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 -->

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 built for the people who own that experience: technical writers, docs engineers, DevRel teams, and support teams.
If two or more of these describe you, keep reading. If none do, Biel probably isn’t the right fit, and that’s fine.
