LeafyApp
macOS app that looks up any on-screen word with a hotkey, generates a sentence-aware definition, and saves the word with its sentence for spaced-repetition review
Launch screenshots from Product Hunt, Aug 2026
The product is a macOS application that looks up any word on screen with a hotkey, using OCR and AI to provide a definition based on the surrounding sentence and automatically saving the word with its sentence to a local library for later review with spaced repetition. It is for individual consumers and general readers who encounter unknown words while reading across PDFs, ebooks, web pages, images, and video subtitles. Compared to copying to tabs and dictionary workflows, it is positioned as a one-keystroke capture that keeps the user on the page without switching context.
