Frequently asked questions
Will the extension look real?
It mirrors and blends edge content with feathering — convincing for textures/backgrounds, less so for complex structure.
Is it free to use?
Yes — AI Outpaint is completely free. No account, no watermark, no credits, and no usage limits.
Do my files or prompts ever leave my device?
No. Everything runs locally in your browser via WebAssembly/WebGPU — there is no server that receives your files, prompts, or results.
Which browser and hardware do I need?
A modern browser. Chrome and Edge get WebGPU acceleration for the fastest results; Firefox and Safari run via WebAssembly. This tool downloads nothing and runs on any device.
Can I use the results commercially?
Yes. You own everything you create — NSS makes no claim to the images, videos, or text you process or export.
Does it work on mobile?
Yes — it runs on phones and tablets too, since there is no model download.
Where can I see a step-by-step guide?
Yes — there is a full walkthrough at /how-it-works/ai-outpaint.
