About XFastest
XFastest (xfaste.st) is a growth tool for X (Twitter) — it reads a founder's own voice, surfaces high-performing posts worth learning from, drafts new posts to match, and helps track and schedule them.
What we made
A ~70-second narrated product walkthrough of XFastest's entire first-run experience. It covers signup, connecting an X account, adding a product URL, and confirming a voice, then the Inspiration, Studio, Followers, Creators, and Calendar screens inside the app. Built screen for screen from XFastest's real UI — not a mockup — with a cursor clicking real, measured positions and full sound design throughout.
Frequently asked questions
Is this XFastest's real product?
Yes. Every screen — onboarding, Inspiration, Studio, Followers, Creators, and Calendar — is reconstructed from XFastest's actual UI, not a mockup or a generic template.
What kind of video is this?
A narrated product walkthrough — the kind of video XFastest can use in its own onboarding, on its homepage, or in a Product Hunt launch.
