Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier in its niche. The only one that actually gets emotion right.
