shelff – PDF Book Reader

Organize owned PDF books using folders, metadata files and an annotation-capable reader.

Our take

Useful for people wanting file-based library portability

JSON metadata beside PDFs and incremental annotations expose where data lives.

Keep in mind: DRM-free PDFs only as described; encrypted-file support is not password removal and full-text search needs text/OCR layers. Test backups before external agent changes.

What you can do

  • Folder/tag/collection/status library
  • Page layouts/crops, highlights/comments and search
  • Editable JSON metadata, Shortcuts and optional Mac MCP access

Good for

  • Readers managing authorized PDFs with independent backups

Privacy & permissions
