Current models can kind of do this, e.g. you could give some text to GPT-3 and ask it to do this. Not sure what the limit on the input length before results degraded would be. But yep, would be nice to see this out there in a nice interface and working well.

Semantic search could be used for this, e.g. finding blocks of text similar to what you've already written

But yep, this stuff isn't all nicely packaged in one place
