Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.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.
