AI-powered docs
for every API
REST, GraphQL, WebSocket, gRPC — one platform that generates beautiful docs, answers developer questions with AI, and keeps everything in sync with your code.
Free for up to 50 pages · No credit card required
Built for teams shipping APIs, SDKs, and developer tools
Everything your docs need. Nothing they don't.
One platform replaces your docs framework, API reference generator, search engine, and AI chatbot.
Code Annotations
Add @stx tags to your code. We parse them on every push and keep your docs perfectly in sync.
AI Assistant
An AI that answers questions from your docs with citations. It knows what's documented — and tells you what's missing.
API Playground
Interactive 'Try It' for every endpoint. Users test your API directly from the docs — no Postman needed.
Drift Detection
CI checks detect when code changes outpace docs. Get alerts before documentation goes stale.
Analytics
Page views, search queries, AI questions, and content health scores. Know exactly which docs need attention.
One-Click Migration
Switch from Mintlify, ReadMe, Docusaurus, or GitBook in minutes. Automatic format conversion.
Three steps to docs that never go stale
Annotate your code
Add @stx tags to your functions, endpoints, and types.
Push to Git
On every push, we parse annotations, compile MDX, generate API references, embed for AI, and deploy — in seconds.
Ship beautiful docs
Your site goes live with full-text search, AI assistant, API playground, and a design that rivals Stripe's docs.
More features. Lower price.
