# Document Classification
Automatically identify what a document is before it is extracted. Document Classification detects a document's type and category from its content using an LLM classifier. It can run on its own to sort an unlabeled inbox or run before extraction to route each document to the correct reviewer.
Use the classification workflow in the product UI. This page covers capabilities, formats, limits, and results.
In the product UI, this capability is available under **Capabilities > Classification**.
{% hint style="info" %}
Classification supports single-document, batch, and synchronous workflows, with additional handling for multi-document PDFs, ZIP archives, and multi-sheet Excel workbooks.
{% endhint %}
### Supported classification types
Document Classification uses the platform's shared document type registry.
{% hint style="info" %}
Additional document types can be registered dynamically without a code change. New types are merged at runtime through a YAML configuration file and become available automatically.
{% endhint %}
### Built-in category list
The upload flow includes a built-in category list that can be combined with any custom document types supplied by the caller.

| Capability | Description | Limit |
| ----------------------------- | --------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- |
| Single classification | Classify one document asynchronously. | No additional limit specified. |
| Bulk classification | Classify multiple documents in one asynchronous batch. | 500 MB maximum per ZIP and 100 MB maximum per file within a ZIP. |
| Synchronous classification | Classify one document and return the result immediately. | No additional limit specified. |
| Custom type restriction | Restrict classification to a caller-supplied list of document types. | Supported through `custom_document_types` or a URL to a JSON type list. |
| Multi-document PDF handling | Detect and segment multiple documents within a single PDF. | PDFs with 20 pages or fewer use direct LLM classification; longer PDFs use a homogeneity-check pipeline. |
| Excel workbook classification | Classify each sheet individually, with optional entity mapping. | No additional limit specified. |
| Confidence scoring | Each result includes a confidence score from 0.0 to 1.0. | No fixed pass/fail threshold is defined by the classifier. |
| Search and filter | Search the classification list by ID, type, status, or file type, and filter by status. | No additional limit specified. |
{% hint style="warning" %}
**Confidence scores** do not have a fixed pass/fail threshold in the classifier itself. The score is also used internally to help decide whether a multi-page PDF should go through the homogeneity-check pipeline.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.uptiq.ai/document-ai/guides/document-classification.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
