-This app accepts text and obfuscates names, phone numbers, emails, and IP addresses.
+In many applications, personally identifiable information (PII) is easy to remove from databases since a column may contain specific PII.
+Common techniques like hashing also allow the identity of these values to be preserved without exposing the contents of the value.
+
+However, it can be less straightforward to remove from unstructured text data, where PII may or may not be present.
+Further, text may contain multiple types of PII that present an increased risk of exposure when coupled together.
+For example, a name and IP address together may be used to pinpoint a specific person's location.
+Hashing the data outright is not an option since consumers of these data often prefer to work with the raw text data.
+Thus, preserving privacy in raw text data remains a challenge.
+
+This space applies both rule-based and ML-based approaches to remove names, phone numbers, emails, and IP addresses from raw text.
+This app accepts raw text and returns the same text, but with PII replaced with special tokens that preserve some characteristics of the masked entities without revealing their contents.
