bitGen Studio for ComfyUI users
ComfyUI does the rendering. bitGen Studio gives it a studio: one simple window for your models and workflows, with a timeline, an AI image editor and music - all on your own computer.
ComfyUI underneath, a studio on top
Every picture, clip and song bitGen makes is a ComfyUI workflow run on your graphics card. Already have ComfyUI? Point bitGen at its folder in Settings ▸ ComfyUI. New to it? The installer sets up ComfyUI, the node packs and the models that suit your graphics card for you.
Bring your own workflows
Import any workflow you built in ComfyUI. bitGen checks it, draws the graph, test-runs it and keeps it - then it runs from the Generate button with just the controls it needs: prompt, seed, steps, size. See how.
Your models, found and kept in order
The Model manager reads every model in ComfyUI's folders and extra_model_paths.yaml - a card each, its type read from the file. Before a render, bitGen checks the files are there and offers to download any that are missing. Add a model.
Video, images and music in one place
- Video: MiniMax H3, LTX 2.5 / 2.3 and Wan 2.1 / 2.2 - text to video, reference pictures to video, first and last frames, long clips in parts.
- Images: FLUX, Qwen Image, SDXL and more, with an AI image editor - edit a part of a picture, fill a selection, extend it.
- Music, voices and sound effects - then cut it all together on the timeline.
Every feature is on the Features page.
Local AI - no cloud, no account
It all runs on your computer: ComfyUI, the local language model that improves your prompts, speech recognition. Your files stay yours. When your own graphics card is not enough, bitGen can use ComfyUI on another computer or a rented GPU instead.
