The Worldwide Show and Tell Challenge presented by Mux announced its winners, recognizing standout developer projects. The overall winner was BOLD, a video search platform by Marcel Fahle that uses AI to find specific moments in video libraries. It integrates with transcription providers and Mux for encoding.

Fragments, built by Neilblaze and Achai Bajpai, won the Best Use of Mux category. This 'visual second brain' for creators leverages Mux's platform for direct uploads, AI transcription, and dynamic thumbnails. Both projects solve practical problems for developers working with video content at scale.

The contest highlights how developers are building on video infrastructure platforms like Mux to create specialized tools. Winners receive $1,500, DEV++ memberships, and exclusive badges. All participants earn a completion badge, reinforcing the community's focus on sharing and showcasing practical applications.
