The grid.io was an AI version of something like squarespace. The premise was you wrote the content and uploaded the images, and it would select the best design for you.

Unfortunately, it didn't work well in practice. This was only discovered a year after tens of thousands of people signed up, when it was finally released.

Big impact for the announcement video. Small impact for the release.

I'd guess that it's related to https://thegrid.io/
