Blur Sensitive Data

Overview

VibeCheck's blur feature lets you hide sensitive information — passwords, emails, personal data, API keys — so it never appears in shared bug reports. Blur works in two ways: live blur during screen recordings and annotation blur on screenshots.

Live blur during recording

Blur elements on the page in real-time before they are captured in the video. Sensitive data is never recorded.

How it works

1. Start a screen recording
2. Click the Blur Elements button in the recording controls
3. Recording pauses and a blue banner appears: "Click elements to blur"
4. Click any element on the page to blur it (applies a blur(10px) CSS filter)
5. Click a blurred element again to unblur it
6. Click Done to resume recording — blurred elements stay blurred throughout

Key details

• The cursor changes to a crosshair and elements highlight on hover so you can see what you're about to blur
• Use Unblur All to remove all blurs at once
• Blurs persist for the duration of the recording
• Because the blur is applied at the CSS level, the sensitive content is never present in the video frames

Blur tool for screenshots

After capturing a screenshot, use the blur tool in the annotation editor to redact regions of the image.

How it works

1. Capture a screenshot
2. In the annotation editor, select the Blur tool (eye-off icon)
3. Click and drag to draw a rectangle over the area you want to hide
4. The selected area is replaced with a blurred version of the underlying image
5. Resize or move blur regions as needed
6. Click Save — the blur is baked into the exported PNG

Key details

• Blur regions are movable and resizable like other annotations
• The blur is permanent once saved — the original pixels are not recoverable from the exported image
• Works alongside other annotation tools (arrows, text, rectangles, etc.)

When to use each approach

Tips

• Blur before recording whenever possible — it's the safest approach since sensitive data never enters the video
• Use blur on screenshots for quick redactions after capture
• Combine blur with other annotation tools to both redact sensitive data and highlight the bug
