Boxy is expanding. Initially, it aimed to assist with moving to a new place. However, as I use it more to organize, I envision additional features to help users manage storage overall. "Where did I store my 2024 invoices?" Foundation models will be crucial for this.

I use a bullet journal daily but struggled with managing digital links.
Bookmark folders? Overwhelming.
Long URLs? Impossible to remember.
Complex apps? Not for me.
So, I built something different. Something... numbered 🔢
Stay tuned.
