Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
