Nanonets OCR Small

Dealing with complex documents – research papers, legal contracts, financial reports, medical forms – often means facing the challenge of extracting meaningful data trapped within images and unstructured layouts. Traditional Optical Character Recognition (OCR) tools can pull out plain text, but they frequently miss critical elements like tables, equations, signatures, or the context of images, leaving you with data that’s difficult to process or use effectively, especially for modern AI workflows.

Nanonets-OCR-s is designed to overcome these limitations. This state-of-the-art image-to-markdown OCR model goes beyond simple text extraction, offering intelligent content recognition and semantic tagging. It understands the structure and context of your documents, transforming them into rich, structured markdown output that’s immediately ready for downstream tasks, particularly processing by Large Language Models.

Key Features

Nanonets-OCR-s provides powerful features to unlock the full value of your document data:

• 📐 LaTeX Equation Recognition: Automatically converts mathematical expressions and formulas found within documents into correctly formatted LaTeX syntax, preserving the integrity of complex scientific and technical content.

• 🖼️ Intelligent Image Description: Describes images embedded in documents (like charts, graphs, or logos) using structured tags (<img>), making visual information accessible and understandable for automated processing and analysis.

• ✍️ Signature Detection & Isolation: Accurately identifies and isolates signatures within documents, tagging them with <signature> for easy handling in legal, financial, and business workflows where signature verification or identification is crucial.

• 💧 Watermark Extraction: Detects and extracts watermark text, tagging it with <watermark>. This allows for clear separation of core content from background elements.

• ✅ Smart Checkbox Handling: Converts checkboxes and radio buttons from forms into standardized Unicode symbols, tagged with <checkbox>. This ensures consistent data capture for forms and surveys.

• 📊 Complex Table Extraction: Extracts structured data from complex tables, converting them into both markdown and HTML formats. This preserves the tabular structure, enabling easy data analysis and integration.
