Biel.ai is AI for docs that have to be right. It turns technical documentation into an AI assistant that answers user questions instantly, reduces support tickets, and reveals content gaps.
Biel parses OpenAPI specs, code blocks, and error messages as structured information, not flat text, and returns source-cited answers drawn only from your verified content. One indexed source of truth, four ways to query it: an Ask AI widget and AI search for Docusaurus, MkDocs, Sphinx, Starlight, Antora, Next.js, WordPress, and any HTML site; a hosted MCP server for Claude, Cursor, and GitHub Copilot; native Slack, Discord, and Microsoft Teams apps; and a REST API with RAG-as-a-Service.
Analytics show what users searched, where they gave up, and which pages need work. Multilingual out of the box, AES-256 encryption, GDPR compliant, EU-hosted, bring your own keys. Self-serve, 14-day free trial, live in 15 minutes. Used in production by ScyllaDB, Katalon, Talon.one, Tezos, and CrazyGames.
