Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
