Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier in its niche. The only one that actually gets emotion right.S-tier in the agent category. The first one I'd give to a non-technical friend.
