Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier for data teams. S-tier if you already live in SQL + Python.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
