Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How does the AI PDF Summarizer work client-side?
We extract the text layer from your PDF using the pdf.js page text stream reader. The extracted text is then normalized and scored using a local Term Frequency-Inverse Document Frequency (TF-IDF) sentence ranking algorithm to compile key summary bullet points.
Does this tool upload my documents to external AI servers?
No, the summarization runs 100% locally in your browser memory (RAM) using client-side JavaScript. Your confidential files are never transmitted to any external AI service.
Are scanned PDF documents supported?
This summarizer reads native digital text layers. If your PDF is a scanned document with no text layer, you will need to perform OCR on it first to extract the text.
