Obsidian vs Logseq: which is better in 2026
Short answer: both keep your notes as plain-text Markdown files on your own device. Pick Obsidian for a page-based knowledge base you can shape with community plugins and themes, a graph view, iCloud vaults and a Ukrainian interface. Pick Logseq for an open-source outliner where every block can be referenced and embedded, with tasks, flashcards for spaced repetition, queries, whiteboards and Zotero integration. Logseq’s App Store listing is not in Ukrainian.

Where your notes live
Obsidian works on top of a local folder of plain-text Markdown files and calls itself a second brain that stays yours, with iCloud vaults on iPhone. Logseq works on top of local plain-text Markdown and Org-mode files, so in both apps your notes are not locked inside the app.
How you write and link
Logseq is an outliner: you write in blocks, and any page or block can be referenced or embedded elsewhere, with backlinks and a knowledge graph tying it together. Obsidian is page-based, with a graph view of how notes connect, a customisable toolbar and pull-down quick actions on mobile.
Tasks, study and extras
Logseq builds in tasks and to-dos, flashcards for spaced repetition, powerful queries, whiteboards, an audio recorder and integrations with Zotero and YouTube. Obsidian grows through community plugins and themes, so you add only what you need.
Verdict
Pick Obsidian for a page-based knowledge base shaped by plugins and themes, with a Ukrainian interface. Pick Logseq for open-source outlining with block references, tasks and flashcards built in. Obsidian is also compared in Notion vs Obsidian, and more apps are in our guide to note-taking apps.
