Score: 5.0/10 (Innovation: 4, Technical: 6, Documentation: 7, Utility: 5)

EtherPK adds first-class PDF reading, annotation, form filling, and signing to its markdown note-taking app, with persistent annotations, bookmarks, and agent-assisted Q&A. It addresses a real gap in PKMS tools by keeping PDFs and notes integrated, but it is a feature addition to a proprietary app rather than a standalone open-source project.

Target audience: knowledge workers and note-taking enthusiasts, not developers
