## Description

Build your PDF bookshelf on iCloud. Organize with folders, categories, and tags. All metadata is stored as files — your data is always yours.

shelff is a reading app for browsing and managing PDFs stored in iCloud.

All your data lives in iCloud Documents. You are never locked into a proprietary database. Metadata is saved as JSON files alongside your PDFs, so even if you stop using the app, your data remains yours.

  - Filter by categories and tags
  - Group multi-volume works and magazine back issues into collections, with custom ordering
  - Sort by title, author, date added, or last read
  - Filter by reading status (unread, reading, finished)
  - Full-text search across your PDFs
  - Switch between grid and list views

  ■ PDF Reader
  - Immersive full-screen reader
  - Single page, two-up, and two-up with cover layouts
  - Left-to-right (LTR) and right-to-left (RTL) support
  - Highlights with optional comments

  - In-document text search
  - Brightness adjustment

  ■ Metadata Management
  - Edit title, author, publisher, publication date, and more
  - Auto-extract initial values from PDF metadata
  - Automatic reading status transitions (starts reading, finishes at last page)

  ■ Data Transparency
  - All data stored as files in iCloud Documents
  - Metadata in JSON, annotations in the PDF itself
  - Accessible anytime from the Files app
  - You can search and organize your JSON metadata on iCloud using an AI agent and shelff-mcp on you Mac.
