Surya vs Tungsten OmniPage

Surya is a 650M-parameter OCR model for extracting text and analyzing document structure. It handles layout, reading order and tables, and supports OCR in 91 languages. Surya 2 returns page content as structured blocks that can include HTML, polygons, bounding boxes, confidence values and reading order. Table recognition can provide row and column geometry; full mode can also return HTML with spanning cells and header rows. Equations found in page OCR are represented as KaTeX-compatible LaTeX within math tags. Users can work with a Python package, command-line tools or an interactive Streamlit app for images and PDFs. Layout, OCR and table recognition require an inference backend: vLLM on NVIDIA GPUs or llama.cpp on CPU and Apple Silicon, or a connection to an existing server. Surya is free and open source. The code uses Apache 2.0, while the model weights have a separate modified AI Pubs Open Rail-M license with commercial-use conditions. It is specialized for documents, not photos or natural scenes.

Tungsten OmniPage converts paper documents, PDFs, and images into editable and searchable digital files. Its recognition capabilities include OCR, ICR, and barcode recognition, alongside PDF compression. OmniPage Ultimate can batch-process files from folders or email and route results into preprogrammed workflows; it recognizes more than 120 languages and works with mobile and desktop scanners, all-in-one devices, and multifunction printers. Standard edition output includes PDF, Microsoft Office, Corel WordPerfect, and HTML, with the option to send converted documents to Amazon Kindle. OmniPage Server supports redaction, password protection, and document encryption. The desktop editions are Windows-only, and Ultimate is not compatible with Mac. For developers, the Capture SDK provides APIs to add OCR and imaging features to applications; it is offered for Windows, Linux, and Mac and can be deployed on-premises, in containers, or on cloud platforms such as Microsoft Azure and Amazon Web Services. OmniPage is paid software with a free trial and no free plan. Individual desktop license customers receive unlimited technical support access during their first year, subject to the stated support scope.
