Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for solo + free. The best free option, hands down.
