Turtl

Turtl is a secure, open-source notebook designed to help users organize and protect their digital information. It allows for the storage and synchronization of various data types, including bookmarks, passwords, files, and notes, across all devices. A core tenet of Turtl is its robust security, employing high-end cryptography to ensure that data remains private and accessible only to the user and their chosen collaborators.

The tool's value proposition lies in its combination of strong privacy features with practical organizational and collaborative capabilities. Users can create 'Spaces' to categorize and share content, and notes can be written using Markdown for easy formatting. For those seeking ultimate control, Turtl offers the option to self-host its server, reinforcing its commitment to user data sovereignty. Its open-source nature also invites community contributions and allows for transparent security audits.
