Surya

App in the BluixApps catalog

What it is

Surya OCR is Datalab's modern document AI toolkit — multilingual OCR (90+ languages), layout analysis, reading order detection, and table recognition in one package. Significantly higher accuracy than Tesseract on real-world documents (magazines, forms, scanned photos).

The 2024 generation of document AI, the canonical alternative to Tesseract for modern OCR workflows.

What it's for

  • Multi-language OCR — 90+ languages
  • Layout analysis — section blocks (title, paragraph, table, figure)
  • Reading order detection — correct text flow on complex pages
  • Table recognition — extract structured tables
  • Form processing — extract key-value pairs
  • Document classification — by content type

Who it's for

  • Document AI teams processing real-world inputs
  • Legal / contract platforms OCRing scanned documents
  • Operula digitizing artisan documentation, certificates
  • Invoice / receipt processing workflows
  • Academic researchers processing historical documents
  • Hosting providers offering document AI tier

Why teams pick Surya OCR over alternatives

  • GPL-3.0 — fully open
  • Better than Tesseract on modern documents (forms, magazines, screenshots)
  • Built-in layout + table — Tesseract requires plugins
  • 90+ languages — broad coverage
