Capcat – CLI/TUI to Archive Articles as Markdown and HTML (FOSS)

Capcat is a free, open-source Python CLI/TUI tool that ethically archives web articles and RSS feeds into clean Markdown and HTML files. It is designed for researchers, journalists, and digital preservationists who need a reliable, offline-friendly way to save online content without scraping or violating site ethics. Its interest lies in combining NLP, context-engineering, and LLM-driven development to produce a fully functional, spec-compliant archiver that prioritizes both utility and responsible use.
