Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
