Weaknesses	Google-only Can be slow on large corpora	Less agentic than Cursor/Claude Code Model quality varies	Not for full songs with vocals Shorter generation limits	Writing quality trails Claude Over-refusals on edge content UI is cluttered
Kai's verdict	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
