Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
