Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
