Overview
Logseq began as a personal project by developer Tienson Qin to build an outliner that stores interconnected notes as plain-text files a user fully owns, launching publicly around October 2020 before Qin co-founded Logseq Inc. with An Vu, Huang Peng, and ZhiYuan Chen.
The project raised over 4.1 million dollars in seed funding from investors including Patrick Collison, Tobias Lütke, and Nat Friedman, and remains free, open source, and licensed under AGPL-3.0.
Key Features
Logseq combines a block-based outliner with bidirectional linking, daily journaling, a query language for dynamic views, whiteboards, PDF annotation, and built-in flashcards with spaced repetition.
All data is stored locally as Markdown or org-mode files, giving users full ownership and portability of their notes independent of the app itself.
Pricing
The core Logseq application is completely free and open source with no feature paywall, since the codebase is publicly available on GitHub under the AGPL-3.0 license.
Logseq monetizes through an optional paid Sync service that keeps a user's graph synchronized across multiple devices, while local-only use remains free indefinitely.
Key Features
Block-based outliner — Every line is a nestable, linkable block, allowing notes to be organized hierarchically or as a network of ideas.
Bidirectional linking — Pages and blocks link to each other automatically, with backlinks surfaced so related notes are easy to rediscover.
Local-first plain-text storage — Notes are stored as Markdown or org-mode files on the user's own device rather than a proprietary database.
Daily journal — A journal entry is created automatically each day as the default capture point for thoughts and tasks.
Query language — Dynamic queries build live views of tagged or linked content across the entire graph.
Whiteboards — Visual, spatial canvases for mapping ideas alongside the text-based outline.
PDF annotation — Highlight and annotate PDFs with links back into the linked note graph.
Flashcards and spaced repetition — Converts tagged notes into a built-in study system for active recall.
