| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier in its niche. The only one that actually gets emotion right. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. |
