Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier in its category. The first AI music tool I'd actually listen to.S-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.
