Mathful

Mathful is an AI-powered math solver that lets users type a problem, upload a photo of it, or use a built-in calculator to get a full step-by-step solution. The tool covers a broad range of topics, including elementary arithmetic, word problems, geometry, algebra, calculus, trigonometry, and statistics, and is available in the browser at any time. Mathful states its solutions reach 98% accuracy and positions itself as an alternative to general-purpose chatbots like ChatGPT for math specifically, aiming to show the full working behind an answer rather than just the final result. The tool is free to try, with paid subscriptions available for users who need to ask more questions than the free tier allows. It targets students from elementary school through university, as well as anyone studying for exams or checking their own work. Mathful does not publish details about a mobile app, API, or third-party integrations, and its site does not state a founding year or company name behind the product. One limitation is that, like other AI solvers, its accuracy on multi-step or unusually worded problems is not independently verified beyond the company's own claim.
