Inbox AI - Anyone Using This?

I note that an upcoming giveaway this month is for Inbox AI. I’ve looked at this and find it intriguing, but not enough to pay $44.99 for it.

Is anyone using this? And if so what do you think about it?

Is it worth the money? More of a gimmick than a useful tool? Somewhere in between?

Thanks.

I’d be curious about this as well. It was requested by a couple people, so I contacted the dev and they were happy to be added to the giveaway list, but I’ve never used it myself.
