Wordshelf
Learn words while you read
Free · Designed for iPad
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
Look up any word instantly with definitions, pronunciation, and examples
Get a unique AI-generated "memory image" for each word — a visual mnemonic that makes new vocabulary stick
Every word is saved and organized by the book you're reading
Track your reading activity with a visual history of your learning journey
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 MEMORY IMAGES
Each word gets a custom AI-generated illustration designed to help you remember its meaning. These visual mnemonics connect
the word to memorable imagery, making recall effortless.
TRACK YOUR PROGRESS
Watch your vocabulary grow with a visual activity grid (like GitHub's contribution graph, but for reading). See your
streaks, total words learned, and books completed at a glance.
SHARE WITH OTHER READERS
Discover what words other readers are learning from the same books. Share your favorite finds and see what's trending in
the reading community.
Start building your vocabulary today. Every book you read becomes an opportunity to learn.
Ratings & Reviews
Word Rarity Tiers
Every word you look up now shows how rare it is. See exactly how many times per million words it appears in everyday English, color-coded by rarity tier:
- Common (white) — 100+ per million
- Uncommon (green) — 10 to 100 per million
- Rare (blue) — 1 to 10 per million
- Epic (purple) — Less than 1 per million
Tap the frequency card on any word to learn more about how rarity is calculated. Frequency data is powered by Datamuse, drawn from a large corpus of
contemporary English text.
