MarkNote — Local-first Markdown Notes

What it does

Every note is a plainmd 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+.

A local-first Markdown notes app for macOS - files are the storage. AI assistant (DeepSeek) & declarative plugin system. Offline render pipeline. - yunsu-coder/suishou
