Slack sounds like Slack. Gmail sounds like email. Terminal gets clean commands. 18 built-in rules — write your own, or describe what you want and the AI generates the rule. 🔒 Fully Local Run everything on-device: Whisper or Qwen3-ASR for speech recognition, local LLM for rewriting. Audio never leaves your Mac. You can verify it — the code is here. 🗣 Speaker Diarization Meeting mode transcribes continuously in the background. Transcripts are labelled by speaker with timestamps. Import existing audio files for retroactive transcription. ✏️ Edit by Voice Select any text, press Option+E , say what you want done. \"Make this more formal.\" \"Translate to Japanese.\" \"Shorten it.\" The AI rewrites and pastes back. ☁️ Cloud or Local — Your Choice BYOK for everything: Groq, OpenAI, Deepgram, Azure, Gemini, OpenRouter, or any OpenAI-compatible endpoint. No Sumi account. No subscription. 🌏 58 UI Languages The interface ships in 58 locales.
