Who it's for

Writers, researchers, students, and knowledge workers who want to build a personal knowledge base or Zettelkasten-style note network without handing their notes to a cloud service — a privacy-focused alternative to tools like Roam Research or Notion.

What you get

An outliner where every note is made of nested bullet blocks, with bidirectional linking and a graph view that surfaces connections between notes automatically. Notes are stored as plain Markdown (or Org-mode) files on your own device, so there's no lock-in and you can sync or version them however you like (e.g. Git, Dropbox, or Logseq's own optional paid sync). It also supports journaling, task/TODO management, PDF annotation, flashcards for spaced repetition, and a plugin ecosystem for extending functionality.

How it works

You open or create a local folder as a 'graph,' and Logseq turns it into your workspace, starting each day with a journal entry where you jot down notes as outline blocks. Linking a note to another with [[double brackets]] creates a bidirectional connection that shows up as a backlink on both pages, and over time these links build a navigable knowledge graph.
