Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier in its niche. The only one that actually gets emotion right.
