Kai's verdictA-tier. HeyGen wins for creators, Synthesia wins for enterprise.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
