Overview

Logseq stores notes as local Markdown/Org files but presents them as an outliner: every thought is a block, every block referenceable. The journal-first workflow (today’s page is home) suits research logging naturally, and built-in PDF annotation links highlights straight into your notes.

Why researchers use it

  • Block references — cite a single bullet from any note anywhere else
  • Journal-first — a daily research log emerges from normal use
  • PDF annotation — highlights become linked, referenceable blocks

Getting started

  1. Install Logseq and point it at a folder (it coexists with Git happily).
  2. Live in the daily journal; use [[links]] and #tags as thoughts arrive.
  3. Open a paper PDF in-app, highlight, and watch highlights become blocks.

The honest review

Strengths. Open source top to bottom, real data ownership, and the outliner model genuinely fits how research thinking fragments during the day.

Limitations. Smaller plugin ecosystem and slower development than Obsidian; performance degrades on very large graphs; the outliner-everything approach frustrates long-form prose drafting.

When NOT to use this If you write long connected essays in your notes app, the enforced bullets will fight you — Obsidian’s free-form pages suit prose thinkers better. Try both for a week; the outliner question decides it.
