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.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
