How it works

Three simple steps, completely automatic

01

You click a link in Slack

Any link in any Slack workspace — messages, channels, threads, or DMs.

02

AlterEgo detects the workspace

It knows exactly which workspace you're in when you click.

03

Opens in the right profile

The link launches in your mapped browser profile automatically.

Built for power users

Minimal footprint, maximum utility

Invisible by design

No Dock icon. No menu bar item. AlterEgo runs silently in the background — you'll forget it's there.

Instant detection

Detects workspace switches in real-time. Links route correctly every time.

Configure once

Map workspace names to browser profiles in a simple config file. Edit once, then never touch it again.

Privacy-first

No analytics, no telemetry, no network requests. Your browsing habits stay on your machine.

Stop switching profiles manually

Download AlterEgo and let your links find their way home.
