Portavoz 0.1.0 — knows who said what, locally

First public release. Portavoz records your meetings, transcribes them live, tells apart every voice — including yours — and summarizes everything 100% on your Mac. No cloud, no bots joining calls, no accounts.

Highlights

• Dual-channel capture — your mic and the meeting audio, never mixed: your words are yours by hardware truth.
• Live transcription under a second (Parakeet on the Neural Engine), with a one-click Whisper quality re-pass presented as a draft you approve.
• Speaker separation on-device (DER 7.6% on an AMI sample) with live S1/S2 labels and optional voice enrollment so "Me" follows you to any microphone.
• Summaries with three local engines: Apple Intelligence, Ollama, or the built-in Qwen3.5-4B (one 3 GB verified download, zero installs) — plus optional BYOK.
• Meeting intelligence: typed summaries (standup/1:1/planning/interview), meeting health, cross-meeting to-dos, a local RAG chat over your history, and an MCP server for your AI tools.
• Calendar-aware: pre-meeting briefs with cited "what to know", a heads-up banner, and recordings born with the real event name.
• Live Companion (opt-in): cards that answer factual questions the room just asked, and a ping when someone says your name.
• Audio first-class: synced lyrics-style player, channel-colored waveform, clips, AAC compression, drag-and-drop import.
• English/Spanish UI, mixed-language meetings preserved per speaker.
