Somewhere in the last two years, the median piece of content in a typical feed stopped being something a person made for another person. It became something a system produced or shaped to hold attention. The number gets argued about; the direction does not. Once a majority of inputs are optimized against you, intuition — which was trained on a human-made world — starts misfiring.

The cost is not just being fooled

The obvious harm is believing a fake. The quieter harm is the tax you pay staying alert: the low background hum of not knowing what is real, which is exhausting and which, over months, nudges people toward either gullibility or total cynicism. Both are wins for whoever is optimizing the feed.

A reality score, not a verdict

Defog does not tell you what to think. It gives you a weekly exposure score — a single number from 0 to 1000 that estimates how synthetic and how manipulative your week's inputs were — and an inline lens that marks individual items. Over time the score does something subtle and useful: it turns an invisible environmental condition into something you can actually notice and adjust.

We built this for individuals first because the market never will. The business model of the open web is attention, and attention is cheapest to capture when you cannot tell what you are looking at. A tool that restores that signal has to be funded by the people it protects, not by the people buying their attention. That is why Fluidity's free tier is a real product, not bait.
