| Kai's verdict | S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work. | S-tier infrastructure. The one platform every AI dev eventually uses. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | B-tier. Still early. Manus is more flexible for less money. |
