TypeWhisper is a macOS application that performs local speech-to-text transcription using on-device Whisper models (WhisperKit), keeping voice data private on the user’s Mac. It optionally integrates with cloud LLM APIs (OpenAI, Groq, xAI/Grok) for AI text processing. The app provides system-wide dictation, file transcription, reusable workflows for text transformation, history, snippets, and a plugin SDK for extensibility.
