AI Comments and Change Proposals on the whole Document

I would love to integrate the AI with the comment feature. Have a prompt go over the entire text to find instances of something, flag them, and maybe even generate a card or two you can approve out of the comment feature. Like approving a change in a google doc. My dream is to tell the AI someting like "fix my spelling" and it goes over the entire document and returns with a list of instances, I can look at individually. Ideally, the AI can interact with them. So I can say "Lets take on the comment about X" and it pulls it up. Then I can fine tune the change and approve it to be inserted.

Make it a bit like the canvas feature of other AIs but with finer control :)
