Feature Request: Use ML(?) to determine the closest match

I use Google Fonts for nearly everything since it is reliable and there is an awesome array of fonts to choose from!

One thing that I would absolutely *love* is if Google offered the closest matching font when it doesn't doesn't offer a font that is being searched for and instead shows an external font foundry where you could get the font.

Show the link to the external foundry in case a very specific font is needed. A "similar font" section would also be great though!
