What Is Surya? Surya 是什么？
Surya is an open-source project with 21k+ GitHub stars. Accurate multilingual document OCR and line detection
The project focuses on ocr, document, multilingual use cases and is designed as a ready-to-use application—you can deploy or run it directly without writing integration code.
Source code is available at github.com/VikParuchuri/surya. Its 21k+ GitHub stars indicate strong real-world adoption across engineering teams globally.
Processing invoices across Southeast Asian markets requires Surya's 90+ language OCR precision—alternatives sacrifice accuracy for speed. Unlike Tesseract, Surya's line detection handles skewed documents without preprocessing, saving development time. Skip this if you need real-time processing on edge devices; the 21k+ GitHub stars reflect power over efficiency.
