After Elon Musk finalized his purchase of Twitter last October, Mark Zuckerberg’s Meta reportedly began working on a social media platform of its own, codenamed Project 92. During a company-wide meeting on Thursday, Meta chief product officer Chris Cox showed off a set UI mock-ups to the assembled employees, which were promptly leaked online.

The project’s existence was first officially confirmed in March when the company told reporters, “We’re exploring a standalone decentralized social network for sharing text updates. We believe there’s an opportunity for a separate space where creators and public figures can share timely updates about their interests.” A set of design images shared internally in May were leaked online as well.

The new platform, which Cox referred to as “our response to Twitter,” will be a standalone program, based on Instagram and integrating ActivityPub, the same networking protocol that powers Mastodon. The leaked images include a shot of the secure sign in screen; the main feed, which looks suspiciously like Twitter’s existing mobile app; and the reply screen. There’s no word yet on when the app will be available for public release.

“We’ve been hearing from creators and public figures who are interested in having a platform that is sanely run, that they believe that they can trust and rely upon for distribution,” Cox said, per a Verge report. Celebrities including Oprah and the Dalai Lama have both reportedly been attached to the project.
