Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier. Category leader. Nothing else is close yet.S-tier infrastructure. The one platform every AI dev eventually uses.
