Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier in its niche. The only one that actually gets emotion right.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
