AP tried the feature on a Pixel 2 XL running the Android 8.1 developer preview, but we got similar (not exact) responses using 8.0. This doesn't work on other Android phones, though. And help for other issues is limited. We asked why our phone was slowing down, and it pointed us to a "more info" link.

We've asked Google if it can comment on the feature. However, it's reasonable to believe that this AI support could become more robust over time. If Google can point you to Assistant for help with numerous issues, it potentially lightens the load for flesh-and-blood support reps by limiting their involvement to trickier problems.
