Why teams use Biel.ai for AI Chatbot
Biel.ai is an AI chatbot built specifically for technical documentation. Rather than wrapping a search index in a chat UI, it parses OpenAPI specs, code blocks, configuration examples and error messages as structured information, so it can answer developer questions like "why am I getting a 401" with the actual answer instead of a link to a page. It plugs into existing doc stacks — Docusaurus, Sphinx, MkDocs, Starlight, Hugo, Antora — with an embeddable widget, and also surfaces answers in Slack, Microsoft Teams and Discord, through an MCP server (Claude, Cursor, Copilot, Windsurf), or via a REST API. A standout feature is content-gap analytics: every unanswered question is logged so documentation teams can see what users tried to find and which pages need work. It's used in production by teams at ScyllaDB, Katalon, Talon.one, Tezos and others, and offers a 14-day free trial with self-serve setup.
