When to use
Optimised for: personal-knowledge-management UX + AI-augmented note-taking
Anti-fit: not for enterprise / programmatic use; not for compliance-regulated workloads
Pros & cons
Pros
Open-source PKM with block-graph model; memory benefits from explicit knowledge-graph structure.
Cons
Less mature AI integrations than Notion / Obsidian; community-driven so velocity varies.
Claims & capabilities
Open-source local-first PKM in active community; common comparison anchor against Tana / Obsidian / Roam in 2025 PKM space; daily-notes + outliner block model; users often pair with Tana as complement vs primary tool
