Prompt first
Write the prompt, then adjust model, size, steps, seed, sampler, and the useful generation controls.
Image and video generation
A cleaner UI for image generation.
Run ComfyUI, open J AI Studio, and generate from a simpler page.
ComfyUI front end
Prompt first. Controls second.
Model-aware controls
Controls change with the selected model and workflow, so incompatible settings stay out of the way.
Live previews
See queue status, progress, previews, and cancel controls while ComfyUI is running the job.
Zen mode
Use a fullscreen prompt and output view when you do not need the full controls panel.
J AI Studio - FAQ
Before you run it
Answers to the practical setup questions.
> .env
COMFY_URL=http://127.0.0.1:8188
> npm run build
What is it?
A simple browser UI for ComfyUI. It is for generating and reviewing outputs, not editing node graphs.
What do I need installed?
Node.js 20 or newer, plus a working ComfyUI install. The default ComfyUI URL is http://127.0.0.1:8188.
Where do files go?
Generated media stays in your local ComfyUI output setup. Gallery metadata lives in J AI Studio's data folder.
Does video work?
Yes, if your ComfyUI setup has compatible video nodes and workflows installed.
Can I use my own workflow?
Yes. Export a ComfyUI API workflow, add the J AI Studio control mapping, then import it from Settings.
How do updates work?
Use Settings -> Update in a Git checkout. Manual update is git pull, npm install, npm run build, then restart.
Use ComfyUI without living in the graph.
Keep the node editor for setup. Use J AI Studio for the daily generation loop.
