PlayTranslate OCR models
On-device OCR model packs for the PlayTranslate Android app, converted to MNN format for mobile inference. Each subdirectory is one downloadable pack referenced by the app's model catalog; the app fetches the individual files directly and verifies a pinned SHA-256 per file.

† Hosted ahead of in-app language wiring (support coming soon). The first four packs are live in the app; these four are downloadable and integrity-pinned but not yet mapped to a selectable source language.
The shared PaddleOCR PP-OCRv5 DBNet text detector is bundled inside the app APK (not hosted here) and is paired with whichever recognizer pack above the source language selects.
