Why I built Cobblehop

Ahmad Haji, founder

I'm Ahmad Haji, a student. Whenever I needed to get somewhere by train or bus, I just asked AI instead of digging through maps and schedules. It saved me hours, and every trip took only a few taps.

On a trip to Boston and Salem, I saw how hard it still is for everyone else: visitors who don't read English, people juggling three apps, and us, riding right past our stop.

I realized this could help a lot of people, so I built Cobblehop: say where you're going, get one clear route, and get a buzz before your stop. This is just the start, and I'm expanding it from here.
