About the PDF Summarizer
Deciding whether a long document needs your full attention is a real task in itself. A sixty-page report, a supplier agreement or a policy consultation each need triage before they need reading, and the confidentiality of the material often rules out pasting it into an online AI service.
This summariser is extractive: it reads the document’s text in your browser, scores each sentence by how much of the document’s significant vocabulary it carries, and returns the highest-scoring sentences in their original order. There is no AI service involved and nothing is transmitted — the sentences you get back are verbatim from your document rather than generated text, so nothing is invented.
It's part of the PDF collection on Toolzy, a growing platform of 135+ free, privacy-first tools built for speed and a great experience on every device.
Also known as: summary, tldr, ai, pdf.
