    About

    In practice. What you can do with Logseq.

    Logseq is a local-first, open-source personal knowledge management app built around a bidirectional-linking knowledge graph and outliner. Notes are stored as plain markdown files on the device, and an optional cloud Sync (currently in beta) adds multi-device access with experimental Smart Merge for simultaneous editing.

    The core app is entirely free. Sync access during beta runs through a recurring Open Collective contribution: $5/month unlocks synced graphs (10 per account, 10GB each), $15/month adds Whiteboards. It fits a developer or technical solo worker who wants full control and portability of their notes rather than a cloud-locked app.

    Practical uses

    • CaptureBuild a linked knowledge graph of project notes and ideas locally, free, without any cloud dependency.
    • SyncAccess the same graph from a laptop and a phone by contributing to the Backer tier of Sync (beta).

    • Available across desktop, iOS and Android for the same knowledge graph.

    Against. What to plan for.

    Our verdict. What to know about Logseq.

    How the score breaks down

    Added value

    The core knowledge graph app is fully free and open source, with cloud sync available for a small recurring contribution during beta.

    Simplicity

    The outliner and bidirectional linking take some learning to use well, and Sync setup adds an extra step via Open Collective.

    Fit for purpose

    Delivers local-first note-taking and knowledge graphing as promised across desktop and mobile platforms.

    Performance

    Solid knowledge graph and outliner, but Whiteboards and reliable multi-device sync require the paid Sync tiers, and Smart Merge is still experimental.

    Reversibility

    Local-first, open-source app storing notes as plain markdown files gives full data ownership and easy export.

    AI. What it changes for Logseq.

    AI augments this tool

    Go further with AI

    Logseq remains an open-source, local linked-notes system, with third-party AI plugins gradually being added without changing its philosophy of networked thinking and data ownership.

    Can AI replace it?

    Replace Logseq with an AI? No: Logseq's value is keeping notes local, self-structured over time — a personal thinking system AI isn't meant to replace. Verdict: AI augments note usage, the thinking system remains personal.
