There are two fundamentally different ways to summarize a document. Extractive summarization pulls out the sentences that already exist in the text and are judged most representative, stitching them together without changing a word — fast and low-risk, but often choppy since sentences written for a full-length document rarely flow well when yanked out of context. Abstractive summarization, which is what this tool and most modern AI summarizers actually do, reads the whole document and generates new sentences that condense the meaning in the model's own words. It reads far more naturally and can compress ideas an extractive approach could never combine into one sentence, but it also means the output is a paraphrase, not a quote — worth remembering before you cite a summarized figure or clause as if it were the document's exact wording.
This tool generates abstractive summaries in three formats: a short 3–5 sentence overview for a fast gut-check on relevance, a detailed multi-paragraph breakdown that preserves section-level structure and nuance, and a structured bullet-point list for scanning a document's key claims at a glance. Beyond summarizing, the "Chat with PDF" feature lets you ask direct questions and get answers sourced from the document itself, and a Quiz Generator turns the material into multiple-choice questions for self-testing. All three features work from the same extracted text, so a good summary and an accurate quiz question depend on the same thing: a PDF with real, selectable text rather than scanned page images.
A genuinely good summary does three things a mediocre one does not — it preserves the document's actual conclusions rather than just its topics, it keeps numbers, dates, and named entities intact rather than rounding them away, and it flags where the source document itself expresses uncertainty rather than smoothing that over into false confidence. That is the standard this tool is built to hit, though any AI summary is still a compression of the original and worth a skim-read against the source before you rely on it for something consequential.
Upload your PDF by dragging it onto the upload area or clicking to browse. Text is extracted from the document directly in your browser using a PDF parsing library, so the raw file itself is never required to leave your device just to pull the text out of it — only the extracted text is sent onward for AI processing. Once extraction completes, pick a summary format and click "Generate Summary"; the model reads the full extracted text (up to roughly 60,000 words, about 240 pages) and produces an abstractive summary in the chosen format. The "Chat with PDF" feature works differently under the hood: rather than re-reading the entire document on every question, it retrieves the passages most semantically relevant to your specific question first, then answers based only on that retrieved context — the same retrieval-augmented approach used in most modern document Q&A systems, which is what keeps answers grounded in your actual PDF instead of the model's general knowledge. The Quiz Generator runs a similar process, scanning the extracted text for the concepts most central to the document before drafting multiple-choice questions around them.
Upload your PDF
Drag and drop a PDF onto the upload area, or click to browse. Text extraction happens directly in your browser before anything is sent onward for AI processing.
Choose a summary format
Pick a short overview for a fast relevance check, a detailed multi-paragraph summary that preserves section structure, or a bullet-point list for scanning key claims quickly.
Click Summarize
The AI reads the extracted document text and generates an abstractive summary in your chosen format, typically within a few seconds for most document lengths.
Read and spot-check the summary
Review the generated summary against sections of the original that matter most to you, especially any numbers, dates, or conclusions you plan to act on or cite elsewhere.
Ask follow-up questions in Chat with PDF
Type a specific question about the document and get an answer grounded in the retrieved passages most relevant to it, rather than a generic response.
Generate a quiz to test retention
Choose 3, 5, or 10 multiple-choice questions built from the document's core concepts, answer them, and see your score with the correct answers highlighted.
Copy or export what you need
Copy any summary section to your clipboard, or export it as a plain text file to drop into a report, email, or notes app.
Research & Academia
Summarize lengthy research papers and academic reports to quickly assess relevance before committing to a full read, then use Chat with PDF to check whether a paper actually addresses your specific research question before citing it.
Legal Documents
Get a quick overview of contracts, agreements, and legal filings without reading every clause manually, then ask direct questions about specific terms — termination conditions, renewal dates, liability caps — and verify the answer against the actual clause before relying on it.
Business Reports
Extract key insights from annual reports, market analyses, and lengthy proposals in seconds, with numbers and named entities preserved rather than smoothed over, so the summary stays useful for an actual decision rather than just a general impression.
Student Study
Summarize textbook chapters and lecture notes into concise bullet points for faster revision, then generate a quiz from the same material to check whether the concepts actually stuck before an exam rather than just recognizing them on re-read.
News & Publications
Digest industry whitepapers, policy documents, and long-form reports without reading every paragraph, while the caveat-preserving summary style keeps hedged claims from reading as more certain than the source document actually states.
Medical & Technical Docs
Summarize clinical guidelines, technical manuals, and specification documents to locate the relevant section faster, then use Chat with PDF to pull a specific dosage, parameter, or spec directly from the source text instead of hunting through pages manually.
Three Summary Formats for Different Needs
A short overview for a fast relevance check, a detailed multi-paragraph summary when nuance and section structure matter, or a bullet-point list for scanning key claims — you pick the format that matches what you are about to do with the information.
Chat Answers Are Retrieved, Not Recalled from Memory
Each question triggers a search through your document for the most relevant passages first, and the answer is generated from that retrieved context — the same grounding approach used in production document-Q&A systems, not a guess from general training knowledge.
Built-in Quiz Generator for Active Recall
Turn any PDF into a multiple-choice quiz built from its core concepts to test comprehension and retention — genuinely useful for students and training teams beyond just reading a passive summary.
Numbers and Caveats Are Preserved, Not Smoothed Over
A good summary keeps figures, dates, and named entities intact and reflects uncertainty the source document itself expresses, rather than flattening a preliminary finding into a confident-sounding claim.
Session Privacy by Design
Extracted text is held only for your session and automatically deleted within 24 hours — there is no long-term document archive building up on the server behind the scenes.
Handles Genuinely Long Documents
Processes PDFs up to 25 MB and roughly 240 pages of extracted text, which covers the large majority of contracts, reports, theses, and manuals people actually need summarized.
Turn any PDF into an instant knowledge test with the built-in Quiz Generator. After uploading your document, choose 3, 5, or 10 questions and let the AI create focused multiple-choice questions based on the core concepts of your PDF — not random trivia pulled from incidental details. Each question includes four options with exactly one correct answer, generated from the same extracted text used for summaries and chat, so a quiz question about a contract's termination clause or a paper's methodology section reflects what the document actually says. Select your answers, skip anything you are unsure about, and submit to see your score with correct answers highlighted immediately afterward. It works well as a self-check after reading a chapter, a quick way to verify a summary actually captured the material, or a low-stakes way for a training team to confirm a document was actually read rather than skimmed.
