+# SHARP · 3D from a Single Photo
+Upload any photo and get a **3D Gaussian Splat (.ply)** in seconds.  
+Powered by Apple's [SHARP](https://github.com/apple/ml-sharp) monocular view synthesis model.
+
+**How to use:**
+1. Upload or drag & drop an image
+2. Click **Generate 3D Splat**
+3. Download the `.ply` file
+4. View it at [SuperSplat](https://playcanvas.com/supersplat/editor) ← open this in a new tab and drag your file in!
+
+> ⚠️ Running on CPU — first run downloads the 2.6GB model and may take 5–10 min. Subsequent runs are faster.
