Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
