Kai's verdictA-tier. Great price/performance. Go here if ElevenLabs is too expensive.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
