Notesnook vs TriliumNext Notes

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.

TriliumNext Notes is a free, open-source application for taking notes and maintaining a personal knowledge base. It uses an outliner structure in which notes can be nested hierarchically and placed in multiple locations. Supported note types include text, Markdown, code, spreadsheets, canvases, Mermaid diagrams, mind maps and files. Collections can present the same material as calendars, tables, Kanban boards, geomaps, presentations or dashboards. Full-text search can inspect image and PDF text through OCR. Notes can be imported from Markdown, HTML and OPML and exported to those formats. Self-hosted or cloud instances synchronize across devices and provide mobile browser access through a PWA; no official mobile app is provided. JavaScript supports widgets and scheduled or event-driven scripts. Optional AI connections use your own provider keys. Protected notes use AES-128 CBC, while metadata remains unencrypted. The software is designed for one user, not simultaneous shared editing.
