TaglinePrompt to full song with vocals, instruments, the works.Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript.Build a full app from a prompt. Stripe-ready.The pro's AI video tool. Gen-4 is the current bar.

PricingFree + $10/mo + $30/moToken-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens.Free + $25-$100/moFree + $15-$95/mo
Best forJingles, intros, demos, sketches, personal use.Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch.Non-devs + solopreneurs shipping MVPs.Marketing video, pitch decks, b-roll, creative shorts.
Strengths
  • Real songs with real lyrics
  • v4 is very good
  • Quick turnaround
  • Same runtime as the Cursor IDE — no reinventing sandboxing, context management, or model routing
  • Three execution modes: local machine, Cursor cloud VMs (isolated per-agent), or self-hosted workers for air-gapped teams
  • Cloud agents are durable — keep running even if your laptop sleeps or connection drops, and can open PRs automatically on finish
  • Full harness included: codebase indexing, MCP servers, skills, hooks, and multi-agent delegation via subagents
  • Visible in Cursor's Agents Window — programmatic runs can be inspected or taken over manually in the IDE
  • Generates full apps + DB + auth
  • Good for non-developers
  • Ships faster than hand-coding
  • Most mature video workflow
  • Character consistency via Act-One
  • Gen-4 quality is production-grade
Weaknesses
  • Copyright gray zone
  • Audio quality behind studio
  • TypeScript-only SDK — no official Python or other language bindings at launch
  • Public beta status means API surface and pricing can shift without much notice (Cursor has a track record of surprise pricing changes)
  • Cloud VM costs layer on top of subscription credits, making cost estimation non-trivial at scale
  • Complexity ceiling
  • Can generate brittle code
  • Expensive at scale
  • Still needs post-editing
Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.)A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier. Market leader with reason. Start here for serious video.
