I wondered if it could help clean up audio‑transcription text, so I gave it a try. The “Fix Writing” option didn’t work as I’d hoped—it just seemed to flag grammatical mistakes. I was about to give up, when I realized that even on the free plan you can add custom prompts. I added one that said, “Remove unnecessary sound effects and tidy up the Japanese,” and it worked exactly as I wanted. It looks like there are plenty of other ways I can apply it. I’ve only been using it for about an hour, but I’m hoping it will improve my workflow as dramatically as CleanShot X did.
