| Hallucination Control / 5* | 4.26 | 3.44 |
Top-10 Quality and Hallucination Control are diagnostic scores already included in the main metadata benchmark scoring. Noamax led every main metadata category. The largest gaps appeared in accuracy, coverage, and keyword ordering.

Metadata Quality
Metadata quality created the biggest separation between the two AI keywording tools.
Noamax AI scored 59.98 / 65, while PhotoTag scored 51.02 / 65. PhotoTag often recognized the main subject correctly, but its outputs were more likely to include weaker or speculative supporting concepts. Noamax was more consistent at keeping the strongest subject terms and useful commercial concepts near the top.
| Metric | Noamax AI | PhotoTag |
|---|---|---|
| Accuracy | 22.84 / 25 | 19.99 / 25 |
| Coverage | 14.14 / 15 | 11.71 / 15 |
| Keyword Ordering | 13.28 / 15 | 10.83 / 15 |
| Title & Description | 9.72 / 10 | 8.49 / 10 |
| Top-10 Quality | 16.30 / 18 | 13.63 / 18 |
| Hallucination Control | 4.26 / 5 | 3.44 / 5 |
| Image Wins | 10 / 10 | 0 / 10 |
The difference was also visible in Top-10 Quality: Noamax AI: 16.30 / 18 vs PhotoTag: 13.63 / 18.
For stock keywording, that matters because the strongest concepts need to appear early rather than being buried inside a long list.
Workflow & Features
PhotoTag exposes more controls for custom context, keyword limits, languages, title and description length, regeneration, keyword reordering, and other output settings. That helped it score 4.3 / 5 for Editing & Customization, compared with 3.7 / 5 for Noamax.
📌 But in practice, more controls did not always mean a better workflow. Many of these settings need to be configured before processing, which can make the first setup slower and less intuitive. A user may spend several minutes deciding what to change before generating anything.
Noamax takes the opposite approach. Most of the stock-specific logic runs in the background, so the workflow is closer to upload → start processing → review the result. In our testing, that made the day-to-day process faster and easier to understand.
📌 PhotoTag’s free workflow also placed more restrictions around copying and exporting results, which made the complete review process less convenient.
iStock & Getty Workflow
| Feature | Noamax AI | PhotoTag |
|---|---|---|
| Dedicated iStock & Getty workflow | ✓ | — |
| Controlled Vocabulary matching | Automatic | — |
| Keyword disambiguation | Automatic | — |
| Getty-ready keywords | ✓ | — |
| iStock & Getty CSV export | ✓ | ✓ |
| Extra credits for Getty processing | No | — |
Noamax AI has a dedicated iStock & Getty workflow. Controlled-vocabulary matching and keyword disambiguation happen automatically during processing, with no extra credit cost.
PhotoTag can export metadata for iStock & Getty, but it does not provide dedicated Getty controlled-vocabulary matching or automatic keyword disambiguation. Contributors still need to handle that part of the workflow separately.
