Other features: Side-by-side comparison of any two cars AI quiz that recommends cars based on your budget, lifestyle, and commute Specs, safety ratings, and pros/cons for every major model Resale value estimator and loan

19yr old friend and I made an ai haircut tool! Hey all, my friend and I dropped a haircut visualization tool a few weeks ago to cut down onmiscommunication in the barbershop by generating a photo of you with the cut you want from three angles. We have officially launched now with around 25 users and are trying to get more to try it out! The first generation is free so we’d love as many as possible to try it out if you get a minute! Good luck to all your side projects! subm
