What is OpenMarkdown?
OpenMarkdown is a feather-light, local-first Markdown editor built for you and your agent. It enables real-time co-editing between human and AI, with a native Rust core for instant startup and full control over your plain .md files.
A markdown editor you and your agent co-edit
Core Features
Local-first: every note stays a plain .md on your disk, no cloud lock-in
Agent-native collaboration: you and your agent edit the same file simultaneously
Instant startup: native Rust core opens the window before you let go of the mouse
Byte-for-byte preservation: never reflows, trims, or reformats your text
One-tap three modes: live preview, plain source, clean reading
No telemetry: nothing phones home, your agent reads the same file on the same disk
