Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for designers. The only one that takes vectors seriously.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
