How does AI document extraction work?
AI document extraction combines OCR, layout analysis, document classification, schema-guided extraction, validation rules, and review routing to convert document content into reliable structured output.
Short answer
AI document extraction combines OCR, layout analysis, document classification, schema-guided extraction, validation rules, and review routing to convert document content into reliable structured output.
What this means in practice
A production pipeline usually detects the document type first, then chooses the right schema or extractor. The model reads the document in context, extracts values, attaches confidence, and validates the result before export.
Hard cases may use multimodal models, deterministic checks, and human review for low-confidence fields.
