## What it is
Proof SDK is an open-source collaborative markdown editor with a realtime collaboration server, provenance tracking, and an HTTP bridge that lets AI agents read and edit documents. It is the self-hostable core of the hosted Proof editor made by Every.

## Use cases
- build a collaborative markdown editor with realtime sync
- let AI agents edit documents through an HTTP API
- track provenance of edits and suggestions in shared documents
- self-host a collaborative writing tool with comments and suggestions
- add agent-driven rewrite operations to a document editor
- run a local collaboration server for document state and presence

## When to choose
- you want a self-hosted collaborative editor with provenance tracking
- you need an HTTP bridge for agents to manipulate document state, marks, and presence
- you want an MIT-licensed alternative to building realtime editing from scratch

## When to avoid
- you need a fully managed hosted product rather than self-hosting
- you need rich-text or WYSIWYG editing rather than markdown
- you need non-Node.js server runtimes
