Pricing	Free + $15-$95/mo	Free (limited) + $10/mo Pro + $19/mo Business	Free + $12/mo Pro + enterprise	Free + $20/mo Pro + $40/mo Business
Best for	Marketing video, pitch decks, b-roll, creative shorts.	Teams with GitHub already. Devs who don't want to change IDEs.	Game developers, podcasters needing SFX, video creators needing background music.	Developers. Non-developers who want to ship working code.
Strengths	Most mature video workflow Character consistency via Act-One Gen-4 quality is production-grade	Great enterprise story Works in your existing IDE Chat + autocomplete	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick
Weaknesses	Expensive at scale Still needs post-editing	Less agentic than Cursor/Claude Code Model quality varies	Not for full songs with vocals Shorter generation limits	Can feel overwhelming for non-coders Expensive at scale
Kai's verdict	S-tier. Market leader with reason. Start here for serious video.	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.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
