Turtl

Turtl is a collaborative notebook for organizing bookmarks, passwords, files, shopping lists, and other notes. It supports text, bookmark, password, image, and document notes, with full-text search, tag filtering, Markdown, and TeX math rendering. Users can create Spaces, choose collaborators, and set permissions from read-only access through full ownership. Turtl says data is encrypted in the app before leaving the device, using keys derived from the user's email and password. Shared items get separate random keys, so recipients can unlock only the item shared with them. The service warns that an intercepted email invitation could expose a shared Space if its secret is not communicated separately. Users can import or export their full profile for backup or migration, and can install the open-source server to host their own data. Listed platforms include Windows, macOS, Linux, and Android, with Chrome and Firefox bookmarking extensions; offline access is supported. Premium costs $3/mo and includes 10GB note data and 10 collaborators per Space; Business costs $8/mo and includes 50GB and dedicated support.
