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.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.
