What it does

Logseq is a desktop app for taking notes and organising what you know. You write in short bullet points, link pages to each other, keep task lists and highlight PDFs, and the app shows how your notes connect. It is for students, professionals and anyone who keeps a lot of notes. There are ready installers for Windows and Mac, an AppImage or install script for Linux, and a web version, plus plugins and themes. The new database version is in beta and the project itself warns that data loss is possible, so it recommends backups.

Windows and Mac are the easiest: a ready installer (Logseq-win-x64-2.0.2-nsis.exe, about 146 MB) or a .dmg that you download, install and start writing in. On Linux the release gives an AppImage you must make runnable yourself, or the README's one-line install script. The web version at app.logseq.com needs no install but is the beta database version.

What Radar could not check

Whether notes made in the older file-based version open correctly in the new database version.
Whether the app sends usage analytics, and whether that can be switched off.
How stable the 2.0 releases are on Windows with large note collections.
Whether real-time sync will stay free after the alpha.
