Kai's verdictA-tier for designer-led sites. S-tier if animations matter.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
