Ships every feature request before the week is out.
“The support at biel.ai is outstanding. They're always fast and helpful, and they turn our feature requests into reality in no time.”
When your product depends on documentation that customers actually use, you need more than a generic chatbot. Biel reads your docs the way your users would, answers in their words, and shows you what's missing.
To enable dark mode for Biel.ai on your website, follow these steps:
data-theme="dark" to the <html> tag.<html data-theme="dark">
<!-- Your existing HTML content -->
</html>This change activates the dark mode styling for Biel.ai…
Used by teams that take their documentation seriously
Most "AI for docs" tools wrap a search index in a chat UI. That works for a help center. It doesn't work when your customers are engineers and your docs are how your product gets adopted.
Biel parses OpenAPI specs, code blocks, configuration examples, and error messages as structured information, not flat text. A generic chatbot sees a paragraph. Biel sees an endpoint, a parameter, a return type.
Users don’t ask "what’s the syntax for the auth endpoint." They ask "why am I getting a 401." Biel translates between how users think and how your docs are organized, and returns the answer, not the page.
Every unanswered question is a content gap. See what users tried to find, where they gave up, and which pages need work. Real signal for your next sprint, before tickets reach your team.
If your customers depend on your documentation to do their job, generic chatbots aren't enough. Biel is for the teams who already know that.
If two or more of these describe you, keep reading. If none do, Biel probably isn’t the right fit, and that’s fine.
Three quotes from the people running Biel in production.
“The support at biel.ai is outstanding. They're always fast and helpful, and they turn our feature requests into reality in no time.”
“Super easy to get started, reads all our sites without trouble, and helps us learn what questions our users ask.”
“Biel.ai has been one of those great examples of low effort, high impact tasks. Easy to set up, yet the positive effects are felt immediately.”
One indexed source of truth. Four production-ready ways for users to query it: on your docs site, in their AI tools, in your team's chat, or built into your own product.
Drop the embeddable widget into Docusaurus, Sphinx, or any HTML site. Themeable to your brand, native to your stack, ready in 15 minutes.
Your documentation becomes queryable from Claude, Cursor, Copilot, Windsurf, and any MCP-compatible tool. Developers stop copy-pasting from your docs into their AI.
Native Slack, Discord, and Microsoft Teams apps. One-click install. Mention the bot in any channel and it answers from your indexed docs, with sources cited.
Production REST API with OpenAPI 3.0 spec, real auth, rate limits that scale. Embed Biel inside your product, build a custom internal tool, or wire it into any workflow.
# Ask anything, programmatically curl app.biel.ai/api/v1/chats/ \\ -H "Authorization: Token ..." \\ -d '{"message":"How do I auth?"}'
