Your library is the central hub for all your reading content. Organize reads across custom libraries, search your collection, and keep progress synced across devices with Pro cloud sync.

Library Overview

Every read you add lands in your Inbox by default. From there, you can organize content into custom libraries that match your workflow.

Default Libraries

Rapid Reader starts with four libraries:
LibraryPurpose
InboxLanding zone for all new content (always visible, cannot be deleted)
ArticlesWeb content, news, blog posts
BooksEPUBs and longer-form content
DocsPDFs and other document files

Custom Libraries

Create up to 6 libraries total with custom names and icons. Each library can use an emoji or a Lucide icon as its label, so you can tell them apart at a glance. To create a library, open the library settings panel and add a new one. Rename, reorder, or delete libraries as your reading habits change.

Categorization Modes

Control how new content is sorted when it arrives:
ModeBehavior
Auto-categorizeContent is sorted by source type — EPUBs go to Books, PDFs to Docs, web content to Articles
ManualEverything goes to Inbox. You decide where each read belongs
Switch between modes in Preferences > Library.

Organizing Reads

Keep your library tidy with these features:
  • Drag and drop — Reorder items by dragging them to a new position
  • Move between libraries — Reassign reads to different libraries when editing
  • Search — Press S to filter your library by title
  • Bulk select — Hold Shift and click to select multiple items
The search filter matches against titles in real-time. Press Escape or clear the search field to show all items again.

Progress Tracking

Each read tracks your position automatically:
  • Auto-save — Progress saves every 5 seconds during playback
  • Manual save — Press Ctrl/Cmd+S to save at any time
  • Progress bar — Shows percentage complete for each read in the library
  • Chapter position — For EPUBs and Markdown with chapters, your chapter position is tracked

Storage and Sync

Local Storage

Rapid Reader stores content locally on your device by default.
PlatformStorage Limit
Web app~5MB (browser localStorage)
Desktop appNo practical limit
Web app users: Clearing your browser data, cookies, or site storage will permanently delete all your reads and progress. Consider using the desktop app for a large library, or upgrade to Pro for cloud backup.

Cloud Sync (Pro)

Pro users get bidirectional cloud sync that keeps reads and settings in sync across all devices.
  • Automatic — Changes sync in the background every 30 seconds
  • Conflict resolution — When edits happen on multiple devices, the most recent change wins
  • Login behavior — When you sign in on a new device, your cloud library replaces the local one
Cloud sync covers your reads, reading progress, library organization, and appearance settings.

Backup and Export

Protect your library with the built-in backup system:
  • Export — Download your reads as a JSON backup file from Preferences > Account
  • Import — Restore from a backup file with automatic duplicate detection
  • Duplicate handling — If a read already exists (matched by content hash), progress is merged rather than creating duplicates
