Documentation.AI

Self-updating AI documentation, knowledge bases and API references

AI Documentation Agent and automations

Triggered by a PR merge or on a daily/weekly/monthly schedule, the agent reads code changes, tickets and feedback, drafts page updates and returns a summary and diff for approval before anything goes live.

Web editor plus docs-as-code

Write in a Notion-style visual editor with slash commands and drag-and-drop blocks, or in Markdown/MDX with Git branches, pull requests, preview builds and two-way sync — same docs, same review flow.

AI Assistant and MCP servers

Embed a cited, confidence-scored Ask AI assistant in your docs, and expose content to external AI tools via Reader and Authoring MCP servers plus llms.txt generation.

API references and playground

Import OpenAPI specs to auto-generate API documentation with a live try-it console so developers can call endpoints straight from the docs.
