How it works
You practice speaking
You get a prompt, you speak English, AI analyzes your answer and surfaces new words from context.
Words go on your list
One click and a word is saved — with definition and an example sentence. No manual entry.
Algorithm schedules reviews
A smart algorithm calculates when you'll start forgetting — and shows the word just before that moment. You learn for the long run, not just by drill.
Why an algorithm, not a list?
The Ebbinghaus forgetting curve is clear: without review we forget 70% of new material within a day. A plain word list doesn't help — you need the review at the right moment.
The algorithm calculates an individual review interval for each word. Words you know well show up rarely. Words you struggle with — more often. The result: you learn efficiently, not mechanically.
