The one tangible usecase is perhaps booking things. But, personally, I don't mind paying 5-10% extra by going to a local store and speaking to a real person. Or perhaps intentionally buying ecological. Or whatever. What is life if you have a robot optimize everything you do? What is left?
It's a calendar, reminder, notebook, fridge scanner, and a webscraper
I think the interesting idea here is that overtime this will grow to more applications. None require integration or effort to work you only need plug the infrastructure and tooling.
This to me is what will eventually wipe out most agentic startups. The enterprise version of this little thing is just a bot and a set of documents of what it should do and a few tools. Why pay and setup a new system when I can just automate what I already have?
