What's New Since 0.4.0
ChatGPT OAuth Sign-In
- Sign in with your ChatGPT Plus/Pro subscription for meeting summarization — no API key needed
- Browser-based OAuth with PKCE, tokens stored securely in macOS Keychain
- Model selection: GPT-5.2, GPT-4.1 Mini/Nano, GPT-4o
Speaker Diarization
- Meeting transcripts now identify individual remote speakers (Speaker 1, Speaker 2, etc.) instead of generic "Others"
- Powered by FluidAudio's pyannote-based CoreML diarization model running on Apple Neural Engine
- Automatic speaker label assignment in first-appearance order
VAD-Driven Chunk Rotation
- Meeting mic audio now splits at natural speech boundaries using Silero VAD streaming detection
- Replaces fixed 30-second chunks — no more mid-sentence cuts
- 3s minimum / 60s maximum chunk duration safety rails
Camera-Based Meeting Detection
- Webcam turning on instantly triggers meeting detection notification
- Event-driven via CoreMediaIO — no polling, zero latency
- Strongest detection signal: camera on = meeting, regardless of which app
New ASR Models
- Qwen3 ASR — 52 languages, ~900MB (int8), 2-3s latency. Warmup inference during preload eliminates 30s first-run penalty.
- Nemotron Streaming (Experimental) — NVIDIA RNNT streaming model. English-only, best for hands-free mode with 10s+ utterances. ~0.3s warm latency. Live text-at-cursor in handsfree mode.
Dictation History
- Infinite scroll — see all your dictations, not just the last 50
- Dynamic date filtering: Last 2 days, Last week, Last month, etc.
- Filter options appear based on your actual data range
Build & Distribution Fixes
- Sparkle.framework properly bundled and deep-signed (all nested binaries)
- App notarization working — signed, notarized, and stapled by Apple
