The Diagrams Are the Assessment
Most AI question tools only read text — so they ignore the diagrams, circuits, plots, and figures that carry the actual concept. In technical and scientific subjects, that illustration is exactly the part you need to assess. QuestionForge's AI vision reads the pages you choose, extracts the figures, and builds questions that reference them.
How Diagram Question Generation Works
Upload a document
A PDF or Word file that contains diagrams, charts, or figures.
Choose “Diagrams & figures”
Select the pages to read; AI vision scans them for illustrations.
Get figure-based questions
The relevant illustration is extracted and attached to each question it belongs to.
See What Text-Only Tools Miss
- AI vision figure extraction
Diagrams, charts, and figures are detected and pulled straight from the page — not skipped.
- Figures attached to questions
The extracted image sits with the question that references it, ready to review, export, and deliver.
- Handles complex & scanned pages
Works where plain text extraction fails — dense technical layouts and scanned documents included.
- Reuse without re-charging
Pages already processed for text can have figures added on demand, without paying to read them again.
- Bring your own images
Snapped photos or scans? Combine them into a single PDF and import them together — the app guides you through it.

Frequently Asked Questions
Can it make questions from diagrams in a PDF?
Yes. AI vision reads the pages you select, extracts the figures, and builds questions that reference them.
Does the diagram get attached to the question?
Yes — the extracted figure is attached to the question that uses it, so it travels with the question into exams and exports.
What kinds of figures work?
Charts, plots, circuit and system diagrams, scientific illustrations, maps, and labelled images.
I only have photos of pages — can I use those?
Combine them into a single PDF and upload it; QuestionForge reads the pages together.
Do I pay again if I already processed those pages?
No. If a page range was already read for text, figure extraction is added on demand without re-charging for the original read.
