Mathful

Mathful is a browser-based math assistant. Users can type a problem, paste or upload an image of a question, or use its calculator, and the service returns a worked solution with intermediate steps. The website lists arithmetic, algebra, geometry, calculus, trigonometry, equations, derivatives, integrals and matrix operations among the supported topics, and it also offers a separate MathGPT page.

The tool is aimed at students checking homework, parents helping with assignments and educators who want to demonstrate methods in class. The provider describes its answers as accurate, but this listing did not test any problems, so solutions should be checked against course material, particularly for multi-step proofs or questions that rely on reading handwriting from a photo.

A free plan gives limited question credits so users can try the solver. The Monthly Pro plan costs USD 9.90 per month and allows 30 questions and 30 image uploads per day, with limits resetting the next day. The Yearly Pro plan is shown as USD 4.90 per month, described as saving 49%, and removes the daily limits for solving and image uploads; the total annual charge was not displayed on the pricing page. Subscriptions renew automatically at the end of each billing period until canceled, and the terms allow the operator to change fees.

The privacy policy says Mathful collects names, email addresses, IP addresses and usage information, including through Google Analytics and cookies, and may send promotional emails. It does not explain how submitted problems or photos are handled by any AI provider or how long they are kept, so avoid uploading images containing personal details.
