Lexicon
A vocabulary app for people learning a language.
Collect the words you run into, review them in short sessions, and pick up where you left off on Android, iOS, or the web. Got a long text? Let AI pull the words out for you.
Why Lexicon?
New words end up everywhere: a notes app, a flashcard app, a screenshot you never look at again. Lexicon keeps them in one list and makes sure you actually see them again.
- Your words on every deviceUse it on Android, iPhone, or the web. Sign in and your word list follows you.
- Import with AIPaste a text, upload a file, or drop in a screenshot. AI picks out the words worth learning so you don't have to type them.
- Review at the right timeWords come back for review just before you'd forget them. The ones you know well show up less often.
Bring your words to Claude, ChatGPT, and other AI apps
Connect an AI app to your Lexicon account. Ask which words are due and get quizzed in the chat, add new words from an article you're reading, or talk through your weekly progress. You choose what it can see, and you can disconnect it any time.
