GoMim Math Solver vs Xcas

GoMim Math Solver analyzes typed math questions and uploaded photos, then provides step-by-step solutions. Images can show handwritten or printed problems. Its listed topics include basic math, algebra, geometry, calculus, and statistics. The service is aimed at students as a study and homework aid, and also mentions parents and educators. It is available on Android, iOS, and the web; GoMim says results can sync between mobile and desktop, and its guide describes browser use without downloading an app. The free plan costs nothing and includes 10 credits per day, image and text input, question history, 24/7 AI tutor support, and no ads. PRO costs $4.99 a month for 5,000 monthly credits without a daily limit; Unlimited costs $7.49 a month with unlimited monthly credits. Each question or solution typically uses two credits, though complex or multi-step problems may use more. Credits do not roll over, and balances and usage limits reset at the start of each billing cycle. Submitted text and images are processed to generate solutions and may be handled by third-party AI providers.

Xcas is a free interface for computer algebra, geometry, graphs, spreadsheets, statistics, and programming. Its symbolic tools include arbitrary-precision arithmetic, polynomial operations, simplification, equation solving, calculus, and linear algebra. Users can build programmable dynamic 2-D geometry and work with 3-D geometry and graphs. The spreadsheet supports relative and absolute references, formal objects in cells, and one- and two-dimensional statistics, including regressions. Programming features include functions, variables, tests, loops, an editor, a debugger, and C-like, Maple, MuPAD, and TI89 syntax modes. Xcas runs on Android, iOS, Linux, macOS, web, and Windows. The browser version can work locally without installation or an internet connection, though it is less complete and slower than compiled desktop versions. The Giac library can be used from C++, Python, Java, and JavaScript programs; the site also describes LaTeX and TeXmacs interfaces. Xcas is free under GPL3, but commercial software inclusion requires contacting the makers about a dual license. The site offers tutorials, guides, a forum, and documentation, which it calls incomplete on its English overview.
