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.
Start building your vocabulary today. Every book you read becomes an opportunity to learn.
Amazing for reading: you can take a picture of the page you are reading and it will tell you the word’s meaning in that specific context. With etymology and frequency of use and time period where it was used the most - which is very useful if you are still learning the language. Super recommended!
Almost the perfect app
Nicknicckicks
It has the best layout, not overwhelming or over complicated like other apps, does not shove Ai, adds, or payment plans in your face every time you use it. The app has feedback section in it, which is responded to in a timely manner, with friendly conversation and discussion on improvements. They will even add new words upon request. This app does use AI, or is “Ai-powered” whatever that may mean and I’m not the biggest fame, but I’m not in control of the evolution of Ai old it’s integration into everyday things. Overall with time and feedback from people who use it regularly it will continue to improve if they continue this acceptance of feedback.
Perfect App to Pair with my Books
TheMusicanGamer
I downloaded many dictionary apps this is the exact app I was looking for. It categorizes words based on books. It provides definitions, word usages, trends, and examples. It’s amazing, intuitive, and no nonsense. As a developer, I’ll also support solo developers. Great work and looking forward to future updates.
App of the Year
Komrade97
By far one of the coolest apps I’ve ever gotten on my phone. I may be overshooting, but do you guys plan on “gamifying” Wordshelf via adding achievements and the ability to add friends and see their profile? I would love to have such features added.
Thank you for the awesome feedback! Readers asked for a better calendar, so now you can tap a word in any day to see its meaning, and swipe from day to day. Be sure to check it out.
Also new: an experiment with spatial memory flashcards. Walk into a 3D library and put your words at spots around the room. We don't know yet if they work better than normal flashcards, but they are a lot of fun. Find them in the Learn tab.
