MathGPT (mathgpt.app) is a free, browser-based AI math solver that accepts a problem typed as text or LaTeX, built with an on-screen formula keyboard, or uploaded as a photo, and returns a line-by-line worked solution that finishes with a check.
What is MathGPT?
MathGPT is a free AI math solver that runs in the browser at mathgpt.app. It takes problems as typed text, LaTeX, or a JPEG, PNG, or WebP photograph, and produces each line of working on its own line with a sentence describing the operation, then substitutes the answer back into the original problem to verify it. Coverage runs from arithmetic, fractions and percents through algebra, geometry, trigonometry, coordinate geometry, sequences, probability, statistics, and calculus including limits, derivatives, integrals and series. There is no account, no credit counter, and nothing to install.
What makes MathGPT stand out?
- Line-by-line working — every solution shows the method step by step rather than only a final number, and ends with a substitution or estimate that checks the result.
- Photo transcription you approve first — an uploaded photo comes back as editable math, so a misread exponent gets fixed before anything is solved instead of producing a confident answer to the wrong question.
- Formula keyboard — fractions stack, roots get a radical, and exponents sit in the corner, so expressions like a nested fraction are unambiguous; plain text entry remains available.
- Check-my-work mode — paste your own working and MathGPT names the first line that goes wrong and what the error was (sign, distribution, a dropped solution), then continues correctly from there.
- Practice generator — after solving something, ask for five more of the same kind; one comes worked through and the rest come with answers for self-marking.
- 326 formula and theorem references — each formula page has the statement typeset, one line per symbol, three worked examples, common mistakes, and a solver scoped to that formula.
- Six dedicated solvers — Algebra, Calculus, Word Problem, Photo Math, Check My Work, and Practice Problems each have their own page.
- No account barrier — no sign-up, no card, no expiring trial, and no credit counter, including for the photo solver.
Who should use MathGPT?
- High school and college students working through algebra, geometry, trigonometry, statistics, or calculus problem sets who need the intermediate steps, not just the answer key's final number.
- Students with paper homework who would rather photograph an integral with three levels of nesting than retype it, and want to confirm the transcription before solving.
- Learners who got the wrong answer and need to find the exact line where their method broke, using check-my-work mode to diagnose the error rather than re-solving from scratch.
- Anyone revising a topic who wants five more problems of the same type, with answers, after something has clicked.
Use cases
- Homework diagnosis: paste your working into check-my-work, read the flagged line, and see what the correct manipulation from that point looks like.
- Photo problem entry: upload or paste a picture of a printed or handwritten question, correct the returned transcription, and get a full solution with a verification step.
- Self-testing: generate five practice problems of the same kind after a solved example, work them unaided, and mark against the provided answers.
- Exam reference: look up any of 326 formulas with symbol-by-symbol explanations and the mistakes people commonly make with them.
How does MathGPT work?
- Enter the problem: type it as text or LaTeX, build it with the formula keyboard, or upload, drag in, or paste a photo.
- If you used a photo, review and edit the transcription MathGPT returns before anything is solved.
- Press solve: MathGPT shows each line of working with an explanation, then substitutes the answer back to check it.
- Optionally switch to check-my-work with your own attempt, or ask for five more problems of the same kind.
Pricing
MathGPT is free. There is no account, no card, no expiring trial, and no credit counter. The stated limit is a shared daily AI allowance; when it runs out you are told so plainly rather than shown an upgrade button.
Alternatives
ChatGPT (a general chat assistant rather than a math-specific solver), Photomath (phone-first photo scanning), and Wolfram Alpha (a computational knowledge engine).
FAQ
Is MathGPT really free?
Yes. MathGPT has no account, no card, no expiring trial and no credit counter. The one stated limit is a shared daily AI allowance — if it runs out, the site tells you so rather than showing an upgrade prompt.
Do I need to sign up for MathGPT?
No, and that includes the photo solver, which the site notes most competitors put behind a login. You open the page, type or upload the problem, and press the button.
Does MathGPT show steps or just the answer?
Steps, always. Each line of algebra sits on its own line with a sentence explaining what was done, and the solution finishes by substituting the answer back into the original problem.
Can MathGPT read handwriting?
Usually, if the photo is in focus and the page is flat. MathGPT returns the transcription as editable math before solving, so a misread character can be fixed instead of yielding a confident answer to a problem you never asked.
Can I trust a MathGPT answer?
The site states that MathGPT is a language model, not a computer algebra system, so arithmetic slips can occur in long chains of manipulation — which is why every solution ends with a check, and why heavy numeric work warrants a second verification.
