Kai's verdict	A-tier. HeyGen wins for creators, Synthesia wins for enterprise.	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.	B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
