| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | 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. |
