Powered by your own ComfyUI

Narrative-first filmmaking, frame by frame.

Inline Studio is a desktop app for filmmakers. Compose your film on a free-form node canvas and work frame by frame, while ComfyUI quietly does the generation behind each one.

The Inline Studio node canvas, composing a film frame by frame with generated takes.

A frame is not a file. It's a slot with a history of takes.

Filmmakers re-shoot. So every render you make becomes an immutable take that lives under its frame — nothing gets overwritten. Pick the one that works, and that's the one that flows on to the next shot. That versioned-take history is the thing ComfyUI doesn't give you, and it's what the whole app is built around.

Built-in assistant

An AI that works alongside you on the canvas

Connect your own Anthropic API key and ask in plain language. Claude proposes concrete changes you apply with one click — it plans frames, groups them in layers, wires up previews, and even builds a frame's ComfyUI workflow grounded in the nodes and models you actually have installed. It never edits your project behind your back, and everything it does is undoable.
