Lexxi is a personal vocabulary companion. Type in any word or phrase you come across while reading, and Lexxi defines it instantly using AI — correcting misspellings, detecting whole phrases and idioms (not just single words), and saving everything to your personal library so you never lose a word you’ve looked up again.

A dictionary gives you a definition and lets you forget it five minutes later. Lexxi is built around retention, every word you look up is automatically saved to your library with an example sentence, so you can revisit it later. You also get spaces like Brain Dumps and Quotes to actually practise and use what you’ve learned, which is the step most dictionary apps skip entirely.

Both. If you type a single word, Lexxi corrects spelling if needed and gives you its definition. If you type a multi-word expression, like “bite the bullet” or “drawing a complete blank”, Lexxi recognizes it as a phrase and explains what the whole expression means, rather than defining each word separately.

Yes. The Free plan gives you 100 entries total across words, phrases, quotes, and brain dumps combined, enough to properly try the app and build a real starter library, with no card required to sign up.

Pro removes the 100-entry limit entirely, giving you unlimited words, quotes, and brain dumps, plus features like CSV export and priority access to new tools as they launch. It’s KSh 500/month, paid securely via M-Pesa or card.

Yes, and no app store needed. Lexxi is a Progressive Web App, visit app.lexxi.xyz on your phone’s browser, tap “Add to Home Screen,” and it installs like a native app, complete with its own icon and full-screen experience.

Looking up a new word requires an internet connection, since definitions are generated live by AI in the moment. Words you’ve already saved to your library remain viewable once the app has loaded them.

Brain Dumps are a distraction-free writing space, think of it as a place to think out loud and practise using your newly learned vocabulary in your own sentences, which is what actually makes new words stick. Quotes let you save memorable lines you come across in your reading, complete with the author, so you build a personal collection of writing you admire alongside your vocabulary

Yes, your library is completely private. Every word, quote, and brain dump you save is tied only to your account, no other user can ever see your personal library, and your data is protected at the database level, not just hidden in the interface.
