Yeah, I was pretty surprised at how they announced it. I would suspect they are working on the "try before you buy" angle. If they are targeting older people who are used to asking family for help, but don't want to always do that, this would be a good replacement.

Aira hires and trains the agents that help you, whereas apps like BeMyEyes are just random volunteers. Also I believe the agents sign confidentiality agreements so they could help with stuff that you might not be comfortable with a volunteer doing.

That's correct, you do get a 7 day free trial. But you also get free 5 minute calls after that.
