Kai's verdictB-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.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
