Learn smarter while you read.
Wordshelf makes it effortless to capture, understand, and remember every new word you come across — whether you're reading a book, studying, or exploring ideas.
HOW IT WORKS
Scan any page with your camera to instantly identify and look up words, or type them in. Get definitions, pronunciation, examples, synonyms, and etymology. Each word gets a personalized mnemonic and AI-generated memory image to make it stick. Every word is saved and organized by the book you're reading.
BUILT FOR READERS
Unlike generic dictionary apps, Wordshelf is designed around how you actually read. Set your current book, and every word you look up is automatically linked to it. When you finish, you'll have a beautiful collection of everything you learned.
REMEMBER MORE WITH AI
Each word gets a custom mnemonic using the keyword method — linking the word's sound to a vivid mental image. Plus an AI-generated illustration to reinforce it. No more forgetting words you've looked up before.
TRACK YOUR PROGRESS
Watch your vocabulary grow with a visual activity grid. See your streaks, total words learned, word difficulty stats, and books completed at a glance.
20+ LANGUAGES
Supports English, Spanish, French, German, Japanese, Korean, Chinese, Arabic, Hindi, Portuguese, and more.
