude, or Gemini
Choose your favorite model, give it your pricing page and FAQ, and let it answer customer questions 24/7. Human takeover happens automatically when you reply.
Why teams pick this
Bring your own model
Switch between Gemini 2.5 Flash, GPT-4o, GPT-4o mini, Claude Sonnet, or Claude Haiku from a dropdown. Use your own API key.
Trained on your URLs
Add up to 10 URLs (pricing, FAQ, docs). The AI scrapes them daily and uses the cleaned text as context for every reply.
Seamless human handoff
The AI handles the easy stuff. The moment you send a manual reply, the AI pauses for that conversation automatically.
Per-visitor instructions
Use webhooks to fetch personalized instructions for each visitor based on plan, account ID, or any client-side data.
How it works
Enable AI auto-reply
Open Chat → AI Agent and toggle it on. Pick a model and paste your API key.
Add knowledge URLs
Drop in your pricing page, FAQ, and docs URLs. FloatMessage scrapes them and refreshes daily.
Set instructions
Write a short system prompt (your tone of voice, what to do when stuck) and you're live.

Frequently asked questions
Which AI models are supported?
Gemini 2.0 Flash, Gemini 2.5 Flash, GPT-4o, GPT-4o mini, Claude Sonnet 4.5, and Claude Haiku 4.5. Switch between them anytime.
Do I need my own API key?
Yes. You bring an API key from Google, OpenAI, or Anthropic. This keeps usage costs transparent and gives you full control.
How does it learn about my product?
Add URLs to your knowledge sources. FloatMessage scrapes them, extracts clean text, caches for 24 hours, and includes it in every AI prompt.
Will the AI hallucinate?
We instruct the model to only answer from the provided knowledge and to say 'I'm not sure, let me get a teammate' when it doesn't know.
Can I limit the number of AI replies per conversation?
Yes. Set a max-interactions cap so the AI hands off after N exchanges if the visitor still needs human help.
