| 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. The most interesting spreadsheet in years. Great for ops dashboards. | A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone. |
