DOCUMENT GUIDE

Extract document fields into JSON

Preset patterns identify candidate fields such as invoice numbers, amounts and dates. Missing or ambiguous values need manual review. This is source-based extraction, not a guarantee of complete accounting or legal data.

  1. Choose a supported PDF, text file or scan.
  2. Select Invoice, Contract, Resume or Research paper and extract candidate fields.
  3. Compare fields with the source, correct JSON and download the validated result.

Free access and limits

No account or payment. One document up to 4 MB, 10 PDF pages and 60,000 extracted characters. Original source tools run on our server without a generative model.

Optional AI summaries and questions use the configured provider displayed before processing. Free AI accepts up to 32,000 UTF-8 source bytes and 3 requests per network per UTC day, subject to a shared site budget and availability. Shared networks share an allowance.

Before AI processing, you must consent to send extracted text and your question to the provider. AI results and OCR can contain errors.
