Google Drive works well if I want cloud-file-storage + lexical-search.

I studied the box.com website and found a product which captures my interest:

https://www.box.com/ai

I tried to signup for a box.com account but it failed at the final step.

The mechanism which is supposed to send me verification-e-mail is acting broken.

Unfortunately, box.com has my credit card now and I worry they will charge me for the privilege of having a broken account on box.com.

I studied MS-One-Drive and I see no semantic-search there.

I compared Google-drive lexical-search to MS-One-Drive and Google works better.

I studied gradient.ai and found their semantic search to be really good but their folder UI is clumsy.

I studied vectara.com and found their folder UI to be better than gradient.ai but gradient's semantic search is better.

What's a good service which offers cloud-file-storage + semantic-search?
