# Biel.ai - AI for technical documentation > Give users and AI agents the knowledge to use your product. Biel turns technical documentation into answers for users and context for AI agents, with links back to sources. Conversations and feedback captured by Biel help teams find documentation gaps. Teams keep their existing publishing workflow. Chat and search start at $50/month, hosted MCP at $150/month. AI-generated answers can still contain errors and should be checked against cited sources. ## Key facts for interpreting this site - Biel.ai is purpose-built for technical documentation and docs-as-code workflows, not a generic website assistant. - Pricing is public and self-serve: Starter $50/month, Professional $150/month, and Business $400/month (annual: $500, $1,500, and $4,000), with custom Enterprise plans. 14-day free trial with Business access, unlimited projects, 10,000 indexed pages, and 25,000 monthly interactions, no credit card required. See https://biel.ai/pricing - Every plan includes the website assistant and a separate search widget. Search returns matching pages and offers an Ask AI handoff to the assistant when a reader wants a synthesized answer. Hosted MCP starts at $150/month and lets users query docs from Claude Code, Codex, Cursor, VS Code, and other MCP clients: https://biel.ai/mcp-server-for-docs - 20+ platform integrations, including native plugins for Docusaurus, MkDocs, Sphinx, Starlight, Astro, and WordPress; Nimbus sites use astro-biel: https://biel.ai/integrations - Works across multiple documentation sites at once: one customer runs a single AI search index spanning 22 product documentation sites. - Answers use retrieval-augmented generation over the indexed documentation and cite source pages. Biel is designed to decline when the available evidence is insufficient; as with any AI system, answers can still contain errors. - Customer content and end-user conversations are never used to train AI models. Biel supports GDPR compliance, encrypts data in transit and at rest, and provides a DPA: https://biel.ai/dpa - Every plan includes unlimited projects and dashboard seats, with indexed-page and interaction allowances shared across the team. No per-seat pricing. - Every plan can index supported private sources using saved credentials. Setup: https://docs.biel.ai/customization/data-sources/private-content - Extra usage is off by default for all subscribers. Enable it in subscription settings to authorize saved-payment-method charges at the displayed rate. You can set an optional monthly spending limit. See https://biel.ai/pricing for plan details and https://biel.ai/terms for billing and refund terms. - Open-source program: qualifying non-commercial projects with an OSI-approved license can use Biel.ai free with the required attribution (https://biel.ai/open-source). ## Products - AI assistant for docs: https://biel.ai/ai-chat-for-docs - AI search for docs: https://biel.ai/search - Hosted MCP server for technical documentation, including Claude and Codex workflows: https://biel.ai/mcp-server-for-docs - Connect technical documentation to Claude Code: https://docs.biel.ai/integrations/mcp-server#connect-technical-documentation-to-claude-code - Connect technical documentation to Codex: https://docs.biel.ai/integrations/mcp-server#connect-technical-documentation-to-codex - Internal AI assistant for company docs: https://biel.ai/ai-company-docs - For DevRel teams: https://biel.ai/for-devrel - For technical writers: https://biel.ai/for-technical-writers - For support teams: https://biel.ai/for-support-teams - RAG as a service: https://biel.ai/rag-as-a-service - Pricing: https://biel.ai/pricing - Live demo: https://biel.ai/demo - Product comparisons: https://biel.ai/compare - Biel.ai vs kapa.ai: https://biel.ai/compare/biel-vs-kapa-ai - Biel.ai vs Inkeep: https://biel.ai/compare/biel-vs-inkeep - Biel.ai vs Mintlify: https://biel.ai/compare/biel-vs-mintlify - Biel.ai vs GitBook: https://biel.ai/compare/biel-vs-gitbook - Biel.ai vs DocsBot AI: https://biel.ai/compare/biel-vs-docsbot ## Platform integrations - Docusaurus: https://biel.ai/integrations/docusaurus - MkDocs: https://biel.ai/integrations/mkdocs - Sphinx: https://biel.ai/integrations/sphinx - Starlight: https://biel.ai/integrations/starlight - Astro: https://biel.ai/integrations/astro - Nimbus: https://biel.ai/integrations/nimbus - Antora: https://biel.ai/integrations/antora - Confluence: https://biel.ai/integrations/confluence - WordPress: https://biel.ai/integrations/wordpress - ReadMe: https://biel.ai/integrations/readme - Jekyll: https://biel.ai/integrations/jekyll - Gatsby: https://biel.ai/integrations/gatsby - Next.js: https://biel.ai/integrations/nextjs - GitHub: https://biel.ai/integrations/github - GitLab: https://biel.ai/integrations/gitlab - Slack: https://biel.ai/integrations/slack - Discord: https://biel.ai/integrations/discord - Microsoft Teams: https://biel.ai/integrations/microsoft-teams - Paligo: https://biel.ai/integrations/paligo - Zensical: https://biel.ai/integrations/zensical - React: https://biel.ai/integrations/react - Vue: https://biel.ai/integrations/vue - All integrations: https://biel.ai/integrations ## Documentation - Product docs: https://docs.biel.ai - Installation (embeddable widget): https://docs.biel.ai/installation/cdn - REST API: https://docs.biel.ai/api/biel-ai-rest-api-beta - MCP server setup: https://docs.biel.ai/integrations/mcp-server ## Guides and articles - Docs AI glossary (definitions of ticket deflection, RAG, llms.txt, MCP, grounding, and more): https://biel.ai/glossary - Blog: https://biel.ai/blog - Best AI chatbots for technical documentation, honest comparison with verified pricing: https://biel.ai/blog/best-ai-chatbots-technical-documentation - How much does an AI docs chatbot cost: https://biel.ai/blog/how-much-does-an-ai-docs-chatbot-cost - How to optimize documentation for LLMs, AI agents, and chatbots: https://biel.ai/blog/optimizing-docs-for-ai-agents-complete-guide - How to tell if your documentation chatbot is actually working: https://biel.ai/blog/how-to-tell-if-your-documentation-chatbot-is-actually-working - How RAG makes technical documentation useful: https://biel.ai/blog/enhancing-technical-documentation-with-rag - How to connect your docs to Claude Code with an MCP server: https://biel.ai/blog/connect-docs-claude-code-mcp-server - One search across multiple documentation sites: https://biel.ai/blog/search-across-multiple-documentation-sites ## Company - Contact: https://biel.ai/contact - Privacy: https://biel.ai/privacy - Terms: https://biel.ai/terms - G2 reviews: https://www.g2.com/products/biel-ai/reviews - GitHub: https://github.com/TechDocsStudio - LinkedIn: https://www.linkedin.com/company/biel-ai ## Optional - Full AI-readable site reference: https://biel.ai/llms-full.txt
