| Kai's verdict | S-tier for solo + free. The best free option, hands down. | B-tier. Still early. Manus is more flexible for less money. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
