| Measured fixture results | Not verified | Not verified |
| Fixture findings | Processes locally with full-size export; smooth areas worked better than complex bookshelf texture. | Supports marking multiple areas; reconstruction looked natural, but free output was 720px and the page had ads. |
| Original historical observation | Inpaint-web runs the MIGAN inpainting model locally in the browser via ONNX Runtime Web, erasing all 3 signs directly on the 2048×2048 image and exporting a full-size PNG without uploading a single byte to any server. Smooth wood surfaces restore cleanly, while complex bookshelves show lightweight client-model texture patterns. | Hama.app lets users brush all 3 signs at once and submit a single /api/hama-inpainting job (8.78s), blending bookshelf and wood-grain backgrounds naturally; its main limitations are the 720×720 free resolution cap and third-party Google AdSense overlays. |
| Suitable uses · historical assessment | Privacy-conscious users who require 100% local in-browser processing (zero cloud upload) and unlimited free 2048px+ unwatermarked exports | Quick social media or small web graphics where 720px unwatermarked output without login is sufficient |
