Recall - 英语词汇训练

You know the word "ubiquitous." You understand it when you read it. But when was the last time you actually used it in a sentence?

That gap between words you recognize and words you produce is real. Recall was built to close it.

WHY RECOGNITION IS NOT ENOUGH

Most vocabulary apps test whether you recognize a word — flip a card, pick the right answer, move on. But research shows recognition and production are different skills. You can "know" thousands of words and still freeze when trying to use them in speech or writing.

Recall replaces passive flashcard flipping with active production. You explain meanings in your own words. You create sentences. An AI evaluator scores your response and helps you improve.

HOW IT WORKS

1. A word appears from your vocabulary
2. Explain the meaning or use it in a sentence
3. AI evaluates your response on a 0-5 scale
4. Smart spaced repetition brings it back at the right time

Score a 5? You won't see it for weeks. Score a 2? It comes back tomorrow. The algorithm adapts to your actual production ability, not your self-assessment.

PRACTICE MODES

Explain Meaning — Describe what a word means in your own words. AI checks whether you captured the core concept and suggests improvements.

Use in Sentence — Create a natural sentence using the word in context. AI evaluates grammar, word usage, and naturalness.
