2 plan / billing-period records, all listed; — means that period is not recorded.
The official FAQ ("How much does it cost?") explicitly states that Hama is free, and users only need to log in to download high-resolution images in Hama PRO. Guests can export unlimited 720px unwatermarked images without login, and logging in unlocks Hama PRO (HD) for free.

Tested result & sample
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.

- Network-observed server wait

Network wait includes round trips, queuing and polling error, not pure inference time. Local timings depend on the device; repetition counts are not standardized in legacy records.

Experience, rules & trust
- Disclosure
- Top banner promotes 'Try hama PRO (HD)', though the exact 720px cap is only evident upon inspecting the downloaded file
- Interaction
- Completes the full workflow without registration, but embeds Google AdSense floating overlays and shopping anchor banners (see bottom-right of 02_workspace.png) that can intercept upload clicks.

Honesty & reputation · 73/100 · 30%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Pricing transparency | 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). | Evidence A → |
| Interaction restraint | 21 / 30 | Completes the full workflow without registration, but embeds Google AdSense floating overlays and shopping anchor banners (see bottom-right of 02_workspace.png) that can intercept upload clicks. | Evidence A → |
| Background & reputation | 16 / 20 | Established web-based AI object eraser (Hama.app) launched in 2021, widely used for quick watermark and object removal. | Evidence B → |
| Engineering & privacy | 12 / 15 | Resizes the canvas to 720×720 on the client before submitting to /api/hama-inpainting (8.78s cloud inference), reducing upload size at the cost of 2K high-frequency detail. | Evidence A → |
Capability · 74.5/100 · 70%
| Criterion | Score | Rationale | Basis |
|---|---|---|---|
| Task quality | 51.5 / 65 | Masked GT Reconstruction (22.5/30: structural PSNR=15.12dB · SSIM=0.4002) · Unmasked Fidelity (16.5/20: unmasked_psnr=25.16dB, limited by 720px downscaling) · Texture Continuity (12.5/15: coherent bookshelf and wood-grain blending) | Evidence B → |
| Deliverable specifications | 11 / 20 | Exports a free 720×720 unwatermarked JPEG without login, reducing linear resolution by 64.8% from 2048×2048 (11/20) | Evidence B → |
| Processing speed | 12 / 15 | CDP measured 8.78s pure cloud inference across /api/hama-inpainting for all 3 zones simultaneously | Evidence B → |
