Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for designers. The only one that takes vectors seriously.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
