| Kai's verdict | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | S-tier for solo + free. The best free option, hands down. |
