ctLibrary
Offline documents and notes
Free · Designed for iPad. Not verified for macOS.
ctLibrary is a free offline-first document and notes library. Keep PDFs, Word, Excel, PowerPoint, images, text files, and your own typed notes organized in one place — on your device, and optionally synced across your Apple devices through your own iCloud account.
ORGANIZE
- Folders contain Categories. Categories contain documents and notes together.
- Personal folder with Important Documents and Personal Notes categories, ready on first launch. Create your own folders and categories anytime.
IMPORT DOCUMENTS
- Import PDFs, Word, Excel, PowerPoint, images, text, CSV, RTF, and Markdown.
- Share into ctLibrary from Mail, Files, Safari, cloud-drive apps, and more.
- Manual import from the Files picker also supported.
READ, SEARCH, SHARE
- Open PDFs directly in the app with pinch-to-zoom and pagination.
- Preview images, text, and CSV files in-app.
- Best-effort preview of Office files; fall back to Open With for full editing.
- Fast offline search across document titles, descriptions, file names, and note text.
- Favorites and Recent Items for one-tap access.
NOTES
- Type quick notes alongside your imported documents.
- Notes search by title and body content.
- Combined view shows documents and notes together inside each category.
SYNC ACROSS YOUR APPLE DEVICES (OPTIONAL)
- Turn on iCloud Sync in Settings to keep your library in sync between your iPhone and iPad through your own iCloud account.
- Data stays in your iCloud account; Cozzitech operates no sync server and never sees it.
- Sync is off by default — your library can stay 100% on-device if you prefer.
OFFLINE-FIRST PRIVACY
- Everything stays on your device (or in your own iCloud, if you turn sync on). We never see your documents or notes.
- No analytics, no tracking, no advertising.
- Optional App Lock with biometric unlock and recovery code.
- Optional one-time email verification unlocks unlimited folders, categories, documents, notes, and outbound sharing.
ctLibrary is built for people who want a reliable local reference library — emergency-management binders, work procedures, household paperwork, training materials, or anything you want at hand without depending on a third-party cloud.
