What project would you love to build but haven't started yet?

I'm curious what everyone is working toward.

Is there a project you've always wanted to build but never got around to starting?

Maybe it's:

• A URL shortener

• An AI chatbot

• A recommendation system

• A real-time chat app

• Something completely different

Share your idea and what's stopping you from starting. Maybe someone here has already solved a similar problem and can help.
