Logseq
FreemiumOpen-source outliner-first note app with local markdown files, block references, and a growing plugin ecosystem
What is Logseq?
Logseq is a free, open-source note-taking app often described as a "local-first Roam clone" — it offers the same networked-thought workflow as Roam Research (daily notes, bidirectional links, block references, queries) but stores everything as local markdown files on your computer, which you can back up or sync however you want. Built by a small open-source community since 2020, Logseq has become the default choice for people who love Roam's mental model but want free software with local files and no vendor lock-in. The app runs on macOS, Windows, Linux, iOS, and Android, and syncs via iCloud, Dropbox, Git, Syncthing, or the paid Logseq Sync ($5/month, end-to-end encrypted). Logseq's feature set is impressive: daily journal-first workflow, outliner interface with nested bullets, bidirectional [[links]] and ((block references)), Whiteboards for visual thinking, a plugin system with hundreds of community plugins including AI integrations, PDF annotation, spaced repetition, flashcards, queries via Datalog, and Zotero integration for researchers. The free tier is the real app — unlike Roam there is no paywall. The only paid option is Logseq Sync, which funds the team. Logseq does not have first-party AI features but the plugin ecosystem includes AI chat, semantic search, and Ollama integration for local models. For researchers, academics, and privacy-focused knowledge workers who love outliners but hate subscriptions, Logseq is often the top choice.

FAQ
Is Logseq really free?
Yes — completely free, open source, with no feature limits or ads. The entire app including daily notes, block references, whiteboards, plugins, PDF annotation, and queries is free forever. The only paid option is Logseq Sync ($5/month), which is an optional convenience service for cross-device sync. If you use iCloud, Dropbox, Git, or Syncthing to sync your notes folder, you never need to pay anything for Logseq.
Logseq vs Roam — which is better?
For most users, Logseq is the better choice in 2026. It offers the same core features as Roam (daily notes, block references, bidirectional links, queries) but for free with local markdown files. Roam is more polished and has slightly better sync and mobile apps, but it charges $15/month and stores your data in the cloud. If you love the Roam workflow and want to save $180/year while owning your files, Logseq is the clear pick.
Logseq vs Obsidian — which is better?
Different mental models. Obsidian is document-first (full markdown files per note) while Logseq is outliner-first (every note is a tree of bullets with block references). Obsidian has a bigger plugin ecosystem and more polished UI. Logseq has better native daily-note workflows and block references built into the core. Pick Obsidian if you write long-form documents. Pick Logseq if you think in outlines and daily entries.
Does Logseq have AI?
Not as a first-party feature, but through plugins. The Logseq plugin marketplace includes several AI plugins: Logseq Copilot (ChatGPT integration), Logseq AI Assistant (various LLMs), semantic search plugins, and Ollama integration for 100% local LLMs. Setup takes 10-15 minutes and requires your own OpenAI or Anthropic API key, similar to how AI works in Obsidian. Not as polished as Notion AI but fully functional.
Does Logseq sync between devices?
Yes, several ways. The easiest is Logseq Sync ($5/month, end-to-end encrypted, managed by the Logseq team). Free options include iCloud Drive (Mac+iOS), Dropbox, Google Drive, OneDrive, Syncthing, and Git. Whichever method you choose, your notes remain local markdown files on each device, synced through the underlying file sync service. Power users often choose Git for free versioned sync.
Is Logseq good for teams?
Not really. Logseq is primarily a personal knowledge tool. There is no built-in real-time collaboration, shared workspaces, or permission management like Notion. You can share a Logseq graph via Git and have a team work on the same markdown files, but conflicts and merge headaches are common. For teams, Notion, ClickUp, or Tana are better.
Is Logseq reliable?
Yes for desktop use, mostly yes for mobile. The desktop apps (macOS, Windows, Linux) are mature and stable, actively developed by a small but dedicated open-source team. The mobile apps (iOS and Android) have historically been less polished but have improved significantly in 2025-2026. If reliability is critical, back up your notes folder with Git or a cloud sync service — which is standard practice for Logseq users anyway since files are plain markdown.
📋 Good to know
Download from logseq.com, choose a local folder for your graph (or iCloud Drive for Mac+iOS sync), start writing. Optional plugins via Settings → Marketplace.
Best-in-class for notes. Files are local markdown. Open source under AGPL. Optional Sync is end-to-end encrypted. Can run with 100% local AI via Ollama plugins.
Nothing required — app is fully free. Optional Logseq Sync ($5/mo) for convenient cross-device encrypted sync if you don't want to manage Git or iCloud yourself.
Moderate. Outliner basics are immediate. Queries, plugins, and advanced workflows take a few weeks to master.
