🧠 CortexFlow— The Web That Adapts To Your Mind

🌟 Inspiration

The modern web delivers endless information — but it doesn’t understand the human behind the screen.
We wanted to build something different — a system that feels your focus, adapts to your cognitive rhythm, and transforms how the web communicates with the human mind.

That vision became CortexFlow — a browser intelligence that synchronizes with your attention and dynamically shapes content based on your mental state.

  • When your mind is tired, it simplifies.
  • When you’re focused, it deepens.
  • When curiosity rises, it expands.

CortexFlow bridges the gap between human cognition and digital experience.

🧩 What We Learned

Through building CortexFlow, we explored how Chrome’s built-in AI stack (Gemini Nano) can redefine the concept of adaptive web intelligence.
We combined prompt engineering, behavioral data, and cognitive modeling to design a privacy-first system that evolves with the user — locally, in real time.

To quantify mental effort, we developed a Cognitive Load Index (CLI):

CLI = (αS + βR + γM) / T

Where:

  • S = scroll frequency
  • R = reading rate
  • M = mouse micro-movements
  • T = active time window

This mathematical model drives how CortexFlow adjusts page complexity, tone, and depth dynamically — a personalized cognitive loop between user and web.

⚙️ How We Built It

CortexFlow was developed as a Chrome Extension (Manifest v3) using TypeScript, React, and IndexedDB, powered by Chrome’s built-in AI APIs:

  • Prompt API
  • Summarizer API
  • Rewriter API
  • Translator API
  • Proofreader API

🧠 Core Architecture

  1. Cognitive Tracking Layer — captures user behavior and calculates CLI in real time.
  2. AI Adaptation Engine — integrates Gemini Nano APIs to summarize, rewrite, or expand content inline.
  3. Inline Rendering System — performs non-destructive DOM updates for seamless adaptation.
  4. Privacy & Efficiency — processes entirely client-side; no cloud calls, no data collection.

⚔️ Challenges We Faced

Balancing privacy, intelligence, and speed was the hardest challenge.

  • Running multiple AI services locally without freezing the UI required asynchronous orchestration.
  • Designing a behavioral model that respects privacy while maintaining accuracy pushed us into creative problem-solving.
  • UX refinement took weeks — creating something that feels alive without being intrusive was a delicate balance.

True intelligence doesn’t overwhelm — it enhances and disappears into the flow.

🎯 Outcome

CortexFlow evolved into more than an extension — it’s a cognitive interface for the modern web.
It reads how you think, learns how you focus, and aligns the web experience to your state of mind.

  • When you’re in deep work, it provides clarity and context.
  • When you’re mentally drained, it simplifies and supports.
  • When curiosity strikes, it expands intelligently.
