# Smart blur

### What is smart blur?

Smart Blur allows you to automatically blur or redact sensitive information, such as emails, names, prices, or personal data, while recording a Supademo.

It’s especially helpful when capturing dashboards, CRMs, analytics tools, or any app containing Personally Identifiable Information (PII).

Rather than manually editing each slide, Smart Blur detects and hides sensitive content in real-time, saving you time and ensuring viewer safety and professionalism.

Smart Blur is currently only supported when using the **Supademo Chrome Extension**.

**Here's an overview of how to use Smart Blur:**

* To enable Smart Blur, open the **Supademo Chrome Extension** and toggle on **“Smart Blur”** before starting your recording. Once enabled, Smart Blur will automatically detect and blur common patterns like emails, numbers, and currency values during the capture process.
* Proceed to record your Supademo as usual—Smart Blur will run in the background and apply redaction automatically.

### Select & blur custom elements

You can also select **custom elements** to blur before or during a Supademo recording. Here's a quick walkthrough of how to use the select & blur functionality:
