Do I still need ComfyUI with Musetta?

Yes, or a rented GPU, or API providers. The studio is the workspace; ComfyUI is one of the engines it drives.

Can I use my existing workflows?

Yes. Import a ComfyUI workflow and the studio reads its inputs and gives each one a control, so you can run it without opening the graph.

Does the studio change my ComfyUI install?

Only when a workflow needs a missing node pack: it installs it, restarts ComfyUI and tells you what changed.

Musetta vs plain ComfyUI

Updated September 26, 2026

The short answer

It is not either-or: Musetta runs on ComfyUI. ComfyUI gives you total control through a node graph; the studio adds what an AI influencer workflow needs around it: one character kept consistent across every tool, a model library matched to Civitai, a real control panel for each workflow, every output’s recipe, rented GPUs and a copilot. Keep ComfyUI for building graphs; use the studio for running a character day after day.

Choose Musetta if

You post as one or more characters and need them identical every time.
You would rather press Generate than rewire a graph for each shot.

You are experimenting, not producing a feed on a schedule.
Your budget is zero.
