Turtl: The secure, collaborative notebook | Turtl
The safe way to remember everything. Take all your important data with you.
Categories:
Turtl is a secure, open-source notebook for organizing notes, bookmarks, passwords, files, and more with end-to-end encryption and collaboration across devices.
🚀 Overview
Turtl is a privacy-focused note-taking and organization app that lets you store and sync personal data like bookmarks, passwords, shopping lists, files, and documents securely across devices. It uses client-side, end-to-end encryption derived from your email and password, ensuring no one—not even the server operators—can access your data without your credentials.
The project solves the problem of insecure cloud note apps (like Evernote) that expose data to surveillance, hacks, or leaks. It provides a secure alternative with collaboration via 'Spaces' for sharing with teams or individuals, full-text search, and self-hosting options for ultimate control.
Built for privacy-conscious individuals, researchers, teams, and anyone organizing sensitive info. It was created as a community-driven, open-source response to the need for a truly private notebook, with core library audited for security.

- Rich Note Types & Editing: Supports text, bookmarks, passwords, images, files/documents; Markdown editing with TeX math rendering ($$), tags, full-text search by text/date.
- Cross-Platform Access: Desktop apps (Windows, macOS, Linux), Android app, browser extension for bookmarking; semi-offline mode, keyboard shortcuts, multi-language/RTL support.
- Self-Hosting & Extras: Open-source server for self-hosting; profile backups, client-side crypto protecting against leaks/surveillance.
