Local speech-to-text with the Whisper CLI (no API key)

openai-whisper is an agent skill from the OpenClaw project, listed on skills.sh. It transcribes audio on your own machine with the Whisper CLI, with no API key: pick a model for speed or accuracy, write plain text or subtitles, and translate speech to English. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
