Best for	Developers who want Cursor-like power for less money.	Developers. Non-developers who want to ship working code.	People who want to hand off tasks entirely — trip planning, research, spreadsheet building.	Game developers, podcasters needing SFX, video creators needing background music.
Strengths	Cheaper than Cursor Cascade agent for multi-file tasks Solid free tier	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	General-purpose agent — research, book, build, analyze Parallel task execution Web browsing + file creation + coding	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity
Weaknesses	Smaller community Model selection more limited	Can feel overwhelming for non-coders Expensive at scale	Still hit-or-miss on complex multi-hour tasks Can burn credits fast	Not for full songs with vocals Shorter generation limits
Kai's verdict	A-tier. Close second to Cursor. If $5/mo matters, start here.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier in the agent category. The first one I'd give to a non-technical friend.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
