Build a personal knowledge graph where every note is a typed, interconnected node — turning your notes into a queryable second brain.
Each app below addresses a specific gap in Tana's offering. We picked them based on real user review patterns and feature differentiation.
Roam Research pioneered the bidirectional-link knowledge graph approach and has a loyal power-user community around its outliner-first format.
Explore Roam Research data →Obsidian stores notes as local Markdown files with bidirectional links and a large plugin ecosystem, prioritising data ownership and offline access.
Explore Obsidian data →Logseq is an open-source, local-first outliner with bidirectional links and a block-based graph, combining Roam-like linking with privacy-first storage.
Explore Logseq data →Notion combines notes, databases, wikis, and project management in a highly flexible workspace, sacrificing the graph-link model for broader use cases.
Explore Notion data →Heptabase places notes on a visual whiteboard canvas, supporting spatial organisation of knowledge cards alongside traditional note-taking.
Explore Heptabase data →Capacities organises notes as typed objects — books, people, projects — with relationship linking similar to Tana's typed node approach.
Explore Capacities data →Knowledge workers who outgrew Roam Research or Notion's flexibility migrated to Tana for its structured typing system, which makes notes machine-readable and queryable.
Tana has a mobile app available on iOS. Mobile functionality has been expanding, though the full power of supertags and AI commands is primarily designed for desktop use.
Both use bidirectional links and an outliner model, but Tana adds typed supertags that create structured schemas for notes, making them queryable like a database. Roam has a larger existing community and more mature plugin ecosystem.
Tana is primarily designed for individual knowledge work. Collaborative features exist but are less mature than team-first tools like Notion or Confluence.
