MathSolver is a free online AI math-solving tool, officially positioned as a "free AI math solver," that can provide instant step-by-step solutions.
In terms of use, it is aimed at learning and homework scenarios and claims to cover major math topics such as arithmetic, pre-algebra, Algebra I and II, geometry, trigonometry, precalculus, calculus (including AP AB/BC and above), differential equations, linear algebra, and probability and statistics, and it also handles common cross-disciplinary STEM problems in physics and chemistry.
Its main capabilities include: step-by-step solutions, where each calculation is presented as a separate numbered step and explains in plain language the formulas used and why; photo solving, allowing you to take or upload handwritten or printed problems, with image recognition reading the equations and solving them; practice quizzes, which can generate customized quizzes for any topic and difficulty; a graphing calculator, which can plot functions in the browser, find intersection points, and overlay multiple functions for comparative analysis; after solving, you can ask follow-up questions in chat, and the system will remember the context and continue explaining. The official description also mentions that images or PDFs can be uploaded.
How to use it: enter an equation, describe a word problem in your own words, or upload a photo; the AI analyzes it and returns a step-by-step solution; if you are not satisfied, you can continue asking follow-up questions. The official three-step process is listed as: enter the problem, get a step-by-step solution, and ask follow-up questions. On mobile, iPhone and Android apps are available, allowing you to scan problems, check handwritten homework, practice, and save video courses for offline viewing; the browser version can also be used directly on phones and tablets without installation.
Applicable scenarios: mainly for students' self-study, homework checking, and pre-exam practice, and it can also be used by teachers or self-learners as a reference for solution methods.
Languages and cost: the interface offers 16 languages, switched via the sidebar or the globe icon at the top on mobile, and each language has its own shareable page URL; the solving interface, new step-by-step solutions, and practice questions use the language of that page, while calculator guides, articles, account pages, and video courses are currently in English. The official description says it is completely free, with unlimited problem solving, access to all step-by-step explanations, and generation of practice quizzes, with no account and no subscription required.
Limitations and notes: the official notice reminds users that although AI solving has been trained on a large number of math problems and has relatively high accuracy, for exams or professional use it is still recommended to review key calculations yourself. Regarding whether teachers can detect the use of an AI math solver, the official explanation states that numbers and steps themselves are mathematics and cannot be detected, but written explanations may be flagged by AI detectors, so it is recommended to write in your own words. The materials do not provide specific pricing, subscription plans, or any fee information other than free.
