About

Solvr

Features
Read full description

Solvr is your verified academic reasoning workspace for technical subjects. Built for students who want to understand exactly where they stand, not just get an answer. WHY SOLVR IS DIFFERENT Most AI tools will hand you an answer. Solvr shows its work and checks it. Every numerical solution is independently verified using a real symbolic computation engine (SymPy), running in a sandboxed environment, so you get correct, trustworthy answers instead of confident-sounding guesses. If an answer doesn't check out, Solvr automatically tries again with deeper reasoning before showing it to you. MISTAKE DETECTIVE — SEE EXACTLY WHERE YOU WENT WRONG Snap a photo of your own work next to the problem, and Solvr solves it independently, then compares your steps against the correct solution step by step. If you made an error, Solvr pinpoints the exact line where your reasoning diverged and explains the underlying misconception, so you actually learn from it. And if your work is correct? Solvr tells you that too. No invented errors, no false alarms. HOW IT WORKS • Snap a photo of any problem (handwritten, printed, or a full worksheet) or upload a PDF directly • Get a clean, step-by-step solution with properly typeset math; every problem on a worksheet is solved in one pass, not one at a time • Ask Solvr follow-up questions about any step, right in the chat • Use Mistake Detective to check your own attempt against the correct solution • Track your Weakness Graph (the concepts that trip you up most) and get targeted practice problems to fix them • Export any solution as a clean PDF or Markdown study sheet BUILT FOR STEM Solvr handles everything from basic algebra to multi-step calculus, physics mechanics, and chemistry stoichiometry with full LaTeX-rendered equations. PLANS • Free: 3 verified solves a day, math only, perfect for trying it out • Solvr Pro: unlimited solves across all STEM subjects, Mistake Detective, Weakness Graph, follow-up chat, and clean exports Solvr is a study tool designed to build understanding, not shortcut it. Every feature is built around one question: does this help you actually get better? Terms of Service: https://getsolvr.app/terms Privacy Policy: https://getsolvr.app/privacy
