What can AI document extraction pull from a file?

It extracts plain text, tables, and named fields — invoice numbers, totals, dates, addresses, and line items — plus signatures and checkboxes on forms. Most tools output the result as JSON, CSV, or spreadsheet rows you can feed straight into accounting, CRM, or database systems.

How is it different from traditional OCR?

Classic OCR only converts pixels to characters, leaving you a wall of text to parse yourself. AI extraction adds layout understanding and language models, so it knows a number is the tax amount and a date is the due date, returning labeled fields instead of raw text — even across varied layouts it hasn't seen before.

How accurate is it, and can I trust it with sensitive documents?

Accuracy is high on clean, typed documents but drops on poor scans, handwriting, or unusual layouts, so most tools attach confidence scores and support human review of flagged fields. For sensitive files, check where documents are processed and stored, whether your data trains the vendor's models, and whether the tool offers redaction or on-premise deployment.

What is AI document extraction?

AI document extraction reads unstructured documents — PDFs, scans, photos, and forms — and pulls out text, tables, and specific fields as structured data. It combines OCR with layout understanding and language models, so it captures not just characters but what each value means, like an invoice total or a due date. The output is usually JSON, CSV, or spreadsheet rows ready for a database or workflow.

How does AI document extraction work?

First OCR converts the page image into text while a layout model maps where each block sits — tables, headers, and fields. A language or vision model then interprets that structure, matching values to the fields you asked for, whether from a fixed template or a schema you describe. Many tools return a confidence score per field and route low-confidence ones to a person for review.
