Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for creators training custom looks. B-tier for general use.S-tier for model-shopping. I use this for every prototype before committing.
