Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
