My first impression coming away from this is skepticism.

Anything with voice controls for routine use is a pretty tough sell. Doing this when you're not completely alone would be annoying to everyone around you.

Most of their examples seem like they could have been done with a right click drop down menu so they don't really need to "re-invent the mouse pointer".

So is this thing talking to Google's servers all the time for the AI integration? So it won't work if you're not connected to the internet? Privacy concerns are obvious; now Google wants to have an AI watching literally everything you do on your computer?

Does it cost the user anything for the LLM use? If it's free will it stay free forever? That's quite a lot to give away if they're expecting people to use it to change a single word like in one of their examples. I guess they're expecting to make the money back by gathering data about literally everything you do on your computer.

There might be a killer app for AI integration with personal computers that has yet to be invented, but this doesn't look like it.
