Multi-Language Watermarks for Global AI Opt-Out
Create watermarks in multiple languages to communicate AI training opt-out to a global audience. Covers English, Japanese, Chinese, Korean, and more language options.
Detailed Explanation
Multi-Language Watermarks
AI training datasets are assembled globally. A scraper in China may not parse English text, and a European scraper may not read Japanese. Multi-language watermarks ensure your opt-out message is understood everywhere.
Available Preset Texts
This tool includes preset watermark texts in multiple languages:
| Language | Text | Characters |
|---|---|---|
| English | DO NOT USE FOR AI TRAINING | 28 |
| Japanese | AI学習禁止 | 6 |
| Chinese (Simplified) | 禁止AI训练使用 | 8 |
| Korean | AI 학습 금지 | 7 |
| German | NICHT FÜR KI-TRAINING VERWENDEN | 33 |
| French | INTERDICTION D'UTILISATION POUR L'IA | 38 |
| Spanish | PROHIBIDO PARA ENTRENAMIENTO DE IA | 36 |
Strategies for Multi-Language Coverage
Strategy 1: Alternating Lines
In tiled mode, alternate between two or three languages across rows:
Row 1: DO NOT USE FOR AI TRAINING
Row 2: AI学習禁止
Row 3: DO NOT USE FOR AI TRAINING
Row 4: AI学習禁止
This doubles coverage across language barriers while keeping each row readable.
Strategy 2: Concatenated Text
Combine languages in a single watermark string:
DO NOT USE FOR AI TRAINING | AI学習禁止
This is longer but guarantees both languages appear in every tile. Use a smaller font size to compensate for the length.
Strategy 3: Primary + Symbols
Use your primary language as tiled text and add universal symbols (robot prohibition) to handle other languages. This is simpler and avoids font rendering issues.
Font Considerations
Not all fonts support CJK (Chinese/Japanese/Korean) characters. The tool uses the system's default sans-serif font, which supports CJK on most modern operating systems:
- macOS: Hiragino Sans, PingFang SC
- Windows: Yu Gothic, Microsoft YaHei
- Linux: Noto Sans CJK
If CJK characters render as boxes, the system lacks the required fonts. In this case, use the symbol-only strategy for international coverage.
Choosing Languages
Select languages based on where your images are most likely to be scraped:
- International artists: English + Japanese (covers the two largest AI art communities)
- European creators: English + local language
- Asian creators: Local language + English
- Maximum coverage: English + Japanese + symbols (covers the broadest base)
Character Length Impact
CJK languages express the same concept in far fewer characters than Latin languages. "AI学習禁止" (6 characters) conveys the same meaning as "DO NOT USE FOR AI TRAINING" (28 characters). This means CJK watermarks are more compact at the same font size, allowing tighter tiling without visual clutter.
Use Case
An international photography collective with members in 12 countries establishes a standard dual-language watermark (English + Japanese) for all publicly shared work, ensuring consistent protection across their global audience.
