Leafy is an AI-powered vocabulary builder and screen lookup tool designed for Mac users. It addresses the common frustration of having to interrupt reading to open standard dictionary apps or browser tabs, which often leads to losing context and focus.
By pressing and holding the key combination ⌥A, users can draw a box around any unfamiliar word on their screen. Leafy works universally across all screen elements, including PDFs, ebooks, images, and web pages. Instead of offering a generic first dictionary definition, Leafy analyzes the exact sentence on screen to deliver a contextual explanation tailored to how the word is being used.
To assist with long-term retention, Leafy automatically saves every looked-up word. It then aids learning by presenting saved words back to the user blanked out within the original sentences where they were first encountered. Leafy includes support for 10 languages.
