How AI Photo Translation Works
Two AI steps run in series. OCR converts pixels to characters, handling printed text, handwriting, stylized fonts, and text at angles. Then neural machine translation converts the extracted text to your language while preserving structure (a translated menu still looks like a menu).
OCR Accuracy by Source
Photo translation accuracy depends mostly on the source surface and lighting.
| Source | OCR accuracy | Tip |
|---|---|---|
| Printed menu / book | 95-99% | One section at a time |
| Street sign (clear) | 92-98% | Straight-on, no glare |
| Handwritten chalkboard | 70-85% | Get close, square up |
| Stylized restaurant logo | 60-80% | Multiple shots help |
| Backlit screen | 60-80% | Reduce reflection |
| Faded receipt | 70-85% | Increase brightness |
Photography Tips
Shoot text straight on, well lit, in focus. Flatten curled menu pages. Avoid shadows. Photograph one section at a time for long documents. For handwritten text, capture the full line without cutting off edge words.
Language-Specific Notes
Japanese mixes kanji, hiragana, katakana. Chinese has Simplified (mainland) and Traditional (Taiwan, Hong Kong). Korean Hangul is the easiest for OCR. Arabic and Hebrew read right-to-left. Thai has no spaces between words. Modern AI handles all of these.
Best Travel Use Cases
Menus are the highest-impact use. Street signs for navigation. Medicine and ingredient labels for allergies. Museum plaques. Supermarket products. Receipts and bills to verify charges. All in 2-3 seconds per snap.
