A macOS desktop app that records meetings, transcribes them, and produces structured notes — with action items pushed directly as GitHub issues and notes committed to a git repository.

Built with Tauri + Svelte 5 on the frontend, Rust on the backend.

1. Records two audio streams in parallel — local mic and remote source (system audio via BlackHole) — with live dual VU meters
2. Transcribes live both streams in real time using local whisper.cpp with Metal GPU acceleration — no audio leaves your machine. VAD (Silero) detects speech boundaries and feeds chunks to Whisper as you speak, so the transcript appears during the meeting.
3. Merges the two transcripts into a single time-sorted conversation, each segment labelled with the correct speaker name (one stream = one speaker, no diarization needed)
4. Summarizes with Claude Sonnet (Anthropic) or any Together.ai chat model, using a context you define (meeting type, participants, domain vocabulary)
5. Exports structured Markdown notes (YYYY-MM-DD_HHmm_Context.md) to a configurable folder
6. Commits the notes to a git repository automatically (optional)
7. Creates GitHub issues for every action item extracted from the notes (optional)

Privacy: All audio is processed locally on-device. Only the final text transcript is sent to the cloud for summarization (Anthropic or Together.ai). A Groq Whisper cloud fallback is available in settings if preferred.

Each meeting produces two files:

Meetings/
 2026年03月20日_1430_welqin.md ← structured notes
 2026年03月20日_1430_welqin_transcript.md ← raw transcript with named speakers

The notes follow a consistent structure:

## Participants
## Summary
## Key Discussion Points
## Decisions Made
## Action Items
- [ ] **David**: Review the API design document
- [ ] **Yannick**: Set up CI pipeline for staging

Action items are automatically created as GitHub issues with the meeting-action label.

• macOS Apple Silicon (M1 or later — Metal GPU required for local Whisper)
• BlackHole 2ch — virtual audio driver for capturing system audio (see setup guide)
• cmake — required to build whisper.cpp (brew install cmake)
• One of (for summarization):
  • Anthropic API key — to use Claude Sonnet
  • Together.ai API key — to use open-source models (Llama, etc.)
• gh CLI installed and authenticated — for GitHub issues (optional)
• git — for committing notes (optional)
• Groq API key — only if using cloud transcription fallback (optional)

The Whisper model (large-v3-turbo, quantized q5_0, ~550 MB) is downloaded automatically on first launch to ~/.sidekick2000/models/.

npm install

Launch the app and click the gear icon in the top-right corner. All settings are stored in ~/.sidekick2000/settings.json.

API keys set in Settings take priority over environment variables. You can still use a .env file as fallback.

npm run tauri dev

npm run tauri build

Contexts are the core of Sidekick2000's flexibility. Each context is a Markdown document that gives Claude background knowledge about a meeting type: who the participants are, domain vocabulary, and how to structure the notes.

Examples of contexts you might create:

• General — neutral instructions, works for any meeting
• Product review — focus on decisions, feature requests, backlog items
• Client call — highlight commitments, risks, next steps
• Training session — track exercises, Q&A, shortcuts mentioned

Contexts are managed entirely in the Settings UI (no external files needed).
