Features
- Library
- Switch between grid view (large and small) and list view. Sort and filter to find what you want to read.
- Folders, Categories & Tags
- Use your iCloud folder structure as-is. On top of that, organize freely with shelff's own categories and tags.
- Metadata Editing
- Edit title, author, publisher, language, description, and more. Automatic import of metadata embedded in PDF files is also supported.
Your Data
- Everything Lives in iCloud
- Not just your PDF files — metadata and reading progress are also stored as JSON files in iCloud. If you're signed in with the same Apple ID, your reading progress and metadata sync automatically across devices.
- Open Metadata Format
- Metadata is stored as JSON files in iCloud in an openly specified, portable format. Other tools can read and write it alongside shelff.
- Organize your library with an AI Agent and the MCP Server
- On any Mac signed in with the same Apple ID, you can search and organize your PDF library using an AI agent and shelff-mcp.
