Build a Spider Diagram From Your Material

Turn your notes or topic into a radiating diagram that is ready to study and share.

Starts from your files

Upload a PDF, Word, PowerPoint, text or image file, and the AI finds the categories to plot.

Clear axes and branches

Each axis holds one category, so you can compare strengths and gaps at a glance.

Quiz and export next

Turn the diagram into a quiz, add flashcards from the same notes, or export as PNG or PDF.

How a Free Spider Diagram Gets Made

Three steps from raw material to a finished diagram you can refine.

  1. 1

    Add your material

    Upload your file or type the topic and the categories you want to compare.

  2. 2

    AI draws the diagram

    The AI sets the central idea and places each category on its own radiating axis.

  3. 3

    Study, expand or quiz

    Expand any axis, edit labels, then export or test yourself with a quiz.

What a Free Spider Diagram Shows

A spider diagram is a visual that places a central idea in the middle and draws several axes outward, one per category. Each axis is scaled, so a value near the centre is low and a value near the edge is high. Connecting the points on each axis forms a web shape, which makes strengths, gaps and balance easy to compare across categories.

  • Central axis: the subject or overall comparison
  • Radiating axes: one category or criterion each
  • Scale rings: shared intervals that make values comparable
  • Plotted points: the score for each category on its axis
  • Web outline: the shape that reveals patterns and imbalances

Use the shape to spot the categories that need work, then review each axis in turn. Create your own version from your notes to see your data in this format.

Free Spider Diagram Questions

Answers about how spider diagrams work and how to make one.

What is a spider diagram used for?

A spider diagram compares several categories or criteria for one subject. The shared axes make it quick to see which areas score high or low and where a profile is lopsided.

Is a spider diagram the same as a radar chart?

The names are often used for the same shape. Both plot values on radiating axes that meet at a centre, and the web outline shows how the values compare across categories.

Can I make a free spider diagram from my own notes?

Yes. Upload a PDF, Word, PowerPoint, text or image file, or type a topic, and the AI draws a diagram with branches you can edit and export.

Can the diagram be turned into a quiz?

Yes. Once the map is built, you can turn it into a quiz to test yourself on the categories and details it contains.
