All in on AI, but what of the mobile?

I like the quickly accessible AI that Raycast has and I would almost upgrade to the advanced models, but it feels weird to pay for these models in Raycast and then separately for OpenAI to get to use GhatGPT in mobile.

Perhaps somebody here has solved this question for themselves already - is there a provider like Raycast that has AI (perhaps even multiple models) in a Mobile app and is trustworthy? I wouldn't trust any random AI app from App Store and there are too many to go over them one by one myself.
