# PII Detection

Logikcull automatically detects Personally Identifiable Information (PII) as part of our world-class processing engine. For a list of PII types that Logikcull identifies, see [PII Types in Logikcull](/logikcull/docs/pii-types-in-logikcull).

Certain PII features are available exclusively on an annual subscription plan. Please contact the support team for details.

## What is PII detection in Logikcull?

Logikcull automatically scans document text for Personally Identifiable Information, or PII, on all eligible files uploaded into your project. A PII Detected Auto Tag (QC Tag) is assigned to documents in which PII is detected with a 75% or greater confidence level. The document count for PII detected will appear as a Auto Tag on the upload card after processing.

## Filtering on the PII Detected Auto Tag

To filter your documents by PII Detected, just select that filter facet from the list in your Auto Tags filter:

**ℹ️ The following PII functionality is available to exclusively to customers on an annual subscription plan.**

## Searching and filtering PII

### Running searches on PII

You can run a syntax-based search easily by selecting a PII Type from the Advanced Search Builder.

Searches can also be constructed directly from the main search bar by using the field syntax `pii_types:` and searching on a specific field name, like `pii_types:”passport_number”`. A list of available PII types can be found in [PII Types in Logikcull](/logikcull/docs/pii-types-in-logikcull).

### Filtering PII

From the main search page, navigate to the PII Types filter and select one or more of the available filter facets to filter on PII types.

## Frequently asked questions

1. **What documents are eligible for Auto Tag-based PII detection?** *The document must be English-language recognized text and must have an extracted text style or OCR style smaller than 1 GB in size.*
2. **My document has PII Detected but doesn’t have PII, or doesn't have PII Detected but contains PII.** *While we have generally seen reliable performance, PII Detection is an artificial intelligence based on machine learning and is not 100% perfect.*
3. **How would I know if a document failed PII detection?**

*We assign the PII Detection Failed Auto Tags to documents that fail PII detection.*
