  Google Cloud's Document AI product page, describing a platform of pretrained and custom processors that extract structured entities from documents. Establishes a managed Google Cloud service with no published implementation.

No usage figure is published for this service specifically, and it publishes no countable artifact - no package, repository or registry entry - so no level is assigned rather than one being inferred from the vendor's platform as a whole.

  The product page, read for a usage disclosure; it publishes none specific to this service.

Google Document AI's custom processors return typed entities that a customer defines, such as an invoice total or a field on a form they trained the processor on, rather than just the position of text on the page. Docling matches it through its template-driven extractor, which returns the fields a user defines without training anything on the user's own forms.

  Google Cloud's Document AI product page lists a "Custom extractor" priced under "Extract structures and entities from documents" and says custom classifier and splitter processors can be "trained from the ground up using your own documents and custom classes".

  The custom extractor overview states "Custom extractor extracts entities from documents of a particular type." and that its goal is "to enable Document AI users to build custom entity extraction solutions for new document types for which no pre-trained processors are available".
