7Solve — AI Doubt Solver

7Solve is a doubt solver for students, from school to degree. Snap a photo of a question or type it, and 7Solve gives you the answer with a clear step-by-step explanation.

What makes 7Solve different: it checks the maths. Every calculation in an answer is recomputed on your phone, and the answer page tells you plainly what was checked, what agreed, and anything it could not confirm.

• Photo or type — printed or handwritten questions
• Five explanation levels, from Quick to Expert
• Learning Toolbox on every answer: Understand · Practice · Study · Exam — explain like I'm 10, why the method works, a harder version, a quiz, flashcards, a mind map, a revision sheet
• Mind Games: quick-fire quizzes with clear A/B/C/D options and honest, checked answers
• Current affairs answered as what happened, key facts, background and possible exam questions
• Mistake Book: the questions you got wrong, your correct and wrong count per topic, and what to practise next
• Notebook for saved doubts, flashcards and revision sheets
• Class 1–10, Intermediate (MPC, BiPC, CEC, MEC), Degree, CA, CMA, US CMA, jobs and current affairs

One 7By account signs you in to 7Solve and every 7By app. Manage or delete your account any time from Settings.

7Solve uses AI to write explanations, and AI can make mistakes. The on-device checks catch arithmetic errors, but always read the working — and tap "Report it" on any answer that looks wrong.
