Kai's verdictS-tier for solo + free. The best free option, hands down.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
