Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.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 coding. If you write code of any kind, this pays back the $20 in a day.
