Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
