A familiar Markdown notebook built in Rust: local vaults, live/source/reading modes, note links, backlinks, search and global/local graphs. Your notes stay ordinary Markdown files.

What works today
Tasks, tables, colored highlights, callouts and native Mermaid; daily notes, templates, bookmarks, workspaces and recovery snapshots. Open an existing file or folder through the File menu.
Speed, with evidence
A paired 100-note warm-start test measured the verified baseline at a median 0.61 s, versus 3.77 s for Obsidian 1.14.4 on the same host. This bounded software-display benchmark predates the later graph update; it is not a universal speed claim. Method, versions and original evidence.
Help build the rest
This is an early Linux alpha. Full Obsidian feature and visual parity remain unfinished; existing Obsidian JavaScript plugins are unsupported. See the roadmap. Rust/egui, Markdown, accessibility, platform and testing contributions are welcome.
