Your attention, measured.

How it works

📏

Measure

Five information-theoretic entropy metrics run silently in your browser, quantifying the information density, flow rate, and navigation randomness of your browsing.

📊

Visualize

A floating overlay shows your real-time entropy thermometer. A timeline chart reveals when and how your attention drifts from focus to noise.

🎯

Optimize

Set your daily anchor. Get gentle alerts when your distraction index stays high. Review patterns. Inject negentropy back into your system.

Five entropy metrics

Htext — Content Entropy

H = −Σ pi log₂ pi

Shannon entropy of page text word frequencies. High-entropy pages have unpredictable, fragmented content.

R — Information Flow Rate

R = ΔH / Δt

Rate of new content emergence. Short video feeds have extremely high R; deep articles have near-zero R.

Hrate — Transition Entropy

H = −Σ πi Pij log₂ Pij

Markov chain entropy rate of your navigation sequence. Random jumping between sites = high entropy rate.

G — Goal Relevance

G ∈ [0, 1]

How related is the current page to your daily anchor? High G means even high-entropy pages are productive.

D — Distraction Index

D = Hrate × (1 − G) × f(switches)

The composite metric. Combines navigation randomness, goal irrelevance, and tab-switching frequency into a single real-time distraction score.

"Life feeds on negative entropy."

— Erwin Schrödinger, "What is Life?" (1944)

Your attention is a thermodynamic system. Focus is low entropy — ordered, predictable, goal-directed. Mind-wandering is high entropy — disordered, random, dissipative. Negentropy gives you the instruments to measure and manage this process.

🔒 100% Local. Zero tracking.

All computation happens in your browser. No cloud, no sync, no analytics, no external API calls. Your entropy data never leaves your device.
