Guidie is a browser extension that records a task once and automatically generates a complete how-to guide, including written step-by-step instructions, annotated screenshots, and a narrated MP4 video. It uses Claude to draft plain-language instructions from the recording, filling in steps live as the user watches. Privacy is built in by default: typed text is never captured, form fields are masked before screenshots, and sensitive on-screen details like emails and API keys are flagged for blurring. Guides can be shared with teammates, downloaded as video, and tracked with freshness tags to indicate when re-recording is needed.
