Summarize Long PDFs Without Losing the Source

Choose a structured output to map a lengthy report or paper. The useful result is more than shorter text: it retains a path from a generated point to the extracted source material.

Verify AI Summaries with Clickable Citations

Citation-bearing outputs attach paragraph references to substantive points. Open a citation to inspect the supporting text before quoting a figure or conclusion.

Find the Original Passage Behind an Answer

The built-in source viewer scrolls to the cited paragraph and highlights it. This lets you inspect nearby qualifications and context in the extracted PDF text.

Ask Questions About Your PDF

Choose Customized Question to ask about a particular finding, assumption, or limitation. You can return to a completed document later for another output.

Use AI to Analyze Long Documents

Research papers, reports, specifications, standards, and financial or technical documents can be useful sources when their text can be extracted. Check dates, tables, and consequential claims against the source.

How the AI PDF Summarizer Works

  1. Upload a text-based PDF in Add Analysis.
  2. Choose the output or question you need and start analysis.
  3. Review the generated result and its citations.
  4. Open a citation to see the highlighted supporting paragraph in the source viewer.
