+#### Processed Mail
+
+Paperless keeps track of emails it has processed in order to avoid processing the same mail multiple times. This uses the message `UID` provided by the mail server, which should be unique for each message. You can view and manage processed mails from the web UI under Mail > Processed Mails. If you need to re-process a message, you can delete the corresponding processed mail entry, which will allow Paperless-ngx to process the email again the next time the mail fetch task runs.

 #### OAuth Email Setup
 
 Paperless-ngx supports OAuth2 authentication for Gmail and Outlook email accounts. To set up an email account with OAuth2, you will need to create a 'developer' app with the respective provider and obtain the client ID and client secret and set the appropriate [configuration variables](configuration.md#email_oauth). You will also need to set either [`PAPERLESS_OAUTH_CALLBACK_BASE_URL`](configuration.md#PAPERLESS_OAUTH_CALLBACK_BASE_URL) or [`PAPERLESS_URL`](configuration.md#PAPERLESS_URL) to the correct value for the OAuth2 flow to work correctly.

+## Document Suggestions
+
+Paperless-ngx can suggest tags, correspondents, document types and storage paths for documents based on the content of the document. This is done using a (non-LLM) machine learning model that is trained on the documents in your database. The suggestions are shown in the document detail page and can be accepted or rejected by the user.
+
+## AI Features
+
+Paperless-ngx includes several features that use AI to enhance the document management experience. These features are optional and can be enabled or disabled in the settings. If you are using the AI features, you may want to also enable the "LLM index" feature, which supports Retrieval-Augmented Generation (RAG) designed to improve the quality of AI responses. The LLM index feature is not enabled by default and requires additional configuration.
+
+!!! warning
+
+    Remember that Paperless-ngx will send document content to the AI provider you have configured, so consider the privacy implications of using these features, especially if using a remote model (e.g. OpenAI), instead of the default local model.
+
+The AI features work by creating an embedding of the text content and metadata of documents, which is then used for various tasks such as similarity search and question answering. This uses the FAISS vector store.
+
+### AI-Enhanced Suggestions
+
+If enabled, Paperless-ngx can use an AI LLM model to suggest document titles, dates, tags, correspondents and document types for documents. This feature will always be "opt-in" and does not disable the existing classifier-based suggestion system. Currently, both remote (via the OpenAI API) and local (via Ollama) models are supported, see [configuration](configuration.md#ai) for details.
+
+### Document Chat
+
+Paperless-ngx can use an AI LLM model to answer questions about a document or across multiple documents. Again, this feature works best when RAG is enabled. The chat feature is available in the upper app toolbar and will switch between chatting across multiple documents or a single document based on the current view.
