Why this works
Drop in a PDF and get back a written summary in seconds \u2014 brief bullet points, a standard paragraph, or a detailed multi-section overview. Useful for long reports, contracts, research papers, and anything you don\u2019t have time to read in full.
Long PDFs are everywhere and most don\u2019t deserve a full read. A 60-page quarterly report might need a 4-bullet summary for a meeting prep; a 30-page contract might need a single paragraph identifying unusual clauses; a research paper might need a detailed section-by-section overview if you\u2019re deciding whether to read it fully.
AI Summarize extracts the text from your PDF (running OCR first if the PDF is scanned) and passes it to a language model that produces a written summary at the length you specified. Three length options cover most use cases.
Brief (3\u20135 points) is the right pick for meeting prep \u2014 you want the headline takeaways in under a minute of reading. Output is a bullet list of the document\u2019s most important claims, decisions, or findings.
Standard paragraph is the right pick for daily triage \u2014 you want enough context to decide whether to read the full document. Output is one or two paragraphs covering the document\u2019s purpose, main points, and conclusion.
Detailed is the right pick when you\u2019ll cite the summary in your own writing or need to make a decision based on it. Output is structured by section, walks through the document\u2019s argument or content, and is roughly 600\u20131000 words. It\u2019s still much faster than reading the original but doesn\u2019t skip nuance.
The summary returns as a .md (Markdown) file. Markdown opens cleanly in any text editor, can be copy-pasted into email or Slack with formatting preserved, and converts trivially to Word or PDF if you need it in those formats (using our Markdown-to-PDF tool, for instance).
A few things to know. The summariser doesn\u2019t make up facts \u2014 it summarises only what\u2019s in the document. It can\u2019t answer questions the document doesn\u2019t address. For very long PDFs (over ~80 pages) the summary may smooth over distinctions between sections; consider using Extract Pages to break long documents into thematic chunks and summarising each separately.
For sensitive documents (contracts under negotiation, personal medical records, etc.), be aware that AI summarisation involves sending the text content to a language model service. PDFRun routes the content through our infrastructure under the same one-hour deletion policy as every other tool, but the text is processed by a third-party AI service. If your document is highly sensitive, consider whether AI summarisation is the right tool versus reading the document directly.

Real-world uses
Executives
Meeting prep: a 60-page quarterly report becomes a 4-bullet brief in 20 seconds.
Lawyers
Triage of long contracts \u2014 spot unusual clauses in a Standard paragraph before deciding whether full review is needed.
Researchers
Decide whether a 30-page paper is worth reading in full based on a Detailed section-by-section summary.
Investors
Filter through a stack of pitch decks or earnings reports quickly to find the ones worth a full read.
Common questions
How accurate is the summary?
For straightforward documents (reports, articles, contracts), accuracy is high \u2014 the model summarises what\u2019s actually in the text without making up facts. For nuanced or argumentative documents, the Detailed setting captures more of the original\u2019s subtlety than Brief. The model never hallucinates content that isn\u2019t in the source.
What format is the output?
Markdown (.md). It opens in any text editor, copies cleanly into Slack and email with formatting preserved, and converts trivially to Word or PDF using our Markdown-to-PDF tool.
Does it work on scanned PDFs?
Yes. Scanned PDFs run through OCR first to extract the text, then the summary runs on that extracted text. Accuracy on the summary tracks accuracy of the OCR; clean modern scans produce summaries indistinguishable in quality from born-digital sources.
How long can the source PDF be?
Practically: 80\u2013100 pages produces the best summaries. Longer documents are summarised but may smooth over distinctions between sections \u2014 consider breaking very long PDFs into thematic chunks using Extract Pages and summarising each separately.
Is my document private?
The PDF travels over HTTPS to our servers and is deleted within one hour. The extracted text is processed by a third-party AI service to generate the summary. If your document is highly sensitive, weigh whether AI summarisation is appropriate versus reading the document directly.
Can I ask follow-up questions about the document?
Not in this tool \u2014 AI Summarize produces a single written summary, not an interactive chat. For document Q&A, the summary often answers the most common questions; for deeper exploration, search the source PDF directly (Cmd-F after OCR if it was a scan).
