The "Documents" section in the knowledge base is suitable for adding continuous, structured knowledge content such as product introductions, operating instructions, service policies, and user manuals. You can create new documents online, upload local files, or synchronize existing content from HelpLook.
After a document is added, the system will automatically parse the content and break it down into content fragments that AI employees can retrieve. AI employees who have already referenced this knowledge base can directly use the newly added knowledge without needing to republish it.

To access the AI employee whose knowledge needs to be supplemented, click "Configure" in the left-hand menu. In the "Knowledge" area, you can access the target knowledge base in two ways:
After entering the knowledge base, select "Documents" at the top, click "Add Content" in the upper right corner, and then select "New Document," "Upload Document," or "Sync External Content."

Click "Add Content" and select "New Document". In the "Add Document Online" window that opens, fill in the title, and then enter the content in the left-hand editing area. While editing, you can check the display effect of the content in the right-hand preview area. After confirming that everything is correct, click "Save".
The online editor also supports inserting images and videos. Inserted content will be used by the AI as part of the document's knowledge base; if you need the AI to directly send images, audio, video, or attachments in its replies, it is recommended to use the "Materials" option.

Click "Add Content," then select "Upload Document." You can select a file by clicking the upload area, or drag and drop the file directly into the upload area. After selecting a file, please check the file list below; to remove a file, click the delete icon to the right of the file. Once you are sure everything is correct, click "Confirm."
Currently, we support uploading files in PDF, TXT, DOCX, MD, and XLSX formats. The .doc format (older versions of Word documents) is not currently supported ; this format cannot be parsed correctly. Please save the file as .docx or convert it to PDF before uploading. A maximum of 200 files can be uploaded at a time, and each file cannot exceed 100 MB. Please refer to the information displayed on the upload page for specific requirements.

Click "Add Content" and select "Sync External Content". If HelpLook is not yet authorized, the page will display "Unauthorized". Click "Authorize" and follow the on-screen instructions to complete the process.
After entering HelpLook, select the content you want to sync to HelpKnow. The system only syncs content that has been published and has its AI training switch enabled. If the page displays "No sites to sync," please check if the relevant sites have been published and if the content you want to sync has its AI training switch enabled.
After authorization, you can set the automatic synchronization period to "Never", "1 day", "3 days", or "5 days". To get the latest content from HelpLook immediately, click "Sync".
Synchronization rules:

Once added, the document will be displayed in the list on the left. Clicking on the document name will show the system-analyzed segmentation results on the right, including information such as Document, Heading, and the corresponding text.
These slices will serve as the knowledge corpus used by AI employees to retrieve and generate responses, and are not the final response style that users see.

When the knowledge base contains multiple documents, you can drag and drop documents in the document list on the left to adjust their order, making it easier to organize and manage documents according to business needs.

When you need to save or further edit the document content, you can open the corresponding document, click "Export to Word" in the upper right corner, and export the current document as a Word file.

To delete a document, open the document, click the delete button in the upper right corner, and confirm the deletion as prompted.

After adding a document, you can return to the AI employee configuration page and send questions related to the document content in the "Question and Answer Test" to check whether the AI employee can correctly retrieve and use the new knowledge.
It is recommended to use questions that real users might ask, and try using different wording than the original document. For example, if the document states "the goods will be shipped within 2 business days after payment," you can test "how long after placing the order will it be shipped."
If the reply is incorrect, incomplete, or does not use the expected document content, you can click "Not a good answer? Troubleshoot the cause" below the AI reply to view the reason for the problem and optimization suggestions.

When knowledge needs to be understood in context, rather than when a question corresponds to a fixed answer, it is appropriate to use a "document".
If the knowledge consists of clearly defined questions and standard answers, it is recommended to use "Questions and Answers"; if you need AI employees to send images, audio, video, or attachments, it is recommended to use "Materials".
Once the document has been added and processed, if the knowledge base has already been added to AI Staff and published, there is no need to publish AI Staff again, and the newly added or updated document content can be used for knowledge retrieval.
If the knowledge base has not yet been added to the AI employee, you need to add the knowledge base to the corresponding AI employee first, and then republish the AI employee.
Currently supported formats are PDF, TXT, DOCX, MD, and XLSX. The #5 format is not yet supported. If your document is in #6 format, please save it as #7 format using Word, or convert it to PDF and upload it again. A maximum of 200 files can be uploaded at a time, and each file cannot exceed 100 MB.
HelpKnow only syncs content that has been published in HelpLook and has its AI training switch enabled. Please check if the relevant sites have published the content and if the AI training switch for the content to be synced is enabled.
Go to "Sync External Content" and click "Sync" in the HelpLook area to get the latest content immediately.
