People underestimate how much AI privacy is really a context-preservation problem.

Anyone can protect a prompt by deleting half of it.
the hard part is removing identity without changing the reasoning task.

AgentCloak launched to solve that problem in the browser.

It sits in the browser, replaces sensitive values with realistic stand-ins before the prompt leaves your machine, then puts the original values back into the response locally.

This isn't just redaction. Redaction removes information and changes the task. The harder problem is preserving enough semantics for the model to answer properly while removing the pieces that identify you.
