xAI / Grok adds Grok-powered cloud speech-to-text, prompt processing, and text-to-speech to TypeWhisper for macOS. The plugin uses an xAI API key for every capability and stores the key securely in the macOS Keychain.

Speech-to-Text

API Key
Stores and validates the xAI API key used by STT, LLM, and TTS features.
