MathPad vs PARI/GP

MathPad is an AI math workspace for solving, explaining, and teaching math. Its SnapSolve tool reads handwritten or printed math from a photo, then returns a step-by-step solution with CAS verification. The AI Tutor offers interactive conversations, hints, guidance, concept explanations, and work verification. A math editor supports LaTeX, AsciiMath, MathML, Typst, and MathJSON with live preview; OCR can extract equations and text together. Document conversion supports more than 21 formats, including PDF, DOCX, LaTeX, EPUB, and Jupyter notebooks. Add-ons work in Google Docs, Sheets, Slides, and Forms, while the Office add-in supports Word, Excel, and PowerPoint on desktop and Office Online. MathPad also offers public APIs for LaTeX-to-image rendering and math-format conversion. It runs on Android, iOS, Linux, macOS, web, and Windows, plus an extension. The free plan has 10 daily credits and three AI Tutor trial messages per day; paid plans start at $14.99/mo.

PARI/GP is a free, open-source computer algebra system designed for fast number-theory computations. Its functions cover factorization, algebraic number theory, elliptic curves, modular forms, L-functions, matrices, polynomials, power series, algebraic numbers, and transcendental functions. PARI is available as a C library; gp is an interactive shell, and GP is its scripting language. The gp2c compiler translates a subset of GP scripts to C and can make compiled scripts three or four times faster. The official site offers a browser-based GP interface for expressions, variables, and function definitions, though its stated speed is approximately 15% of native speed. Xeus-GP is a Xeus-based Jupyter kernel. Optional packages are distributed separately because they use substantial disk space and are expected to be unnecessary for most users. The project provides guides, reference manuals, tutorials, quick reference cards, and downloadable manuals. The project directs users to a mailing list for help and a bug tracker for reports and feature requests. It is licensed under GNU GPL version 2 or later.
