Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier if you already pay Gemini. B-tier standalone.
