How it works
- One pair a day. Two easily confused English words (like Begin vs Start), each with a black-and-white illustration.
- Explain the difference. Write, in English, how the two words differ in meaning, tone, and usage.
- Get AI feedback. An AI scores your answer across five dimensions — accuracy, coverage, language, clarity, insight — then reveals the model answer.
- Build a streak & share. Keep a daily streak and share a no-spoiler result card, Wordle-style.
DailyDiff is a focused way to master English synonyms and near-synonyms — one subtle difference at a time.
怎么玩
- 每天一对。一组容易混淆的近义词（如 Begin vs Start），各配一张黑白线稿插图。
