Changelog.
A smarter assistant for your documentation
The assistant uses tools to find more context, read the page you're viewing, and ask follow-up questions when it needs more detail.
Reuse credentials across your team's sources
Save named credentials once, reuse them across sources and projects, and connect private websites, repositories, spaces, and videos on every plan.
Add YouTube, Vimeo, and Q&A sources to your assistant
Connect tutorial videos or write answers directly in Biel.ai, so your assistant can use knowledge that is missing from your published docs.
Browser agents can now use your docs with WebMCP
Let browser agents search and read your documentation through the Biel widget with WebMCP, available on plans that include MCP.
GPT-6 and Claude 5.5 are now available
Choose GPT-6 Luna, GPT-6.1 Sol, Claude Haiku 5.5, or Claude Sonnet 5.5 for your Biel.ai chatbot, with options for every plan.
Let AI assistants search and read your docs
Claude and other AI assistants can find relevant information in your docs and read full documents when they need more context.
See what your assistant is doing
Follow your assistant's progress as it searches documentation and writes an answer, with a choice of a progress spinner or classic loading dots.
See the source beside each answer
Biel.ai now places numbered source links beside supported claims in chatbot answers, so readers can check the original documentation as they read.
Ask your chatbot to draw a diagram
Ask for a flowchart, sequence, or architecture diagram and Biel.ai draws it in the web chatbot from your documentation, alongside a written answer.
Biel.ai now reads images in your documentation
Biel.ai describes screenshots, diagrams, and charts during a crawl, then indexes that text with the surrounding documentation page.
Pass chat context to your action URLs
Send a chatbot conversation ID, dashboard link, or the visitor's latest question to the form or tool an action opens.
Native Biel.ai plugins for six documentation stacks
Install Biel.ai through native packages for Docusaurus, MkDocs, Sphinx, Starlight, Astro, and WordPress.
Create API keys that only reach one project
Limit a Biel.ai API key to one project so an integration cannot read or manage the rest of your team's projects.
GPT-5.6 Luna and Terra are now available
GPT-5.6 Luna is now the default on every plan; GPT-5.6 Terra is available on Business plans and above.
API v2 is here, and it can do everything the dashboard can
API v2 brings analytics, project and team management, chat history, and every source type. Available on Business and Enterprise plans.
Claude Sonnet 5 is now available
Claude Sonnet 5 is available for Biel.ai chatbots on Business plans and above.
Your chatbot can now book calls and open tickets
Actions are live: point a button in the chatbot's answer at any URL: Calendly, Stripe, your support portal. Four fields, two minutes.
Ask Biel.ai from Slack, Teams, and Discord
Three new places to ask: @mention or DM the bot in Slack, Microsoft Teams, or Discord, with per-channel context and a /clear reset.
See the questions your docs can't answer
Content Gaps clusters what users ask, then ranks the questions your docs don't cover by frequency, so you know what to write next.
Export your conversations in bulk, no API needed
Export your chatbot conversations in bulk for offline analysis, audit trails, and compliance, straight from the dashboard, no API needed.
Think mode: reasoning for questions that aren't a lookup
A reasoning mode for multi-step questions. Auto, Instant, or Think: the chatbot reasons before it answers instead of just retrieving.
Connect your Confluence Cloud spaces as a source
Index Confluence Cloud spaces with auto-sync, for internal docs, support KBs, and hybrid public and internal setups in one chatbot.
Train a Custom GPT on your docs with Biel.ai
Build a ChatGPT Custom GPT that queries your Biel.ai knowledge base live over the API, so answers stay current and cited without re-uploading files.
Refer a team, get 3 months free
Know a team that needs better docs? Introduce them to us. When they subscribe, your billing is paused for 3 months. They get 1 month free to try.
Your chatbot now reads OpenAPI specs directly
Point the chatbot at an OpenAPI spec and every endpoint, parameter, and schema is indexed automatically, with no crawling your API reference.
Connect Git repositories as a documentation source
Index public and private repos alongside your written docs, so answers cite the actual code and not just the prose around it.
GPT-5 and Claude 4 are now available
Power your chatbot with GPT-5 or Claude 4 on Business plans. Pick the model that fits your docs and your budget in one dropdown.
AI Assistant v2 sticks to your docs
A redesigned default prompt keeps answers inside retrieved context, so you get fewer hallucinations and an honest "I don't know" when docs fall short.
Query your docs from VS Code, Cursor, and Claude Desktop
The Biel.ai MCP server connects your docs to the editor, so developers ask questions and get answers without leaving VS Code, Cursor, or Claude Desktop.
Choose the AI model behind your chatbot
Pick the model that runs your docs chatbot across the GPT and Claude families: fast ones for live answers, advanced ones for technical depth.
Shape your chatbot with custom prompts
Set priorities, flag what the docs don't cover, and control tone with a custom prompt that steers how your chatbot answers every question.
Built-in data privacy controls
Strip PII automatically, disable IP logging, and require users to accept terms before they chat, so your deployment meets compliance needs.
Upload PDF, Word, and Excel files as sources
Drop a file in as a documentation source and the chatbot answers from it: PDF, Word, Excel, and Markdown, no website required.
