Kai's verdictB-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 infrastructure. The one platform every AI dev eventually uses.S-tier for model-shopping. I use this for every prototype before committing.
