Your mistakes
are the syllabus.
Log every wrong question, revise it in an exam-style player until it stops being wrong, hit an AI-set daily practice target, and watch a chapter-wise prep meter fill up.
A body is thrown vertically upward with 20 m/s. Find the time it takes to return to the thrower's hand.
Six moves, on repeat
Set up your target exam
Pick Boards, JEE or NEET during onboarding. Subjects are created for you, and your exam tag is pre-filled everywhere afterwards.
- Choose exam + subjects
- Set your revision frequency
- Add chapters as you study
Everything inside MistakeBuddy
Not another note app. A closed loop between the mistake and the mark.
Snap it, crop it, done
Open the camera right inside the app, crop to the exact question and it is auto-optimised to ~100 KB before saving. Photo or typed — your call.
NTA-style revision screen
Your own wrong questions return in a real exam-style player. MCQ or written — AI checks written answers against the answer you saved.
Spaced repetition that adapts
Right answer pushes it out 1 → 3 → 7 → 16 → 35 days. Wrong answer brings it back tomorrow with higher priority. Three clean hits and it retires.
Adaptive question practice
Log your daily PYQs, modules, NCERT and mocks. After two weeks AI sets a daily target per subject and raises it as you get stronger.
Chapter-wise prep meter
Mark lectures, notes and revision rounds per chapter and get a live completion score — so you always know which chapter is still hollow.
AI weak-area report
Clean bullet-point analysis: which chapters bleed marks, which mistake type costs you most, and what to revise next.
Important points maker
Save what the teacher said — text, images, source, notes — searchable by subject and chapter, forever.
Streaks with meaning
The streak counts revision days, not logins. Mastered questions leave the queue for good.
