Kai's verdictB-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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
