What is Grok STT?
Grok STT (speech-to-text) is a large-scale automatic speech recognition model developed by xAI, the AI lab founded by Elon Musk. Released in April 2026, it is one of the most accurate open-endpoint transcription APIs available, with particular strengths in noisy audio, accented speech, and long-form recordings.
ScribeForge is the first dedicated web service to offer Grok transcription online — no need to build your own API integration, sign up for xAI access, or manage API keys.
