# Yolodex > Yolodex is the world's first Creative Scientist™. Custom-built machine learning models analyse your winning ads, work out which variables actually drove the result, and turn that into 50+ human-grade creative briefs and a bespoke experimentation plan for your next sprint. Yolodex, Inc. is a San Francisco-based company. The product is built by AI researchers from Meta AI, Stanford, Cambridge, and Oxford. Access is limited — Yolodex works hand-in-hand with a small number of brands at a time. ## What is a Creative Scientist? A creative strategist guesses with taste. A Creative Scientist runs the experiment. Machine learning takes every winning ad apart frame by frame — the hook, the format, the pacing, the person on screen, the music — and isolates which variable actually drove the result. That becomes the next round's test plan. The ads run, the numbers feed straight back in, and the loop closes without anyone having to work it. The models are deterministic, so the same evidence gives the same answer twice. ## How it works - Plug in your data: a mix of internal and external data sources plus your ad performance data, run through the persona engine. - Confirm where to play: the models rank every persona and angle by where the real opportunity is, and you confirm the recommendations. - Get the briefs: 50+ human-grade creative briefs in minutes instead of days, complete with inspo (images, video) and the evidence behind each one. - Run ads and learn what works: you produce the ads and put them live; Yolodex learns what works and updates its recommendations for your next sprint. ## How Yolodex compares to a creative strategist using Claude + Motion Both produce human-grade creative briefs and track competitor ads. Only Yolodex runs on custom-built machine learning models, produces 50+ briefs in minutes rather than days, surfaces personas from outside your ad account, and improves autonomously from ad results rather than needing to be taught. ## Who Yolodex is for Growth and creative teams at DTC brands running paid social, mostly on Meta, who need new winning angles faster than one person can find them.
