Compare AI tools

	Cursor S	OpenRouter S	Suno S	GitHub Copilot B
Tagline	VS Code fork that made AI coding actually work.	One API, every model. Pay-as-you-go, no subscriptions.	Prompt to full song with vocals, instruments, the works.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.
Category	coding	dev platform	audio	coding
Pricing	Free + $20/mo Pro + $40/mo Business	Pay per token — model-dependent	Free + $10/mo + $30/mo	Free (limited) + $10/mo Pro + $19/mo Business
Best for	Developers. Non-developers who want to ship working code.	Developers experimenting across models. Apps that want fallback logic.	Jingles, intros, demos, sketches, personal use.	Teams with GitHub already. Devs who don't want to change IDEs.
Strengths	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Real songs with real lyrics v4 is very good Quick turnaround	Great enterprise story Works in your existing IDE Chat + autocomplete
Weaknesses	Can feel overwhelming for non-coders Expensive at scale	Slight markup over direct API Some provider features not exposed	Copyright gray zone Audio quality behind studio	Less agentic than Cursor/Claude Code Model quality varies
Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier in its category. The first AI music tool I'd actually listen to.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
