Hanji _{한지 韓紙}

Capture the thought.

Hanji is a light, local-first Markdown text editor.

Principles

• Light by default: fast startup, minimal chrome, and a quiet editing surface.
• Local first: offline editing is the core workflow, not a fallback.
• Markdown native: plain text files should remain readable outside the app.
• Extensible by design: plugins should be easy to author, inspect, install, and remove.
• Collaboration when online: real-time editing should feel optional, direct, and unobtrusive.

Getting Started

Rust core checks:

cargo test --workspace --exclude hanji

GPUI desktop app:

make app
make app FILE=/path/to/note.md
