Every month, I see a new “lookalike” contest pop up on social media.
Timothée Chalamet, beabadoobee, etc. Some artists like bbno$ have even taken to TikTok to create his own lookalike contest.
In a sense, it feels like a “humorous” intro to cosplay.
Separately, Dress to Impress took Roblox by storm with plenty of kids and adults selecting outfits and rating them online.
So there’s the idea. A lookalike contest app.
Users (or the app) start their own competition. Perhaps there’s a prize, perhaps it’s just for fun. People submit their best lookalike pictures to it. The contest owner gets to select their favorite; or we can create a jury that selects a winner through ranked choice voting.

Who would run a contest?
I’d begin with a host who already has a community and wants to organize one lookalike event. The app shouldn’t need to manufacture a social network before anyone can use it. A contest page, a way to submit an entry, and a clear voting process would cover the first job.
How would I keep the first version small?
Entrants could submit their own photos with consent and review the contest rules before publishing. The host would choose a closing date and whether a jury or participants select the winner. I’d make prize terms and the use of uploaded images explicit rather than treating them as fine print.
What would I test?
I’d try one event and watch where the host ends up doing manual work: reviewing entries, handling duplicate votes, or contacting a winner. Abuse reports and photo removal would matter from the beginning. I wouldn’t start with automated facial similarity scoring. The fun is the community’s judgment, and the first experiment is whether the software makes a contest easier to run.
