Supported now

Blur sensitive Slack messages, channels, and threads in real time.

Selective Blur watches the main message list, and optionally the channel/DM sidebar and thread reply panel, blurring anything that matches your patterns as it renders, even in a fast-moving, constantly-updating workspace.

What's supported on Slack

The same blur engine as every other supported app, tuned to how Slack renders its messages and channel and DM list.

Selective or full blur

Blur only messages matching your patterns, or every message.

Hover to reveal

Reveal on hover, tracked so it holds up even while scrolling a tall message.

Sidebar blur

Optionally blur the channel and DM list too, not just the open conversation.

Thread blur

Optionally blur replies in the right-side thread panel as well.

Configured from one popup

Click the extension icon while you're on Slack to set patterns, blur mode, intensity, and hover-to-reveal for Slack specifically. A master switch and a per-site switch mean you can turn blurring off everywhere, or just here, without touching your other apps.

Selective blur by regex pattern, or full blur with one click
Blur intensity from a light haze to fully unreadable
Optional channel and DM list blur
Optional thread reply blur

Stop shoulder-surfers from reading your Slack messages.

Install Selective Blur and set your patterns once. It takes less time than reading one more message.
