The proposed online PDF to TNS converter tool will provide users with a convenient way to convert PDF documents to TNS format, facilitating the creation and editing of mathematical documents. The tool will use a combination of OCR and NLP techniques to extract and analyze content from PDF documents, and generate TNS files that can be edited and typeset using TeX-based systems.

In today's digital age, documents are created and shared in various formats, including Portable Document Format (PDF) and TeX Notebook Source (TNS). While PDF is a widely used format for sharing and viewing documents, TNS is a format used for typesetting and creating mathematical documents. However, there is a need for a tool that can convert PDF documents to TNS format, especially for users who want to edit or typeset mathematical content in their documents. This paper proposes an online PDF to TNS converter tool that can facilitate this conversion.

PDF is a popular format for sharing and viewing documents, as it preserves the layout and formatting of the original document. However, it is not an editable format, and users often need to convert PDF documents to other formats for editing or typesetting purposes. On the other hand, TNS is a format used for creating and editing mathematical documents, particularly in the TeX typesetting system. TNS files contain source code that can be compiled to produce high-quality mathematical documents.
