Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for data teams. S-tier if you already live in SQL + Python.
