π·οΈ Meta Fields
Meta fields extract generic document information β things like the filename, sender email address, email subject, or full document content β rather than data from the document body itself.
How they differ from schema fields
Regular extraction schema fields extract structured data from the document content (e.g. invoice number, total amount, line items). Meta fields are defined once at the inbox level and are automatically populated for every document that arrives β no AI extraction involved.
Where to find them
Meta fields are managed on the Extraction Schema page, under the Meta Fields tab.

Notes
Meta fields appear alongside your regular schema fields in exports, webhooks, and integrations
Their values come directly from document metadata β they are not re-extracted by AI on reprocessing
