A daily plan for your next test.

Built around what students complain about

• Explanations are never paywalled

  Every free scan comes with the full step-by-step explanation. Paying gets you more scans, not the reasoning.

• We don't send you elsewhere when a photo fails

  If we can't read a photo, you get concrete tips and can type the question right there.

• Honest about mistakes

  AI can be wrong. We say so under every answer, and one tap tells us when an explanation didn't help.

Everything you need to actually learn

• 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.
