Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Close second to Cursor. If $5/mo matters, start here.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier in its niche. The only one that actually gets emotion right.
