Turtl is an open-source, secure, and collaborative digital notebook designed to protect user data while organizing personal and team notes.

The main features and capabilities of Turtl include:

• High-End Cryptography & Data Security: Protects your notes using high-end cryptography so that only you and those you authorize can access your data, shielding it from information leaks, competitive monitoring, and blanket government surveillance. Its core library has also undergone a security audit.

• Multi-Device Content Organization: Organizes diverse data types—including bookmarks, passwords, files, and shopping lists—while keeping everything synced across all your devices.

• Collaborative Sharing via Spaces: Enables secure sharing with family members or team members without compromising end-to-end security using dedicated Spaces.

• Markdown Formatting & Search: Supports note writing in Markdown format and allows quick searching using text queries or tags.

• Open Source & Self-Hosting: Maintained as an open-source community project by Lyon Bros LLC, giving users full access to inspect the codebase on GitHub and the freedom to run their own Turtl server at home or in the workplace.

• Flexible Service Options: Offers a self-hostable community version alongside a premium service tier and donation options to support development.
