Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
