Snap your doubt, get it solved step by step
A good doubt solution doesn't just show the final answer. Learnsable's Ask a Doubt breaks the question down, explains the concept behind it, walks through the solution, and gives you a similar problem to try — so you can solve the next one yourself.

What it does
- Type the question, take a photo with your camera, upload a photo or PDF, paste a screenshot, or dictate it
- Understanding the question — it restates what's being asked
- The concept — the idea you need, in plain language
- Step-by-step solution — each step with the reason it follows
- Practise the same idea — a fresh problem to try
How it works
Add your doubt
Snap a photo of the question or paste it in. Mention the subject or class if it isn't obvious.
Read the breakdown
Go through the question, the concept and the worked steps in order.
Try the practice problem
Solve the follow-up on your own, then check it — that's where the learning happens.
Try asking
- “A block of mass 2 kg slides down a 30° incline with friction μ = 0.2 — find the acceleration.”
- “Why does my integral by parts keep going in circles? [attach photo]”
- “What does this sentence mean in the passage? [paste the paragraph]”
Good to know
- A solved doubt uses 2 credits.
- Handwriting and diagrams in photos can be misread. If the answer looks off, retype the question and ask again.
- For calculations, check the final number yourself — AI can slip on arithmetic even when the method is right.
Frequently asked questions
Can it solve questions from a photo?
Yes. Use the camera or upload a photo or PDF. Clear, well-lit photos of printed or neatly written questions work best.
Is this just giving me the answer to copy?
It's designed to teach: it explains the concept and each step, and gives you a similar problem to practise. How you use it is up to you and your institution's rules.
Which subjects does it cover?
Any subject you can describe in text or a photo. Maths, physics, chemistry, biology, accounts and programming doubts are typical examples.
