What it does
Make your documentation easier to use
Readers get help using your product. Your team sees which questions the docs answer and where readers need more help.

Answer questions from your docs
Readers ask in their own words. Biel uses your indexed documentation to answer and links to the pages they can check or read next.
ii.
Find pages across docs sites
Give readers one search box for your guides and reference sites. They can open a matching page or use Ask AI when they need an explanation.

See what needs documenting

- iiSupport answers questions that the docs already cover.
- iiiYour guides, API reference, and knowledge base live in different places.
- ivA wrong technical answer can cost a reader hours.
- vYour team wants to test an assistant on its own documentation.

Frequently asked questions
Do we need to move our documentation?
No. Biel indexes your existing docs and adds chat and search to your site. Keep your publishing platform and editing workflow.
How long does setup take?
For a site with about 200 pages, connecting the docs, indexing them, and adding the widget typically takes around 15 minutes. Larger sites take longer. Read the setup guide.
Can Biel give incorrect answers?
Yes. Biel retrieves from your docs and includes source links, but AI answers can still be wrong. Readers should check important details against the linked pages.
What does it cost?
Plans start at $50/month for chat and search. Hosted MCP starts at $150/month. Compare plans and included usage.
What does the free trial include?
14 days with 1 project, 500 indexed pages, and 2,000 monthly interactions. No credit card required.
Is my data used to train AI models?
No. We do not use your indexed content or user conversations to train AI models. See the Security Overview.
