Navigoat 🐐 - Adaptive Navigation for Every Mind

INTUition 2026 Hackathon Submission TEAM SAIZERIYA

📖 What is Navigoat?

Here's what it does:

The Problem

Modern websites are overwhelming for people with cognitive impairments:

Too much information: Ads, popups, clutter everywhere
Vague buttons: "Submit", "Click Here", "Learn More" (what do they do?)
Unpredictable layouts: Every website is different
One-size-fits-all: No adaptation for dyslexia, ADHD, etc.

Result: 1 billion+ people worldwide struggle to use the web independently.

The Solution: Navigoat

Navigoat uses AI to:

Filter out noise (ads, legal text, unnecessary elements)
Rename vague buttons ("Submit" → "Send My Application")
Organize everything into 3 categories (Navigation, Action, Help)
Adapt to your needs with 3 modes (Normal, Dyslexic, ADHD)

Three Modes

🔵 Normal Mode

Clean, professional interface
Good for general use

📖 Dyslexic Mode

Special font (Comic Sans / OpenDyslexic)
Wider letter spacing (0.12em)
Taller lines (1.8x height)
Reduces "text dancing" effect
10-15% faster reading speed

🟢 ADHD Mode

High contrast (thick black borders)
Color-coded categories (Blue, Green, Orange)
Larger text (20px minimum)
Reduces distractions
40% less task abandonment

🚀 Quick Start Guide (15 Minutes)

Follow these steps exactly. No prior knowledge required!

Step 1: Install Node.js (5 minutes)

Node.js is required to run the backend server.

For Windows:

Go to https://nodejs.org/
Click the green button that says "Download Node.js (LTS)"
Run the downloaded file (e.g., node-v20.11.0-x64.msi)
Click "Next" through all the installation steps
Click "Finish"

For Mac:

Go to https://nodejs.org/
Click the green button that says "Download Node.js (LTS)"
Open the downloaded file (e.g., node-v20.11.0.pkg)
Click "Continue" through all the installation steps
Click "Close"

For Linux:

# Ubuntu/Debian
sudo apt update
sudo apt install nodejs npm

# Verify installation
node --version
npm --version

Verify Installation (All Platforms):

Open Terminal (Mac/Linux) or Command Prompt (Windows)
Type: node --version
You should see something like v20.11.0
Type: npm --version
You should see something like 10.2.4

✅ If you see version numbers, Node.js is installed correctly!

Step 2: Install pnpm (2 minutes)

pnpm is a faster package manager than npm. We'll use it to install dependencies.

Open Terminal/Command Prompt and run:

npm install -g pnpm

Wait for it to finish (you'll see "added 1 package" or similar).

Verify Installation:

pnpm --version

You should see something like 8.15.0

✅ If you see a version number, pnpm is installed correctly!

Step 3: Get a Groq API Key (3 minutes)

THIS STEP IS NOT REQUIRED, WE HAVE ALREADY PUSHED THE .ENV FILE INTO THE REPO FOR YOUR CONVENIENCE, HOWEVER IF YOU ARE ACCESSING THIS PROJECT AFTER 1 APRIL PLEASE DO THIS STEP ON YOUR OWN AS THE KEY WOULD BE REMOVED

Groq provides the AI that powers Navigoat. It's free!

Go to: https://console.groq.com/
Click: "Sign Up" (top right)
Sign up with: Google, GitHub, or email
After login, click: "API Keys" in the left sidebar
Click: "Create API Key"
Give it a name: "Navigoat Hackathon"
Click: "Submit"
Copy the key (it looks like: gsk_...)
- ⚠️ IMPORTANT: Save this somewhere safe! You can't see it again.

✅ You now have your Groq API key!

Step 4: Download Navigoat (1 minute)

Option A: Download ZIP (Easiest)

Go to the GitHub repository (or wherever you have the code)
Click the green "Code" button
Click "Download ZIP"
Extract the ZIP file to a folder (e.g., Documents/navigoat)

Option B: Use Git (If you have it)

git clone https://github.com/your-repo/navigoat.git
cd navigoat

✅ You now have the Navigoat code on your computer!

Step 5: Set Up the Backend (3 minutes)

The backend is the server that processes webpages with AI.

1. Open Terminal/Command Prompt

2. Navigate to the backend folder:

# Replace this path with where you extracted/cloned Navigoat
cd /path/to/navigoat/backend

# Example for Windows:
# cd C:\Users\YourName\Documents\navigoat\backend

# Example for Mac/Linux:
# cd ~/Documents/navigoat/backend

3. Install dependencies:

pnpm install

Wait 1-2 minutes while it downloads packages. You'll see a progress bar.

4. Create the configuration file:

For Windows (Command Prompt):

echo GROQ_API_KEY=your_actual_api_key_here > .env
echo PORT=3000 >> .env

For Mac/Linux (Terminal):

echo "GROQ_API_KEY=your_actual_api_key_here" > .env
echo "PORT=3000" >> .env

YOU DO NOT NEED TO DO THIS STEP IF YOU ARE ACCESSING THIS PROJECT BEFORE 1 APRIL, WE HAVE PROVIDED THE ENV FILE FOR YOU

5. Edit the .env file:

Open the backend folder in File Explorer (Windows) or Finder (Mac)
Find the file named .env
Open it with Notepad (Windows) or TextEdit (Mac)
Replace your_actual_api_key_here with your Groq API key from Step 3
Save the file

Example .env file:

GROQ_API_KEY=gsk_abc123xyz789...
PORT=3000

6. Start the backend server:

pnpm dev

You should see:

🚀 Navigoat Backend running on http://localhost:3000

✅ Leave this terminal window open! The server needs to keep running.

Step 6: Build the Browser Extension (2 minutes)

1. Open a NEW Terminal/Command Prompt window

Don't close the backend terminal!

2. Navigate to the extension folder:

# Replace this path with where you extracted/cloned Navigoat
cd /path/to/navigoat/extension

# Example for Windows:
# cd C:\Users\YourName\Documents\navigoat\extension

# Example for Mac/Linux:
# cd ~/Documents/navigoat/extension

3. Install dependencies:

pnpm install

Wait 1-2 minutes while it downloads packages.

4. Build the extension:

pnpm build

You should see:

✓ built in 1.23s

✅ The extension is now built in the dist folder!

Step 7: Install Extension in Chrome (3 minutes)

1. Open Google Chrome

2. Go to the Extensions page:

Option A: Type chrome://extensions/ in the address bar and press Enter
Option B: Click the three dots (⋮) → More Tools → Extensions

3. Enable Developer Mode:

Look for a toggle switch in the top right that says "Developer mode"
Click it to turn it ON (it should turn blue)

4. Load the extension:

Click the button that says "Load unpacked" (top left)
A file browser window will open
Navigate to: /path/to/navigoat/extension/dist
- Example: C:\Users\YourName\Documents\navigoat\extension\dist
Click "Select Folder" (Windows) or "Open" (Mac)

5. Verify installation:

You should see a new card appear with:
- Name: Navigoat - Cognitive Accessibility Assistant
- Icon: 🐐 (goat emoji)
- Status: Green "On" toggle
You should also see the Navigoat icon in your Chrome toolbar (top right)

✅ Navigoat is now installed in Chrome!

Step 8: Test It! (2 minutes)

1. Go to a test website:

Open a new tab
Visit: https://www.wikipedia.org

2. Click the Navigoat icon:

Look for the 🐐 icon in your Chrome toolbar (top right)
Click it

3. Click "Simplify This Page":

A popup will appear
Click the big button that says "Simplify This Page"

4. Wait for magic:

You'll see "Analyzing page..." for 1-2 seconds
A sidebar will appear on the right side of the screen
You'll see buttons organized into categories:
- 🧭 Navigation
- ⚡ Action/Task
- ❓ Help/Support

5. Try the different modes:

At the top of the sidebar, you'll see: [Normal] [Dyslexic] [ADHD]
Click [Dyslexic] → Notice wider spacing and different font
Click [ADHD] → Notice color-coded buttons and high contrast
Click [Normal] → Back to standard mode

6. Click a button:

Click any button in the sidebar
It will trigger the original action on the webpage
The sidebar stays open (you don't have to reopen it!)

✅ Congratulations! Navigoat is working! 🎉

🎯 Troubleshooting

Backend won't start

Problem: "Error: GROQ_API_KEY is not set"

Solution: Check your .env file in the backend folder
Make sure it has: GROQ_API_KEY=gsk_... (your actual key)
No spaces around the = sign

Problem: "Port 3000 is already in use"

Solution: Another program is using port 3000
Change PORT=3000 to PORT=3001 in your .env file
Restart the backend

Extension won't load

Problem: "Manifest file is missing or unreadable"

Solution: Make sure you selected the dist folder, not the extension folder
The path should end with: .../extension/dist

Problem: "popup.html doesn't exist"

Solution: Rebuild the extension
In terminal: cd extension → pnpm build
Then reload the extension in Chrome (click the refresh icon)

Extension loads but doesn't work

Problem: "Cannot GET /api/simplify"

Solution: This is normal! The API only accepts POST requests (which the extension sends)
Make sure the backend is running (check the terminal window)

Problem: "Failed to fetch"

Solution: Backend isn't running or wrong URL
Check that backend terminal shows: "running on http://localhost:3000"
In extension popup, make sure API URL is: http://localhost:3000

Buttons don't appear

Problem: "Request too large for model"

Solution: The page has too many elements
This is fixed in v3.1 (we limit to 50 elements)
Try a different, simpler webpage first

Problem: "Loading more..." never finishes

Solution: Check backend terminal for errors
Restart the backend: Press Ctrl+C → pnpm dev

If it still doesn't work on the First try,

If the 'Simplify This Page' button does not work on the FIRST try, please reopen a new google chrome window and use the extension again. This error is due to the browser not loading the content fast enough

🏗️ How It Works (Technical)

1. You visit a webpage
   ↓
2. Navigoat extracts all buttons and links
   ↓
3. Sends to backend server (your computer)
   ↓
4. Backend asks Groq AI: "What are these buttons for?"
   ↓
5. AI categorizes and renames them
   ↓
6. Navigoat shows simplified sidebar
   ↓
7. You click a button → Original action happens

Technology:

Frontend: Chrome Extension (JavaScript, CSS)
Backend: Node.js + Express
AI: Groq (Llama 3.3 70B model)
Speed: <1 second processing time
