Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Niche but beloved. If you've outgrown Notion, try this.
