每天一道近义词辨析。
用英语写出区别，AI 五维点评，连续打卡。

即将登陆 App Store。

How it works

  1. One pair a day. Two easily confused English words (like Begin vs Start), each with a black-and-white illustration.
  2. Explain the difference. Write, in English, how the two words differ in meaning, tone, and usage.
  3. Get AI feedback. An AI scores your answer across five dimensions — accuracy, coverage, language, clarity, insight — then reveals the model answer.
  4. 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

  1. 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。
  2. 写出区别。用英语描述两个词在含义、语气、用法上的不同。
  3. AI 点评。AI 从准确性、覆盖度、语言、清晰度、洞察五个维度评分，并揭晓标准答案。
  4. 打卡 & 分享。维持每日连续记录，像 Wordle 那样分享一张不剧透的成绩卡。

DailyDiff 用最聚焦的方式帮你攻克英语近义词辨析 —— 每天搞懂一个细微差别。
