Is my prompt or image sent to a server?
No. The model runs inside your browser through WebGPU or WebAssembly. Prompts, seeds and the rendered pixels never leave your device. The only network traffic is the one-time model download from huggingface.co.
Why does the tool download something the first time?
Rendering needs the model weights on your machine. They are fetched once in chunks, stored in your browser's cache, and reused on later visits. An interrupted download resumes where it stopped.
How big is the download and where is it stored?
Draft is about 0.9 GB and Standard about 2.2 GB. The files live in your browser's storage for this site and count toward its quota. The model panel shows what is on your device and can delete it.
Does it work offline after the download?
Yes. Once a model is cached, generating an image needs no network at all. You still need to reach this page to open the tool.
Why is it slower on my laptop?
Speed depends on your GPU. Draft renders a 512-pixel image in well under a second on a recent Apple or discrete GPU and in a few seconds on the CPU path. Browsers without WebGPU, and Safari, use the CPU path.
Can I use the images commercially?
That depends on the license of the model you pick, shown in the model panel: Draft uses SDXS-512-DreamShaper under the CreativeML OpenRAIL++-M license, Standard uses LCM Dreamshaper v7 under the MIT license. The tool itself adds no restrictions and keeps no copy.
Are the images filtered?
No. Nothing is classified or blocked; the model runs unfiltered on your own device, and what it renders is your responsibility under the model's license.
Why do tall or wide images sometimes repeat the subject?
Draft renders in a single step and was trained on square images, so it only offers ratios that were verified to stay coherent. Standard takes more steps and handles portrait and landscape frames better.
Will the same seed give the same image on another computer?
On the same device and browser, yes. A different GPU or browser can round the maths differently, so the image may differ slightly or, with a one-step model, noticeably.
How do I delete the model and free the space?
Open the model panel and choose Delete from device. Clearing this site's data in your browser settings removes it as well, together with your local library.
