| Ask Fern can now mask personally identifiable information in a user's question. When enabled, structured PII (emails, phone numbers, SSNs, and credit card numbers) is redacted in the browser and never sent to Fern. |

| When `true`, personally identifiable information in a user's question is masked client-side before the question is sent to Ask Fern. Leave it off if your users search with sample PII, since masking redacts those strings before search runs and the queries won't return results. |
