I built Threadline for the $100k Higgsfield App Contest I just entered Threadline into the Higgsfield App Contest — an AI launch studio for streetwear and fashion brands. Upload one product mockup, and it turns into a full launch pack: styled product photos, a lookbook video, a UGC-style clip, and ready-to-post captions.

The whole thing was built by Claude, through Higgsfield's own MCP server — direct git access to the app's repo, real deploys, iterating live against the actual running app instead of a local mockup. No hand-written scaffolding.

A few things I focused on: mixing different AI models per asset (or locking one model so the same person shows up across every photo and video), editing any generated photo with a prompt, and a full history so nothing you generate is ever lost. Full technical breakdown, including what I ran into building on Higgsfield's own design system: https://contra.com/p/mP2FqcZc-ai-powered-app-threadline-for-higgsfield-supercomputer

Try it live: threadline.higgsfield.app — or on the Higgsfield platform itself: https://higgsfield.ai/supercomputer/apps/0eabe215-ee8b-4c39-9457-b3ae3cca9004/view

If you're in this community and already build with Higgsfield — come test it and tell me what's broken and what could be better. This is v1, and I want to keep pushing it until it's an actual tool people reach for, not just a contest demo.
