Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier if you already pay Gemini. B-tier standalone.
