Kai's verdict	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
