See why it’s different

One document. Two honest views.

Rendered when you want to write.
Raw when you need the truth.

Most editors make you pick a side. Munin gives you editable rendered and source modes, switching in place while preserving your position.

Same document. Same position.

Small app. Serious editor.

Built for files, not a platform.

01

Native speed you can measure

Type at full speed in a 50,000-word document. Munin responds in milliseconds, opens quickly, and stays out of your battery.

1ms median keystroke response
02

Your folder is the workspace

Open a folder and start. Keep several folders in titlebar tabs. No vault, index database, proprietary library, or sidecar files.

03

Ready for files that change

Git pulls, agents, and other editors can update a document while Munin preserves your cursor and scroll. Conflicting local text is kept in macOS file versions.

04

Tokens, not just words

See the token count alongside words and characters before your Markdown heads to an LLM.

05

Plain files. Fully local.

No account and no telemetry. Use Git, iCloud Drive, Dropbox, or nothing at all.

06

Know where you are

Source-accurate line numbers stay visible in rendered mode. An outline rail turns headings into a map you can navigate.

07

Smaller than a photo

The complete app is about 10 MB. It installs in seconds because macOS already provides the system frameworks it needs.

No “minimal” excuses

The rest of the editor is here too.
