Score: 6.0/10 (Innovation: 5, Technical: 6, Documentation: 7, Utility: 6)

Papa is an open-source CLI and Python library that provides Hemingway-style readability linting for Markdown and text, flagging hard sentences, passive voice, and complex phrasing. It generates JSON and HTML reports, integrates into CI pipelines, and respects Markdown structure by ignoring code blocks and frontmatter. Its focus on being scriptable and automation-friendly fills a gap for teams wanting to enforce prose quality in documentation workflows.

Target audience: technical writers, documentation engineers, backend devs, devops
