For me. its better to use other AI platforms since meta AI is connected to my real account.
The conversation is not end to end encrypted. so there's a huge possibility that our conversation will be reviewed and they will know all about my information.
I would rather use other AI platform and use a dummy account. even if its not end to end encrypted and can be reviewed by others. they won't exactly know who the person chat with that conversation.
In short. more privacy. better
