When they first came through HN, there was an option for a one-off request conducted by text with a feee attached to it. It may even have been the only option, I'm not sure. I don't see it listed anymore.

I get the sense that they wanted to be a contract personal assistant and did the one-off thing to expose people to the service. Certainly it was a bit awkward since it required spending a bunch of time getting them set up with your info.
