I can't wait for higher-quality built-in proofreader on os x. I don't love real-time spell checkers, I'd prefer to just dump an email with no error highlighting, hit a keystroke and have it re-written proofed (with dyslexia often the only way I can find my own errors is by reading the text backwards). I built a GPT in the "built your own GPT" thinger ChatGPT has now, and I copy/paste stuff in, hit enter and it sends back a corrected version and underneath a list of the corrections it made. So far it's batting 1.000. I'm going to see if I can use this for that.
