Wispr Flow

Build me a system-wide AI dictation tool like Wispr Flow for macOS. Requirements: - A background app with a global hotkey (hold-to-talk fn key or a chosen shortcut). While held: record the mic. On release: transcribe and paste. - Double-tap the hotkey for a hands-free session that records with nothing held · one more tap stops it. Auto-stop after 5 minutes so a forgotten session cannot record all afternoon. - Esc cancels: drop the recording, or kill a transcription already running. Watch it passively so Esc still reaches the app I am typing in. - Transcribe with whisper.cpp locally (small or medium model), or the Groq/OpenAI Whisper API if a key exists in .env · pick per a config flag. - Pipe the raw transcript through an LLM (key in .env) with a short prompt that removes filler words, fixes punctuation, and matches casing to dictation style. - Insert the result at the current cursor position in whatever app has focus (simulate keystrokes or use the pasteboard + Cmd-V approach). Leave the transcript on the clipboard so I can paste it again, with a config flag to restore my previous clipboard instead. - Show a tiny floating pill while recording so I know it's live and which mode I'm in. - Menu bar toggle for on/off, launch at login, and a settings file for the hotkey. - No accounts, no telemetry, works offline with the local model. - README with the Accessibility/Input Monitoring permissions I need to grant.
