| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | 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. |
