How to Scan a Question (Camera Feature)
The scan question feature is what most students use daily. These tips give better matches:
Tap the camera icon
On the home screen — orange camera button in the center or bottom bar.
Frame one question
Include only one problem per photo. Avoid shadows and blur.
Capture & wait
AI processes in 5–10 seconds. Crop if the app asks.
Pick the best match
If multiple results show, choose the question that looks identical to yours.
Watching Video Solutions
After a successful scan, doubtnut video solutions play automatically. You can pause, rewind 10 seconds, change playback speed, and save videos for offline viewing (where supported). Watch the full explanation — do not skip to the final answer only. Note the method in your notebook and solve a similar problem yourself to confirm understanding.
For competitive exams, combine with IIT JEE or NEET study plans.
Browsing NCERT Without Scanning
Not every session needs the camera. Go to Study or NCERT section → select class → subject → chapter → exercise → question number. This is ideal when you know exactly which NCERT problem you need — faster than scanning for Class 10 or 12 homework.
Live Classes & Premium Features
Free users get limited live classes; premium unlocks full schedules for JEE, NEET, and boards. Check the Live tab for today's sessions. PDF notes and test series are under premium — see free vs premium on the homepage.
