Document understanding combines reading with interpretation. A system may identify text, tables, images, page layout, measurements, relationships, and the purpose of different sections rather than treating the document as an undifferentiated block of words.
The extracted information can support later tasks such as summarization, data entry, design, or scene construction. Accuracy depends on document quality, clear structure, visual reasoning, and whether important details are represented unambiguously.

Document understanding means an AI helper can read a document and work out what its different parts mean. It looks beyond individual words to understand how the information fits together.
For example, it could read a floor plan, recognize room labels and measurements, and use those details to help create a rough digital layout of the building.
How is document understanding different from text extraction?
Text extraction copies visible words, while document understanding also interprets structure, relationships, layout, and meaning.
What documents can AI systems interpret?
Depending on the system, examples include reports, forms, diagrams, brochures, tables, presentations, and scanned pages.
