Kai's verdictA-tier for designer-led sites. S-tier if animations matter.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for model-shopping. I use this for every prototype before committing.
