Logseq

Logseq is an open-source knowledge base that puts privacy first. Your notes live as plain Markdown or Org files on your own device, so you own them fully. It works like an outliner: every bullet is a block you can link, tag, and move. Two-way links connect related ideas into a web you can explore. Students, writers, and researchers use it for journals, flashcards, and project notes. There is no account needed to start, and the code is open for anyone to inspect.

Key Features

1. Your Notes Stay on Your Device

Logseq saves notes as plain files on your computer or phone. No cloud is required, and no one else can read them.

2. Block-Based Outliner

Everything you write is a block. You can nest, move, link, and embed blocks to build clear, flexible outlines.

3. Two-Way Links

Link any page or block to another. Backlinks show every connection, so related ideas surface on their own.

4. Built-In Flashcards

Turn notes into flashcards for spaced repetition. Students use this to memorize facts without a separate app.

5. Powerful Queries

Ask Logseq to find notes by tag, date, or content. Simple searches work fast, and advanced queries dig deeper.

6. Whiteboards and Plugins

Sketch ideas on whiteboards and link them to notes. Community plugins add calendars, themes, and more.
