Hello, fatbrowser

What fatbrowser is

fatbrowser is a browser extension for Chrome and Edge that tracks your browsing patterns — focus streaks, context switches, time on feeds — and turns them into a simple daily picture of how you spent your attention.

It comes with a web dashboard where you can see today's focus score, review your history, and spot patterns over time. There's also a team mode for workplaces that want aggregate focus data without surveillance.

What it actually tracks

fatbrowser measures a few specific things:

• Focus Score — a percentage based on how much of your active time was spent on sites you consider productive, adjusted for how often you switched between contexts.
• Focus Time — total minutes of sustained work without frequent tab-switching.
• Distractions — each time you switch from a focused context to something else and back.
• Best Streak — your longest uninterrupted focused period in a day.
• Feeds Avoided — how many times Minimal Mode hid an algorithmic feed (YouTube home, Twitter timeline) before you could scroll.

It does not record URLs, page content, screenshots, or keystrokes. The extension watches patterns, not specifics.

Minimal Mode

Minimal Mode is an optional feature that hides algorithmic feeds on YouTube and Twitter. When you visit youtube.com, for example, the home feed is replaced with a blank page. You can still search and watch specific videos — you just won't get pulled into the recommendation engine.

Each time a feed gets hidden, fatbrowser logs it. Over time you can see in your dashboard whether avoiding feeds actually correlates with better focus scores for you personally.

The dashboard

The web dashboard at fatbrowser.com shows your data across three views:

• Today (Free) — your current focus score, focus time, distraction count, and feeds avoided.
• History (Pro) — a 30-day grid of your focus data, day by day.
• Insights (Pro) — your best focus hours, averages, and whether feed avoidance is actually helping.

Teams

The Team plan lets a group share aggregate focus data. Managers see team-level trends — average focus scores, total feeds avoided — but never individual browsing details. The idea is that a team can work on focus together without anyone feeling watched.

Privacy

Tracking happens in the browser extension. Only aggregated daily summaries are sent to your account. No raw browsing data leaves your machine. Team admins see team-wide numbers, not per-person browsing activity. This is core to how fatbrowser works, not an afterthought.

Pricing

Three tiers: Free ($0), Pro ($0.99/mo), and Team ($1.99/mo per member). Free gives you today's metrics and Minimal Mode. Pro adds historical data and insights. Team adds shared analytics and member management.

Getting started
