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.S-tier for model-shopping. I use this for every prototype before committing.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
