The 5 best doubt solving websites, ranked
- #1
Doubtclip
Our pickDoubtclip (India)Doubtclip is an AI doubt solver built around video. Upload a photo or screenshot (or paste the text) and it solves that exact question, draws the working on a whiteboard — on the question’s own figure when there is one — and narrates it in English or Hinglish. You also get the written step-by-step solution and PDF notes for revision.
Best for: A fresh whiteboard video for your exact Physics, Chemistry or Maths question — JEE, NEET, boards, AP, IB, GCSE
Strengths
- Video is made for your question, not a “similar question” from a library
- Explains on the original diagram — forces, angles, circuits and graphs are marked on your figure
- Hinglish narration for Indian students, English for everyone else
- Written steps + PDF, and an answer self-check for numerical questions
- Free step-by-step calculators for common Physics, Chemistry and Maths formulas
Keep in mind
- Focused on STEM (Physics, Chemistry, Maths) — not essays or humanities
- A video takes a little longer than an instant text answer
- Free trial, then paid plans — see the pricing page
- #2
Doubtnut
Doubtnut (acquired by ALLEN Career Institute in 2023)Doubtnut is one of the best-known Indian doubt apps. You photograph a question and it looks for a matching solution video from a very large library built around NCERT, board, JEE and NEET material, with Hindi and English videos.
Best for: Indian students who want a large library of short video solutions for NCERT, JEE and NEET questions
Strengths
- Huge library of NCERT, board, JEE and NEET questions
- Hindi-medium friendly
- Fast when your question is already in the library
Keep in mind
- If your exact question is not in the library you get the closest match, which may differ
- Videos are pre-recorded, so they do not follow your specific figure or numbers
- #3
Photomath
Photomath (owned by Google)Photomath is a camera maths solver. Point it at an equation or expression and it shows the steps to solve it. It is excellent for pure maths practice, but it is maths-only, so it is not built for Physics or Chemistry doubts or for word problems with diagrams.
Best for: Step-by-step maths: arithmetic, algebra, trigonometry and calculus from a camera photo
Strengths
- Very quick for equations and expressions
- Clear step-by-step maths working
- Good for checking homework answers
Keep in mind
- Maths only — no Physics or Chemistry
- Diagram-based and long word problems are not its focus
- #4
QANDA
Mathpresso (South Korea)QANDA by Mathpresso lets you photograph a question and find solved answers from its large database, with AI study help on top. It is widely used in Korea, Vietnam, Indonesia and other Asian markets.
Best for: Photo search for solved questions plus AI help, popular across Asia
Strengths
- Large solved-question database
- AI study helper
- Strong in maths
Keep in mind
- Answers are often from similar questions in the database
- Less focused on Indian JEE/NEET-style Physics and Chemistry
- #5
Chegg
Chegg Inc. (United States)Chegg is a long-running US homework-help subscription with step-by-step textbook solutions, expert Q&A and AI answers across many college subjects. It suits university coursework more than school-level JEE/NEET doubts.
Best for: US college students who want textbook solutions and expert Q&A across many subjects
Strengths
- Covers many college subjects
- Textbook-linked solutions
- Expert Q&A
Keep in mind

Why we rank Doubtclip first
A video for your question — not a similar one
Most doubt apps answer by finding a question that looks like yours. That works when your question is common, but breaks when the numbers, the diagram or the twist are different. Doubtclip solves the question you actually uploaded and explains it on its own figure, so what you watch matches what you have to write in the exam.
Frequently asked questions
Which is the best doubt solving website?+
It depends on what you need. For a whiteboard video made for your exact Physics, Chemistry or Maths question — on its own diagram, in English or Hinglish — Doubtclip is our pick. For a large library of pre-recorded NCERT/JEE/NEET videos, Doubtnut is popular. For pure maths steps, Photomath is quick. For US college coursework, Chegg covers many subjects.
What is the best doubt solving app for JEE and NEET?+
For JEE and NEET Physics, Chemistry and Maths doubts, Doubtclip generates a step-by-step whiteboard video for your exact question with Hinglish narration, plus written steps and a PDF. Doubtnut is another common choice when your question is already in its library.
Is there a Doubtnut alternative that makes a video for my exact question?+
Yes. Doubtclip creates a new narrated whiteboard video for the question you upload instead of matching it to a pre-recorded video, so the numbers and the diagram in the video are the ones in your question.
Is there a Photomath alternative for Physics and Chemistry?+
Photomath focuses on maths. Doubtclip covers Physics, Chemistry and Maths, including diagram-based questions such as circuits, free-body diagrams, ray optics and organic structures.
Can I ask doubts in Hindi or Hinglish?+
Doubtclip can narrate the video solution in Hinglish (Hindi + English, the way most Indian teachers explain) or in English. Doubtnut also has Hindi-medium videos.
Is Doubtclip free?+
New accounts get a free trial, and paid plans are available for more videos — see the pricing page. The step-by-step calculators on Doubtclip are free.
