Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier for speed. When latency is the product, start here.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
