PDF Reading Assistant

Upload a paper, report, or technical document to extract its structure and key arguments, then turn the document into a navigable mind map.

Core capabilities

CORE

Document parsing

Recognizes sections, summaries, figures, and references to build a useful content structure.

Key information

Highlights core arguments, important data, and conclusions for close reading or quick review.

Mind maps

Transforms section relationships and knowledge flow into a clear visual hierarchy.

Who it is for

Useful for readers who want structure, key points, and section relationships before deciding where to read a paper or long report closely.

Read the boundary first

Parsing and mind maps assist reading; they may not capture every figure, formula, or footnote. Critical conclusions need checking in the PDF.

Ways to use it

  1. Inspect a paper's structure and argument before choosing the order for methods, experiments, and appendices.
  2. Extract key data from a long report, then return to the source page for tables and qualifications.
  3. Use the mind map as navigation across sections rather than quoting its shortened labels as source text.

How to review the result

  1. Scans, multi-column layouts, equations, and complex tables can reduce parsing completeness.
  2. Highlighted points are a selection and do not imply that unmarked paragraphs lack value.
  3. Verify every quoted number, definition, and conclusion against the PDF page and surrounding context.
