Other apps make you do all the work

Typing every translation by hand is slow, and a quick dictionary lookup often hands you five ambiguous options with no context. Generic decks are full of words you'll never use. And cramming the same list over and over doesn't mean it'll still be there next month.

LexAi builds the deck, picks the translation, and runs the schedule

Add a word from a photo, your voice, or a pasted list — AI gives you one clear translation (edit it if you like), then fills in a picture, a definition, and an example sentence. A 5-phase training flow then carries each word from "never seen it" to "know it cold," reviewing it right before you'd naturally forget.

From word to memory, in four steps

Here's exactly what happens after you add a word.

1. Capture

Photograph a sign, menu, or page — or just say the word, type it, or paste a whole list.

2. One clear translation

No list of five ambiguous options. AI gives you a single translation, and you can edit it if you'd word it differently.

3. Auto-enriched

AI fills in a picture, a definition, and an example sentence automatically, before you even open the word again.

4. Trained until it sticks

A 5-phase training flow reviews the word at exactly the right moments to move it into long-term memory.
