Kai's verdictS-tier for solo + free. The best free option, hands down.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for speed. When latency is the product, start here.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
