Biel.ai

AI for Technical Documentation That Has to Be Right

Biel.ai is a specialized AI documentation assistant built for technical software companies whose customers depend on accurate, accessible documentation. Unlike generic chatbots, Biel parses technical documentation as structured information—understanding OpenAPI specs, code blocks, configuration examples, and error messages—to deliver precise answers rather than just surface-level search results.

Intelligent Documentation Understanding

Biel reads documentation the way developers do, treating technical content as structured data rather than flat text. It recognizes endpoints, parameters, return types, and code structures, enabling it to answer questions in users' natural language while mapping to how documentation is organized. When users ask "why am I getting a 401," Biel translates that to the relevant authentication documentation and returns the specific answer, not just a list of pages.

Key Features & Capabilities

• Multi-source indexing: Ingests documentation from Docusaurus, MkDocs, Sphinx, GitHub, and other sources into a unified knowledge base
• Embeddable widget: Deploy on docs sites with one line of code, fully themeable to match your brand
• MCP server integration: Makes your documentation queryable from Claude, Cursor, Copilot, Windsurf, and other MCP-compatible AI tools
• Native chat apps: Pre-built integrations for Slack, Microsoft Teams, and Discord for internal knowledge access
• Production REST API: OpenAPI 3.0-compliant API for embedding Biel into your own products or workflows
• Content gap analysis: Tracks unanswered questions to identify missing or unclear documentation before they generate support tickets
• AI-powered search: Goes beyond keyword matching to understand intent and return relevant answers

Who It's For

Biel is designed for teams where documentation is mission-critical: developer tools, API platforms, technical SaaS products, and enterprise software companies. If your support team answers the same documented questions repeatedly, your docs span multiple locations, or your users catch hallucinated AI answers immediately, Biel provides the accuracy and integration depth generic solutions can't match.

Deployment & Integration

Deploy in minutes, not months. The embeddable widget installs with a single line of code. Native team chat apps install with one click. The REST API and MCP server enable custom implementations. Every deployment method works from the same indexed source of truth, ensuring consistency across all user touchpoints. Start with a 14-day free trial—no credit card required.
