Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.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 model-shopping. I use this for every prototype before committing.
