MirrorMask scrapes your real Google ad profile, then reshapes it by browsing as a different persona. Automatically, every night. Break your filter bubble while you sleep.
How it works
MirrorMask opens your real Chrome and browses as a completely different person. Google searches, YouTube videos, Facebook pages, Reddit threads. All as your chosen persona, automatically.
No passwords needed
Uses your existing Chrome session. Never asks for credentials.
Safe for your accounts
Just searches and video views. No posting or profile changes.
100% on your Mac
All data stays local. No cloud, no analytics.
Why MirrorMask
Whether you want to disappear from trackers or reshape what they show you, MirrorMask gives you control.
For Privacy
Advertisers are building a model of your life so they can sell you things and sell that model to others. MirrorMask buries your real data under layers of noise, making their profile of you useless.
For Curation
Tired of the same recommendations? MirrorMask lets you intentionally train the algorithms. See content from perspectives you choose, not ones chosen for you.
Baseline Capture
MirrorMask scrapes your real Google ad profile. Every interest, every demographic, every signal. See the version of you that advertisers built, then watch it dissolve.
Personas
Each persona is a fully realized digital identity, complete with search queries, YouTube interests, websites, Facebook pages, Reddit subreddits, and shopping signals.
Daily Automation
Set a daily schedule and forget about it. MirrorMask opens Chrome at 2 AM, performs searches, watches YouTube, visits websites. All as your chosen persona.
Insights
See exactly how much of your digital identity has changed. MirrorMask tracks new interests appearing, old ones displaced, and the percentage reshaped.
The Proof
We ran a controlled experiment: three fresh Google accounts on isolated US residential proxies. Two browsed with personas. One did nothing. Here's what happened to their ad profiles.
Meet the personas
Every persona comes with search queries, YouTube interests, websites, Facebook pages, Reddit subs, and shopping signals. Or create a custom one from scratch.

FAQ
You should be skeptical about anything that touches your browsing data.
It's the idea that you should have a say in how algorithms see you. Right now, platforms build a profile of your interests and behavior, then use it to decide what you see. MirrorMask lets you actively reshape that profile instead of just accepting whatever they've decided you are.
It's how platforms like Google, YouTube, and Facebook decide what content to show you based on what they think you're interested in. MirrorMask changes the signals those algorithms rely on, so you get to influence what shows up in your feeds instead of leaving it entirely up to them.
MirrorMask runs entirely on your Mac. All browsing data (your baseline profile, browsing history, and persona activity) stays on your machine. The only server communication is license key activation. No analytics, no telemetry, no tracking.
MirrorMask uses your real Chrome browser and browses websites normally, the same way you would. It performs Google searches, watches YouTube videos, and visits websites. There's nothing that distinguishes this activity from regular browsing.
Ad platforms build your profile based on what you search, watch, and visit. MirrorMask does those things as someone else: a Fisherman, an Investor, a Pet Lover. Over time, the algorithms update their model of you to reflect the persona's interests.
Your Mac needs to be awake for MirrorMask to run. If your Mac is asleep at the scheduled time, MirrorMask will run the session when it next wakes up.

Yes, MirrorMask currently requires Google Chrome. Chrome is the primary target because Google's ad ecosystem is the most pervasive and responsive to browsing behavior changes.
