In their own words
Documentation.AI
Documentation.AI combines an AI documentation agent, review workflows, publishing, and AI access for technical documentation. Teams can write in a visual web editor or use Markdown and MDX in Git repositories with pull-request previews. OpenAPI specifications generate API reference pages with request and response examples plus a live playground. Agent and workflow changes arrive as drafts or commits for review instead of publishing automatically. The platform includes an in-document assistant with cited answers, a Reader MCP server, and generated llms.txt. GitHub, GitLab, Jira, and Confluence can supply context, while analytics and chat integrations include Google Analytics 4, PostHog, Intercom, and Crisp. Documentation may be public, password-protected, or private with JWT or OAuth 2.0; SAML/OIDC SSO and SCIM are Enterprise features. AI work pauses when credits run out until the next cycle or a top-up, with no overage billing stated. Starter is free; Standard costs $55 a month billed yearly, and Pro costs $159 a month billed yearly.
