# PlayTranslate OCR models
|
| 7 |
+
|
| 8 |
+
On-device OCR model packs for the **PlayTranslate** Android app, converted to
|
| 9 |
+
[MNN](https://github.com/alibaba/MNN) format for mobile inference. Each
|
| 10 |
+
subdirectory is one downloadable pack referenced by the app's model catalog; the
|
| 11 |
+
app fetches the individual files directly and verifies a pinned SHA-256 per file.
