Everything around the feed

The Discover feed is the front door. These are the rooms behind it.

An AI tutor for every word

Any word opens a chat. Ask for the definition, example sentences, synonyms, etymology, or the grammar behind it — or write your own sentence and get it corrected. It answers at your level, not a textbook’s.

A dictionary that takes wildcards

Every word is CEFR-graded from A1 to C2, with sentences, idioms, and lexical chunks. Pattern search finds “four-letter words ending in -de” when the exact word is on the tip of your tongue.

Reminders at your level

Get a few new words a day, matched to your CEFR level. Saved a hard word? Set a reminder on it and it comes back until it sticks.

A word history that works for you

Every word you save is taggable, searchable, and playable. Filter games to your saved words, or to one tag — “kitchen verbs” is a legitimate study plan.

Hear it, at your speed

Text-to-speech in multiple accents, with adjustable speed. Slow it down for new sounds, speed it up before a trip.

Learners, not just an app

Follow other learners, message them, and share posts. Someone else is learning your language right now.
