MirrorMask

Every platform builds a profile of who you are. Google, Facebook, Reddit, Amazon. They all decide what you're interested in, then feed you content and ads based on that identity. You never chose it, you can't edit it, and it follows you everywhere. I wanted something that didn't just add privacy, I wanted to rewrite what is reflected back. MirrorMask is a native Mac app that shows you the interest profile Google has built about you, then actively reshapes it. You pick a persona (a fisherman, a home chef, a tech enthusiast) and MirrorMask browses as that person across Google, YouTube, Facebook, Reddit, Amazon, and Temu. Real Chrome sessions, real browsing activity. The algorithms genuinely update what they think you care about. It's not ad blocking. It's not a VPN. Those are defensive. This is the opposite. You choose what the machines see. You can watch it work. Before/after profile snapshots show interests appearing and disappearing. Schedule it to run at 2am while you sleep. Wake up as someone the algorithms don't recognize. Everything runs locally on your Mac and helps you escape your algorithmic bubble and even curate it so that you see other parts of the web or topics you wouldn't have discovered otherwise.
