ProofCheck is a website and tool that helps users write and check complete mathematical proofs in TeX. Its core concept is straightforward: the checker matches each step of the proof against a long list of inference rules one by one. If a step matches a rule, it passes; once all steps pass, the entire proof passes. Based on the syntactic ideas of A.P. Morse, its goal is to achieve complete formalization while adding as little formalism as possible and deviating as little as possible from accepted mathematical notation.
Based on the fetched text, ProofCheck is designed for the TeX/LaTeX mathematical writing workflow, with the checker implemented via Python scripts. The page provides a short arithmetic proof example in Plain TeX and a short set theory proof example in LaTeX, as well as an online syntax checker and documentation entry. Its advantage lies in not requiring users to completely migrate to a dedicated proof assistant language; instead, it attempts to perform proof checking close to traditional TeX notation, making it suitable for those already writing mathematical content in TeX.
The page describes ProofCheck as an "open system" aimed at maximizing user control; however, the main text does not explicitly provide an open-source license, source code repository, or community governance information, so it cannot be directly determined whether it is open-source software. It offers downloads for Linux/Unix/OS-X and Windows, indicating it can be run locally; however, there is no mention of self-hosting services, APIs, SDKs, editor plugins, CI integration, or a package management ecosystem.
The fetched content contains no information about fees, subscriptions, or commercial licenses, nor any payment methods. Support is primarily available by emailing Bob Neveln, with a requirement to include "ProofCheck" in the email subject. Additionally, the page references a paper from The PracTeX Journal and a 2012 Python conference poster, indicating some academic background material, but the main text shows no signs of active maintenance, and the download section still prompts "A New Version is Coming Soon".
Pros include a clear concept, close alignment with traditional mathematical notation, TeX/LaTeX support, and the availability of an online syntax checker and examples. Cons include insufficient information disclosure, lacking details on licenses, versions, installation, ecosystem integration, and APIs; meanwhile, the barrier to entry may be higher than standard document tools. It is more suitable for users in mathematics, logic, or formal proof teaching/research who wish to perform proof checking within their TeX documents. Accessibility, network stability, and payment options for users in China cannot be determined from the main text; if a more mature ecosystem is needed, alternatives like Coq, Lean, Isabelle/HOL, Agda, or Mizar can be compared.
