You were three chapters in.

Then you hit a word you didn't know. New tab. Translator. Notes app. By the time you got back, you'd lost your place — and your flow.

One shortcut.
Stay in the book.

Leafy lives in your menu bar. Press ⌥A, draw a box around any word on screen, and get the definition — without leaving the page.

No copy-paste, no new tab. Draw a selection around any word on screen — in any app, any language.

Pronunciation, part of speech, full definition — and what the word means in the exact sentence you're reading.

Every word you look up goes straight into your vocabulary. No extra step. Just keep reading.

Every word you've ever looked up, organized in color-coded folders. Drag, search, revisit. Not a forgotten note — a living vocabulary.

Words captured, active days, peak hours. Small charts that show when you actually read — not when you think you do.

Drop your email. We'll ping you when a beta spot opens.

Built by a reader, for readers. macOS only. Free during beta.
Your vocabulary stays on your Mac — only scanned text touches AI.
