Superscribe

Build me a push-to-talk dictation tool for macOS to replace Superscribe's desktop app. Requirements: - Swift menu bar app, SPM only, no Xcode project. A global hotkey (default: hold Option+Space) records while held, stops on release. - Capture the mic with AVAudioEngine, downsample to 16kHz mono PCM, and stream it over WebSocket to ElevenLabs Scribe realtime (key in .env). Show partial transcripts in a small floating panel while I speak. - On release, run one LLM cleanup pass over the final transcript (fix punctuation, drop filler words; key in the same .env), then paste it into the focused app via NSPasteboard + CGEvent Cmd-V and restore my previous clipboard afterwards. - Fallback: with no ElevenLabs key, record to a temp wav and transcribe locally with whisper.cpp instead. Slower is fine. - Menu bar icon shows idle/recording/transcribing states; a history window lists the last 20 transcripts with copy buttons, persisted to ~/Dictation/history.jsonl. - Ad-hoc codesign for my own machine only. README documents the Microphone and Accessibility permission prompts and the whisper.cpp model download. - Out of scope: live word-by-word typing into the field (paste on release only), Windows support, accounts and billing, and the phone-call capture product. If I want call notes I will upload recordings by hand.
