Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for open-source model APIs. The default in this space.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
