Folio turns unstructured documents into structured data. Upload a file, and retrieve a typed JSON result via polling or webhook.
  • What it does — reads PDFs, images, and scanned documents; identifies the document type; and pulls out named fields with per-field confidence scores.
  • Who it’s for — health-tech teams that need reliable, privacy-preserving extraction from clinical and administrative documents at scale.
  • Where it runs — Azure Canada Central, Law 25-aligned, with optional de-identification.

How it works

Processing is asynchronous. A POST /v1/documents call returns a 202 with a document id almost instantly. The structured result is ready seconds to minutes later — retrieve it by polling or by subscribing to a webhook.
