This is different from merely reading it out loud by yourself, which doesn’t give you enough distance.
What I'd really like to do is have a standard "spell/grammar/plothole/tone/etc." critique prompt and have google docs start me from the top and roll down the entire document so we work on one sentence/paragraph at a time and see if I agree with anything pointed out or suggested. Right now there's a lot of copying/pasting, contextless critiquing, but at least claude will be able to read my full document for full context.
There's also a Python package on pypi called pyttsx3, which I used to write a very simple command line program to say whatever is on my clipboard.
