CameraMath vs Xcas

CameraMath solves math problems from photos, screenshots, handwritten questions or typed text and gives step-by-step explanations. Its online solver covers pre-algebra, algebra, pre-calculus, inequalities, calculus, trigonometry, geometry, statistics, probability and matrices. The free online plan is listed at free and supports photo, screenshot, handwriting, text and calculator inputs. Most site features are available without registering for an account. The service is available on web, Android and iOS; for mobile use, the site directs users to the UpStudy app, which also offers additional study resources. The UpStudy API can return single answers, brief answers or detailed step-by-step solutions, and its documentation describes a limited-time free trial without stating its duration. CameraMath presents the solver for students and professionals doing homework, checking answers or preparing for exams. Its headquarters are in Singapore, and support is available by email. The privacy policy says it may collect entered questions, uploaded images, profile details, usage behavior, crash logs, device information and IP addresses.

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.
