Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for model-shopping. I use this for every prototype before committing.
