// What Lumen does

Designed for the
long-form writer.

Six features, all of which exist because writers asked for them. Anything we couldn't do well, we left out.

Distraction-free

Type. That's it. Hide the sidebar with one keystroke and the app disappears entirely.

Markdown native

Write in markdown, render in real-time. Export as plain text, HTML, or PDF.

Instant sync

End-to-end encrypted across all your devices. iCloud, Drive, or self-hosted.

Focus mode

Spotlight just the line you're writing. Everything else fades. Beautiful.

Keyboard-first

Every action has a shortcut. The mouse is for tourists.

AI rewrites

Highlight a sentence, hit โŒ˜K, and Lumen offers cleaner versions. Always optional.

// Built for the keyboard

Faster than
your fingers.

The mouse is optional. Every important action has a single-key or โŒ˜+key shortcut. Memorize ten of them and you'll never go back.
