Inline Studio

Inline Studio is a free, open-source desktop app for AI filmmakers who want to compose narrative video projects shot-by-shot on a free-form node canvas. Unlike typical AI video tools that handle single generations, Inline Studio treats a project as a pipeline of many shots—each with its own ComfyUI workflow—layered and wired together. Versioning is built in: every take and frame is preserved, so you can iterate without losing earlier results. The app connects to your own ComfyUI instance (local or cloud) for rendering, keeping your media and models fully under your control. On the canvas, you can assemble and edit directly using built-in nodes: the new Video Director combines rendered frames into a timeline with audio layering, while Trim Video/Audio lets you cut clips with waveform handles. An optional AI assistant (Claude via your own API key) helps plan frames and wire previews, but never edits without your approval. Targeted at intermediate to advanced ComfyUI users, Inline Studio fills the gap between single-image generators and full non-linear editors. It's ideal for short films, storyboard-to-final-cut pipelines, and complex multi-workflow projects. The community praises its frame/take model for solving the mess of version tracking in node-based workflows. Unlike commercial alternatives (e.g., Runway, Pika), Inline Studio is free, open-source, and deeply integrated with ComfyUI, but requires existing familiarity with the ecosystem.
