AI Summarizer Online Free & Securely

Quickly generate concise summaries from articles, paragraphs, and essays, providing clear and precise key points in seconds.

Upload a PDF, article, or long passage and PDFSketch's AI reads the full text to generate a concise summary with the key points pulled out in seconds.

How it works

  1. Upload your document — Select the PDF or paste in the text you want summarized.
  2. AI generates the summary — The model reads the full content and extracts the key points, arguments, or findings.
  3. Review and copy — Read the generated summary, adjust length if needed, and copy or download it.

Key features

  • Adjustable Summary Length — Choose a short key-points version or a longer paragraph-style summary depending on your need.
  • Long-Document Support — Handles multi-page reports and long articles, not just short excerpts.
  • Key-Point Extraction — Surfaces the main arguments or findings rather than just shortening sentences mechanically.
