FAQ Widget — AI-powered embeddable FAQ assistant

Grounded answers

The assistant answers only from your knowledge base. If the answer isn't there, it says so — no hallucinations.

Embed anywhere

One <script> tag. Works on any site — WordPress, Webflow, static HTML — as a sandboxed iframe.

Instant setup

Paste your KB text, copy the snippet, paste into your site. No database, no config files.

Rate limited

50 questions per IP per day. The open CORS policy is a deliberate trade-off — rate limiting is the control.

Playground

Edit your KB, ask questions, copy the snippet.

The KB on the left is editable. Your questions go to the live POST /api/ask endpoint — results come back grounded in whatever text you’ve pasted.
