About this tool
DeepSeek answers better with well-structured text: headings, lists and paragraphs, without repeated headers or stray page numbers. We turn your PDF into Markdown with that structure and estimate the tokens so you know whether it fits in one conversation.
Before you paste anything into DeepSeek, personal data is replaced with consistent placeholders ([NOMBRE_1], [DOCUMENTO_1]…): the same value always gets the same placeholder, so the model understands the document without knowing the people.

When you do not need Sırdaş
If the document holds nobody's data and DeepSeek accepts the PDF, upload it directly: it is faster. Sırdaş is for PDFs with names, ID numbers or accounts, or when you do not want the whole file to leave your machine.
