Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
