Mintlify is a documentation platform that helps companies build, host and maintain developer and API documentation, with AI features that keep docs accurate and easy for both people and AI agents to read.
Teams write docs in MDX stored in Git or edit them in Mintlify's web editor, and Mintlify publishes a fast, searchable site. Many well-known developer companies use it for public docs, and newer features like an AI writing agent and an MCP server make documentation usable by AI assistants too.
Key features
- Docs-as-code with MDX files synced from Git, plus a web editor
- Interactive API playground generated from OpenAPI specs
- Custom domains and authentication for private docs
- MCP server so AI tools can query your documentation
- AI Assistant that answers reader questions from your docs
- Writing agent and Autopilot that propose updates when your product changes
- Analytics, preview deployments and admin APIs on Pro
Who it's for
Mintlify is built for API-first companies, developer tool startups and platform teams that need professional public documentation without building a docs site themselves.
Common use cases
- Publishing API references and SDK guides
- Moving off a self-built Docusaurus or legacy docs site
- Keeping docs in sync with product changes using AI
- Making docs accessible to AI coding assistants via MCP
