Logseq
Privacy-first outliner for notes and tasks that stores Markdown or Org-mode files, with PDF annotation and plugins.
Outline notes, tasks and PDF highlights in Markdown or Org-mode, with a new database version in beta.
Logseq is a privacy-first knowledge management and collaboration platform for desktop and mobile. It supports Markdown and Org-mode files, task management and PDF annotation. It suits people who want an outliner for personal notes and are willing to follow a project in transition.
What it is
You write notes as blocks, link them, manage tasks and annotate PDFs. The classic version works from Markdown or Org-mode files, while the Database version adds DB graphs, a new iOS app and real-time collaboration sync that the README labels beta and alpha. A plugin API and themes extend the app.
Who it's for
It suits students, researchers and knowledge workers who like outlining and want control over their files. If you cannot risk data loss, hold off on the Database version: the README warns data loss is possible and recommends backups.

Our honest verdict
What's great
- Notes can live as Markdown or Org-mode files, so your content stays readable outside the app.
- PDF annotation and tasks sit in the same outliner as your notes.
- A plugin API and themes let you shape the app to your workflow.
- Desktop, a web build and mobile apps are all mentioned in the README.
Where it falls short
- The Database version is in beta and its README warns that data loss is possible, recommending automated backups or SQLite exports.
- The new mobile app and RTC sync are alpha and require you to sign up through forms to participate.
- The README splits current work between the classic app and the DB version, so you must choose which graph type to commit to.
- Linux users are pointed to an install script that you run with curl and bash, or you can use the user-specific install option.
