Frequently Asked Questions

Does this use ChatGPT or any external AI?▼
No. The summarization runs entirely in your browser using a lightweight TextRank-inspired algorithm. No data is sent to any server or API — your documents remain 100% private.
How accurate is the summary?▼
The tool uses extractive summarization, meaning it selects the most important sentences from your document rather than generating new text. This ensures accuracy since every sentence comes directly from your PDF.
Does it work with scanned PDFs?▼
No — the tool extracts embedded text. Scanned PDFs that contain only images won't produce usable text. Use OCR software first to convert scans to searchable PDFs.
