ShowPapers is maintained by independent developers. Its source repositories are private today. We will link any public source release and its license here when it is available.
The Android and iPhone apps are built with open-source components, such as PaddleOCR models, ONNX Runtime, OpenCV, LiteRT-LM and the Manrope font; the iPhone app also uses PDFium. Supported phones download the Gemma 4 E2B model. Each component keeps its own license. For questions about the code or a security concern, contact us using made-up examples.
