 **Remote services**
 If your parser sends document content to a remote service, declare it:
 ```python

 Paperless-ngx excludes such parsers when the document being consumed has not
 been marked for remote processing, so users can keep remote OCR off by default
 and enable it selectively with a workflow. Parsers that do not declare the

 ##### Remote OCR {#workflow-action-remote-ocr}
 "Remote OCR" actions send the document to the configured remote OCR engine instead of processing it
 locally. To use remote OCR selectively, set the [remote OCR mode](configuration.md#PAPERLESS_REMOTE_OCR_MODE)
 to `workflow_only` then add this action to a workflow that matches only the documents you
 want sent to the remote engine. See [Remote OCR](#remote-ocr) for the engine setup. The action only works with
 a **Consumption Started** trigger.
 The action takes no options, its presence is what enables remote OCR for a matching document.
 If the remote engine is not configured, or does not support the document's file type, the document is
 processed locally instead and a warning is written to the log.
 #### Workflow placeholders

 settings can be supplied as environment variables or via **Application Configuration**.
 Additionally, when using a commercial service with this feature, consider both potential costs as well as any associated file size
 or page limitations (e.g. with a free tier).
 By default, every document of a supported file type is sent to the remote engine. To use it more selectively, set the
 [remote OCR mode](configuration.md#PAPERLESS_REMOTE_OCR_MODE) to `workflow_only`. Documents are then processed locally
 unless a [remote OCR workflow action](#workflow-action-remote-ocr) enables it for them, so you can limit the remote
 engine to particular documents.
 Setting the mode to `workflow_only` also allows the **Reprocess** actions to selectively use remote OCR for individual documents.

Trenton HandGitHub	0e5fbc973a	Enhancement: prefer existing tags, types, correspondents, and storage paths in AI suggestions (#13676 ) AI Suggestions previously invented near-duplicate metadata because the classification prompt had no knowledge of the installation's own taxonomy. This surfaces a small, ranked, permission-filtered set of existing tags/document types/correspondents/storage paths - drawn from the document's RAG neighbors plus its own already-assigned metadata - so the model prefers reusing what already exists. The LLM response schema now returns existing_ids (IDs of reused candidates) separately from new_names (genuinely new suggestions). Only new_names goes through localization and fuzzy name-matching; existing_ids is resolved deterministically and never touched by the localization pass, so exact matches can no longer be silently corrupted by translation.	2026-08-14 15:51:34 -07:00
