Notesnook vs Turtl

Notesnook is a note-taking app for web, Windows, macOS, Linux, iOS, and Android, with note sharing and offline access. Notes are encrypted end-to-end before leaving the device, and the apps and sync server are open source under GPLv3. The app can be locked with a fingerprint, PIN, or password; selected private notes can also have a separate password. Individual notes can be published as web pages, optionally password protected. Zapier, IFTTT, or a custom script can send notes through the Inbox API. The free plan offers unlimited notes on unlimited devices, 50 MB of attachment storage per month, files up to 10 MB, and limits of 50 notebooks and 50 tags. Free users can read web-clipped content offline; paid plans include full offline mode and provide from 1 GB to 25 GB of attachment storage per month. Monthly plan prices listed include Essential at $1.99 per month, Pro at $6.99 per month, and Believer at $8.99 per month, including tax. Subscriptions can be cancelled without fees, with notes remaining readable and exportable.

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.
