Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
