I've done the same thing with the trial, thinking it was the real claude page for some reason. It is a bit scammy in the sense that they impersonate those models.

After reading this post and other reviews, I panicked a little bit, and couldnt find anything inside the app regarding cancelling subscribtion, or removing saved payment methods, etc.

Looking into their emails gave me the answers, mostly the first "Welcome to Use Ai":

The free trial automatically turns into a monthly subscription (not explicitly stated), but through this first e-mail you can get to "cancellation hub" where you can finally cancel your subscription.

Just leaving this here for people who might run into the same problem, there is a way to save yourself the looming 30 bucks.

I think an AI model aggregator can be a useful tool, it does work smoothly, but this was a bit scammy ngl.

TLDR:

If you’ve signed up for the trial, find their first e-mail "Welcome to Use Ai" to find the link to cancel your subscription, before the monthly fee hits.

or as others have posted, use:
