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. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
