User Agency on Programmer.ie: Modern AI programming

The Browser as a Personal Policy Engine

Wed, 02 Sep 2026 18:15:00 +0100

So far, the browser has supplied models, sessions, context and tools. We used them to inspect applications and constrain agent actions.

There is another direction the same architecture can travel.

Instead of asking only, “What can an agent do to a website?”, ask:

What should the website be allowed to do to the user’s attention?

A personal policy engine observes the page, evaluates content under rules chosen by the user and changes presentation locally. It is not the site’s moderation system. It is the user’s mediation layer.

The User, Not the Platform, Controls the Interface

A platform decides what enters a feed, how it is ranked, which controls are prominent and which forms of automation are available.

The user may select among the settings the platform offers. That is not the same as controlling the interface.

Browser AI creates the possibility of another layer: software acting locally, under rules the user can inspect, across sites and independently of one model provider.

This chapter assembles the system we have built and defines the limits of that claim.
