I'm new to the startup world. What's the main feature of your app? Are you solving any particular problem with it?

First timer here, so appreciate all the tips. Would you say it's better to exchange currency before you go, or just withdraw there? Oh, and any specific apps that helped you navigate around?

Isn't there a chatbot or something that's powered by GPT-5? Heard about it somewhere. If that's the case, what's stopping it from taking over customer service jobs? Or maybe that's already happening and we don't know it lol.
