Sites demo builds a ChatGPT-signed social app with profiles, feeds and DMs

A demo shows Sites building a social app prototype with ChatGPT sign-in.

The requested app is basically a Twitter clone with profiles, a feed, DMs, image uploads, following/follower dynamics, and a for-you / following split.
The screenshot shows the system iterating on the build and listing missing product pieces such as onboarding, handles, likes/replies/reposts, notifications, search, moderation, unread counts, and privacy.
The post frames the core idea as a browsable app with sign-in for actions plus fast private messaging.
