Show HN: Stik – Instant thought capture for macOS (open source, Tauri and Rust)


Hi, I built Stik because every note app wanted to be my second brain. I just needed something to catch a thought before it disappeared.

How it works:
Press [Cmd+Shift+S] from anywhere. A floating post-it appears. Type. Close. Back to work in under 3 seconds. Notes are saved as plain .md files in ~/Documents/Stik/.

What makes it different:
– No account, no cloud, no sync setup, no onboarding
– Notes are plain markdown files, open them in any editor
– On-device AI (Apple NaturalLanguage framework) for semantic search and folder suggestions, nothing leaves your Mac
– Built with Tauri 2.0 (Rust backend + React frontend), ~8MB binary
– DarwinKit sidecar handles NLP via a JSON-RPC bridge to Apple’s ML frameworks

Tech stack:
Rust, React 19, TypeScript, Tailwind, Tiptap editor, Swift (DarwinKit sidecar)

Install:
brew install –cask 0xMassi/stik/stik

I’d love feedback on the architecture, especially the Tauri + Swift sidecar pattern for accessing Apple-only frameworks from a cross-platform runtime.
