Every note is a plain .md file in a folder — switch editors, back it up, put it in git. No proprietary format, no lock-in.
Built-in AI assistant (DeepSeek, no API key): @file references, file read/write agent, conversation history, summarize-to-note.
Declarative plugins for rendering & templates (keycaps, mentions, quote cards, terminal blocks, report/PRD templates).
Offline render: markdown-it, KaTeX, Mermaid, highlight.js. Native SwiftUI + AppKit, no Electron. macOS 14+.
