What is Logseq?

Logseq isn't just another note-taking app—it's a fundamental rethink of how you capture, connect, and retrieve knowledge. Built on open-source principles and radical privacy, this platform puts you back in control of your data. Everything you write lives as plain markdown or Org-mode files on your local machine, so you're...

How to Use Logseq

Getting started with Logseq is straightforward. This guide will walk you through installing the app, creating your first notes, and building a connected knowledge base using bidirectional links.

Install Logseq and Create Your First Graph

Download Logseq from the official website or your device's app store. On first launch, you'll be prompted to create a new graph (a collection of your notes). Choose a local folder where all your files will be stored. Logseq automatically creates the folder structure and your first daily journal page.

Take Notes with the Daily Journal

Your daily journal is the default landing page and acts as an inbox for quick capture. Write thoughts, ideas, or tasks using markdown bullet points. Each entry is timestamped and auto-saved. Use indentation to organize your thoughts hierarchically—this becomes the foundation of your knowledge base.

Link Notes with Bidirectional References

To connect ideas, type [[ followed by a page name. Logseq will create a new page or link to an existing one. The linked references section at the bottom of each page automatically shows all other pages that mention it. This two-way connection grows your knowledge graph organically.

Organize with Tags, Queries, and Plugins

Use #tags to categorize notes across your graph. For advanced organization, write queries using Logseq's Datalog-based query language to generate dynamic tables and dashboards. Browse the plugin marketplace (150+ options) to add features like calendars, kanban boards, or AI assistants.
