拍一下就懂。

針對學生最常抱怨的問題而設計

• 講解永遠不上付費牆

  每一次免費拍題都附帶完整的分步講解。付費買的是更多次數，不是解題思路。

• 照片辨識失敗，不會把你踢去別的 App

  認不出照片時，我們給出具體的重拍建議，你也可以直接在原地打字輸入題目。

• 坦誠面對錯誤

  AI 也會出錯。每個答案下面我們都會提醒，講解沒幫上時點一下就能告訴我們。

真正學會所需的一切

• Understand it in one shot

  Photograph or type the question. The AI reads it and explains each step, saying why.

• Ask until it clicks

  Stuck on a step? Ask the tutor. It re-explains in words you can follow, and can draw it.

• Practise until it sticks

  Questions follow your mastery level. Wrong answers are explained on the spot, then similar ones follow.

• Remember it

  Turn any solution into flashcards. Spaced repetition (FSRS) schedules the reviews for you.

• Revise with a plan

  Pick your exam and date for a weekly plan, timed papers, weak-spot diagnosis and score prediction.

• Writing help too

  Sentence-level grammar, tone polish and structure feedback - teaching you to revise, not revising for you.
