| Kai's verdict | S-tier in its category. The first AI music tool I'd actually listen to. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time. | S-tier for academic research. Nothing else comes close for systematic reviews. |
