A complete tour of 7Solve — from snapping a photo of your doubt to reading a teacher-style explanation. By the end of this you will know not just how to get an answer, but how to use every feature to actually learn from it, which is the whole point.
Most students discover a doubt solver and use maybe a tenth of what it can do. They type a question, read the answer, and move on. That works, but it leaves the best parts untouched — the modes and follow-ups that turn a single answer into a proper little lesson. This guide walks through the tool the way I would sit beside you and show it, so you get the full value out of every question you ask.
What 7Solve is
7Solve is a free AI doubt solver built specifically for Indian students, and that word "specifically" matters. It is not a generic chatbot that happens to answer homework; it is tuned for the syllabuses students here actually study — Class 1 to 10, Intermediate across all streams, degree courses, CA, CMA, US CMA and the major competitive exams.
The other thing that sets it apart is the shape of its answers. Type a question or snap a photo of it — handwritten scrawl or printed textbook, either works — and it responds the way a good teacher would, not the way a search engine does. You get the final answer first, so you are not left in suspense, and then the useful part: the concepts and formulas the question relies on, a clear step-by-step solution, and a note on the mistakes students commonly make on exactly this kind of problem. That last piece is quietly the most valuable, because knowing the trap is often what saves the mark in the exam.
Getting started
The first run takes under a minute, and everything about it is designed to get out of your way.
- Open 7solve.7by.in and sign in with Google or any Gmail address. New accounts get free welcome credits to begin with, and — this is the part that keeps it genuinely usable — every account gets 30 free credits every single day. There is no trial that quietly expires.
- Pick your level and subject. Do not skip this, because it changes everything about the answer. The explanation is tuned to your class, so a Class 7 student asking about ratios and a CA student asking about a ratio-based accounting problem receive very different depth, vocabulary and rigour. Setting your level correctly is the difference between an explanation that fits and one that talks over or under you.
- Type the doubt, or tap the camera and snap the question. You can attach up to five photos at once, which means a whole exercise page — or a multi-part question that spills across two pages — goes in as a single doubt rather than five separate ones.
- Tap Solve my doubt, and the answer appears in seconds, in English, हिंदी or తెలుగు, whichever you have chosen. The trilingual support is not a translation gimmick; the reasoning itself is delivered in your language, which for many students is the difference between following a solution and merely staring at it.
Beyond the answer — the features most people miss
If you only ever tap "Solve my doubt," you are using the tool as a calculator. The features below are what turn it into a tutor, and each one exists to fix a specific bad study habit.
- Hint mode nudges you toward the method without revealing the answer. This is the single most important feature for anyone who cares about actually learning. When you are stuck on homework you genuinely want to attempt, a full solution robs you of the struggle that builds understanding — but a well-placed hint gets you unstuck while leaving the thinking to you. Reach for hint mode first, and full solutions only when you are truly beaten.
- Follow-up buttons let you keep the conversation going without retyping. You can ask for a real-life example when an abstract concept will not stick, request a simpler explanation when the first one went over your head, or generate a practice twin — a fresh problem of the same type — to test whether you have really got it. This is how you close the loop: understand, then immediately prove you understand.
- Tutor mode turns a single doubt into a short interactive lesson, walking you through the idea in stages rather than dumping the whole solution at once. Use it when a doubt is really a symptom of a shaky concept underneath — when you do not just want this answer, but want to stop getting this whole family of questions wrong.
How to actually study with it
Here is the workflow that separates students who improve from students who merely finish faster. When you hit a doubt, do not open 7Solve immediately. First attempt the problem yourself and, if you stall, use hint mode. Only after a real attempt should you read the full solution — and when you do, read the steps, not just the final number. Then, crucially, tap the follow-up to generate a practice twin and solve that one on your own, unaided. If you can, the concept is yours. If you cannot, you have found a gap worth filling now rather than in the exam hall. Attempt, hint, solution, twin: that four-beat rhythm, repeated, is worth more than any amount of passive answer-reading.
Fair usage and the Pro plan
The credit system is deliberately simple and generous. Each answer costs 10 credits, so your 30 free daily credits give you three fully explained answers a day, every day, at no cost — enough for a typical student's real doubts without ever paying a rupee. The credits refresh daily, so there is nothing to hoard.
The Pro plan exists for a specific reason rather than as a paywall on basic use. Genuinely hard questions — CA and CMA numericals, dense multi-part problems, anything that needs deep reasoning — are routed to the most powerful and expensive AI models, and those are reserved for Pro. It costs ₹47 a month or ₹499 a year, payable by UPI or card. For most school and intermediate students the free tier is plenty; for serious professional-exam candidates leaning on it daily, Pro pays for itself in the first difficult problem it cracks. Either way, you always know what you are getting before you spend a credit.
