Walkcast is a free, open-source desktop app (Windows, macOS and Linux) that makes a video tour of your website from one link. A real browser signs in, visits up to 30 pages the way a first-time user would (8 by default) and returns the complete recording as an MP4 with WebVTT captions and a transcript. A voice-over is included when you add a voice key. Every caption comes from what the browser actually did.
