Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for model-shopping. I use this for every prototype before committing.
