Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
