What's the difference betwee hostted by Jina AI and hosted by jCloud? I think this title is misleading. Maybe we can just use # Cloud Hosting?

[numb3r3]

I think this page would explain the SaaS product.

[ZiniuYu]

One is hosted by Jina, right now the user can only access it but not control it.
The other is hosted on Jcloud, the user has full control of it

[numb3r3]

But this title does not tell the difference
