| Measured fixture results | Not verified | Not verified |
| Fixture findings | Automatically detected and removed the three signs; free export was limited to 1280px. | Supports marking multiple areas; reconstruction looked natural, but free output was 720px and the page had ads. |
| Original historical observation | DeWatermark.ai's AI Remove 3.0 automatically detected and erased all three occlusion boards on anchor_inpaint_v1 without any manual brushing (inpaint_psnr_db = 14.01 dB), while leaving the normal cafe OPEN sign intact; its main limitation is the 1280×1280 free export cap. | 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 | Users who want zero-effort automatic blind watermark/sign removal and accept 1280px watermark-free exports | Quick social media or small web graphics where 720px unwatermarked output without login is sufficient |
| Result & output evidence | No native output obtained; the preview does not establish final export quality. | |

| Pricing transparency | 27 / 35 Anonymous guests can upload the 2048×2048 master and freely export a 1280×1280 unwatermarked PNG; the workspace clearly displays 'Download Preview 1280 x 1280' alongside 'HD Download PRO Full 2048 x 2048' (02_workspace.png, 03_download.png). | 24 / 35 Allows guests to upload, brush, and click Finish -> Download for an unwatermarked image without login (01_landing.png, 03_download.png), but downscales the 2048×2048 original to a 720×720 JPEG on the free tier (HD requires Hama PRO). |
