01One take

Record once. Get the video and the words. Same run.

The video, its captions and a list of every page visited all come from one recording. Nothing to sync, nothing to retype, nothing to cut.

H.264 + AAC. Captions are embedded in the MP4 and shipped as a file.

02Behind the login

Records the pages only users see. Your password never hits disk.

Walkcast finds the sign-in form, including two-step email-then-password flows, signs in with what you give it, and walks the signed-in site.

  • You confirm the site

    Every recording asks you to say you own the site or may test it. No confirmation, no recording.

  • A placeholder, not a password

    Traces, captions and files show a placeholder. The narration says a password was entered and never reads it out.

  • No bot-check games

    It never tries to get past a CAPTCHA, bot check or second-factor prompt. It stops and tells you.

  • Looks, never touches

    No form submissions. Sign-out, delete, cancel and unsubscribe links are skipped.

03Narration

Every page.
One voice-over.

Lines are written from what the browser actually did: the page it opened, the field it typed into, what the site answered. Nothing is made up.

Walkcast is a free, open-source Windows app that makes a narrated video walkthrough from a website link. A real browser signs in, visits up to 30 pages on that site, and returns an MP4 with a spoken voice-over, WebVTT captions and a transcript. Every line of narration comes from what the browser actually did.

Your site has pages.
Now it has a voice.
