Inclusive Web Reader - Making the Web Accessible for Everyone

The Problem We Solve

The web presents significant accessibility barriers for millions:

  • Long articles that are time-consuming to read
  • Foreign language content requiring translation
  • Complex technical text that's hard to understand
  • Privacy concerns with cloud-based AI tools
  • Internet dependency for accessibility features

Traditional tools require internet access, compromise privacy by sending data to servers, or lack the multimodal understanding needed for complex content.

Our Solution

Inclusive Web Reader is a Chrome extension leveraging Chrome's Built-in AI APIs to provide comprehensive web accessibility features—running entirely on-device. This ensures complete privacy (no data leaves your computer), offline functionality, and instant results.

Key Features

1. Content Summarization (Summarizer API)

Automatically condense long articles into concise bullet points

  • Click "Summarize Page" to extract key points from any webpage
  • Results appear in elegant floating overlays
  • Perfect for quick understanding of lengthy content
  • Ideal for users with limited time or attention challenges

2. Real-Time Translation (Translator API)

Translate selected text into 20+ languages with offline support

  • Spanish, French, German, Chinese, Japanese, Arabic, and more
  • Works completely offline after initial model download
  • No data sent to external servers - complete privacy
  • Perfect for language learners and non-native speakers

3. Text Simplification (Rewriter API)

Transform complex text into simpler, easier-to-understand language

  • Converts academic jargon to grade-school level vocabulary
  • Maintains original meaning while improving readability
  • Helps users with cognitive challenges or learning disabilities
  • Great for educational purposes and comprehension

4. Grammar Proofreading (Proofreader API)

Correct spelling, grammar, and punctuation errors in any text

  • Professional-grade corrections
  • Helpful for drafting responses or comments
  • Improves writing quality for non-native speakers
  • Instant feedback on grammar and spelling

5. Multimodal Image Analysis (Prompt API) - Coming Soon

Right-click images to receive AI-generated descriptions

  • Natural-language descriptions of images, charts, and diagrams
  • Alternative text generation for accessibility compliance
  • Helps visually impaired users understand visual content
  • Improves web accessibility and SEO

Chrome AI APIs Used

This extension showcases Chrome's Built-in AI capabilities by implementing FIVE different APIs:

  1. Summarizer API - Extracts key points from long-form content using type: 'key-points'
  2. Translator API - Cross-language translation with sourceLanguage and targetLanguage configuration
  3. Rewriter API - Text simplification with tone ('more-casual') and length ('shorter') parameters
  4. Proofreader API - Grammar correction with outputLanguage specification ('en')
  5. Prompt API (planned) - Multimodal image and chart analysis with image input support

All APIs run client-side using Gemini Nano, Google's on-device AI model, ensuring privacy and offline capability.

Technical Implementation

Architecture & Design

  • Manifest V3 Chrome Extension for modern security standards
  • Content Script injection for seamless page interaction
  • MAIN world script execution to properly access page-level AI APIs
  • Message passing between popup, content script, and page context
  • Chrome Storage API for user preferences (preferred language)
  • Floating UI overlays for non-intrusive result display

User Activation Handling

Chrome's AI APIs require user activation (gesture) for model creation. We implemented:

  • Authorization buttons injected into the page context
  • Click handlers that count as user gestures for create() calls
  • Progress monitoring for model downloads
  • Graceful error handling and user feedback

Privacy & Security Architecture

  • Zero server communication - all AI processing happens on-device
  • No data collection - user content never leaves their computer
  • Offline-capable - works without internet after initial model download
  • Open source - fully auditable codebase with MIT License
  • Transparent - users see download progress and understand data flow

Performance Optimization

  • First-time model download: 10-60 seconds (one-time per API, with progress indication)
  • Subsequent operations: Near-instant (<2 seconds)
  • Lightweight extension: ~400 lines of JavaScript
  • Minimal memory footprint: Models loaded on-demand
  • Efficient UI: Overlays created/destroyed as needed
