Complete guide
How to use the AI PDF Summarizer
The AI PDF Summarizer extracts the text from your PDF and passes it to a large language model, which generates a concise, coherent summary tailored to your chosen length and focus. It works on any text-based PDF - reports, academic papers, legal contracts, business plans, ebooks, and more.
The tool works best on text-based PDFs. If your PDF is a scanned document (a photograph of printed pages), it won't have a text layer - run it through PDF OCR first to make the text machine-readable, then summarize it here.
Choose your summary length (Brief, Standard, Detailed) and focus (General, Key Points, Action Items, Conclusions) before submitting. These options shape the AI's output to match your reading goal - a 'Brief / Key Points' summary is ideal for quick triage; a 'Detailed / Action Items' summary is better for project planning documents.
Best document types
Research papers, business reports, contracts, legal documents, annual reports, ebooks, and news articles. Any text-based PDF where you need to understand the content quickly without reading every page.
Limitations to know
Scanned/image PDFs produce poor results - use PDF OCR first. Highly technical documents (medical, legal, financial) may lose nuance. Tables and charts are not included in the summary. Always verify critical details against the source.
Quick checklist
- Confirm your PDF is text-based, not a scanned image.
- For scanned PDFs, run PDF OCR first - then summarize.
- Choose 'Brief' for quick triage; 'Detailed' for thorough review.
- Use 'Action Items' focus for meeting notes, project briefs, and reports.
- Always verify key figures, dates, and legal clauses against the original.
