Tip: you can also load a PDF below to auto-fill this field (only works if the PDF contains selectable text).

PDF (optional)

If your PDF is a scanned image, there is no selectable text → it will extract nothing (OCR not included).

Summary

This summarizer uses a simple extractive method (sentence scoring). It works great for articles, notes, reports and long messages — but it won’t perfectly preserve complex structure like tables.

Everything runs on your device: your text and your PDF never leave your browser.
