BioniX is the only wallpaper changer on the planet with built-in AI Border Fill. When your wallpaper doesn’t match your monitor’s aspect ratio, BioniX uses AI to extend the image naturally — generating new pixels that blend seamlessly with the original.
You have a beautiful portrait shot, a square Instagram photo, or a 4:3 family picture. Your monitor is 16:9. Until now, you had three ugly choices — and they all ruin the image.
Distorts faces, landscapes, and everything in between. Looks unprofessional.
Cuts off the top of someone’s head, or the most important part of the scene.
Lazy, dated, and a waste of expensive screen real estate.
BioniX detects the mismatch and asks an AI model to paint the missing area. The original image stays untouched. The AI invents only what wasn’t there — the sky next to the mountain, the wall next to the portrait, the floor below the subject. The result fills your monitor edge-to-edge.
Pick a provider once. After that, every mismatched wallpaper gets the AI treatment automatically.
BioniX measures the wallpaper’s aspect ratio and compares it to each monitor in your setup.
It calculates how many pixels need to be generated on the left, right, top, or bottom for an exact fit.
The padded image is sent to your chosen AI provider (local or cloud). The AI paints the missing area in seconds.
The result is cached locally per monitor resolution. Switch back to the same wallpaper and it appears instantly.
Seven providers supported. Free on your own GPU, or pennies per image in the cloud. Your call.
| Provider | Type | Cost per image | Speed | Hardware |
|---|---|---|---|---|
| ComfyUI Free | Local | Free | 30 s – 4 min | NVIDIA GPU, 6+ GB VRAM |
| SD WebUI / Forge Free | Local | Free | 30 s – 4 min | NVIDIA GPU, 6+ GB VRAM |
| Runware | Cloud | $0.0006 | 5 – 10 s | Any PC |
| Stability AI | Cloud | ~$0.01 | 5 – 15 s | Any PC |
| fal.ai | Cloud | $0.01 – $0.08 | 5 – 15 s | Any PC |
| Replicate (FLUX.2) | Cloud | $0.03 – $0.055 | 10 – 30 s | Any PC |
| OpenAI (GPT Image) | Cloud | $0.04 – $0.12 | 5 – 10 s | Any PC |
Cloud costs are charged by the provider directly — not by us. You pay nothing extra to SciVance Technologies for AI features. Pick the provider that fits your wallet.
The details that separate a thoughtful integration from a slapped-on AI gimmick.
Choose a local provider and your images never leave your computer. No telemetry, no upload, no SciVance servers in the loop.
Each wallpaper is processed once per monitor resolution and cached on disk. Switching back is instant. Cloud costs stay under control.
A 1920×1080 monitor and a 2560×1440 monitor each get their own optimized version. Spanned across monitors, BioniX generates one wide image.
Pre-process your entire playlist in the background, or generate each wallpaper the moment it appears. Batch mode shows estimated cloud cost up front.
AI provider offline? Server hiccup? BioniX silently reverts to its traditional fit modes (stretch, crop, smart-color fill). No interruption to your workflow.
BioniX ships with a built-in ComfyUI outpainting workflow that uses only stock nodes. Plug in ComfyUI, drop an inpainting model in the folder, you’re done.
Generation runs on the AI provider — not on BioniX. BioniX itself stays light. On laptops, you can disable AI on battery to save power.
Advanced ComfyUI users can load a custom workflow exported in API format. Tune the prompt, model, sampler, anything. BioniX won’t fight you.
Not for the BioniX side. AI Border Fill is built into the app at no extra charge. If you pick a local provider (ComfyUI or SD WebUI/Forge), you pay nothing at all — the AI runs on your own GPU. If you pick a cloud provider, you pay the provider directly: typically a fraction of a cent per image with Runware, up to about $0.12 with OpenAI’s top model.
Only for local providers. ComfyUI and SD WebUI/Forge want an NVIDIA card with at least 6 GB of VRAM. If you don’t have one, just point BioniX at a cloud provider and it’ll work on any laptop — even integrated graphics.
With local providers: no. Everything stays on your machine. With cloud providers: yes, the image is sent to the provider’s servers for processing. BioniX shows a one-time privacy notice the first time you select a cloud provider, so you can opt out before anything leaves your computer.
Cloud providers: 5 to 30 seconds per image, on average. Local providers depend on your GPU — from about 30 seconds on an RTX 4090 to 3–4 minutes on an RTX 3060. Results are cached, so you only wait once per wallpaper per resolution.
You’ll see the result before it’s saved. If it’s off, just hit Regenerate for a different output, or fall back to a traditional fit mode for that wallpaper. The cache is editable too — delete an entry to force a re-render.
Yes. Most AI models cap out at 1024×1024 or 1536×1536. BioniX generates at the model’s maximum, then high-quality Lanczos-upscales to your actual monitor resolution. The full-resolution version is what gets cached.
Generation runs in the AI provider, not in BioniX. So if you’re on a cloud provider, BioniX uses essentially no extra power — it’s a network request. If you’re on a local provider, your GPU does the work, which can be heavy on battery. There’s a setting to disable AI on battery automatically.
Because the “stretch / crop / letterbox” choice has been the same for 30 years and all three answers are bad. AI finally made a fourth option possible, and nobody else had shipped it. BioniX has been quietly innovating in this space since 2000, and this felt like the natural next step.
Download BioniX, point it at a local AI provider or your favorite cloud service, and watch every mismatched wallpaper fit your screen perfectly. 15-day free trial — no credit card required.
