| Kai's verdict | S-tier. If you're on Vercel/shadcn, this is cheating. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. |
