Best for	Replacing Google for any question where you want a cited answer in seconds.	VS Code users who want agentic coding without changing IDEs.	Anyone already on Google, research tasks, summarizing long documents.	Game developers, podcasters needing SFX, video creators needing background music.

Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Can burn tokens fast if not watched Less polished than Cursor	Writing quality trails Claude Over-refusals on edge content UI is cluttered	Not for full songs with vocals Shorter generation limits
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. Best free agentic option in VS Code. Use with Claude for best results.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
