Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
