PDF to Markdown for NotebookLM
Prepare your PDF for NotebookLM: clean Markdown, redacted personal data and a token count. All on your device.
About this tool
NotebookLM 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 NotebookLM, 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.
NotebookLM works with sources you upload to Google. Converting and anonymizing first lets you upload only the text you choose, never the original PDF.

Questions
- Can't NotebookLM read the PDF directly?
- Many assistants accept PDFs, but uploading sends the file to their servers. With Sırdaş the PDF never leaves your machine: you only share with NotebookLM the anonymized text you choose to paste.
- Which data is hidden before pasting into NotebookLM?
- ID and passport numbers, tax IDs, emails, phones, dates, addresses, cards, medical record numbers and labelled names (patient, landlord, signed by…). Detection is automatic and can miss items: review the result.
- How do I know the token count?
- We show an estimate (about 4 characters per token). It is indicative; each model counts slightly differently.
