Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
