Mochi - Making hard content enjoyable

Mochi is a Chrome extension that adapts web content for users with reading disabilities, ADHD, and dyslexia. Like its namesake, it makes hard-to-read content softer and more digestible.

Inspiration

Imagine trying to read a complex article when your brain processes text differently than others. For millions of people with reading disabilities, ADHD, and dyslexia, this isn't just an exercise - it's a daily challenge. Current accessibility tools either strip away content through summarization or offer basic font changes that barely scratch the surface of cognitive accessibility needs.

Enter Mochi - named after the soft, adaptable Japanese treat that makes hard things easier to digest. Just as mochi transforms rigid ingredients into something more approachable, our Chrome extension uses Built-in AI to make web content more accessible while preserving its full meaning and value.

What it does

Mochi revolutionizes cognitive accessibility by bringing AI-powered text adaptation right into your browser. Unlike traditional tools that summarize or simplify by removing content, Mochi maintains the complete reading experience while reducing cognitive load.

At its heart, Mochi uses Chrome's Built-in Gemini Nano AI to transform text in three thoughtfully designed ways:

  • "Simplify Complex Ideas" mode breaks down difficult concepts without losing depth
  • "Better Visual Organization" mode helps ADHD users maintain focus and attention
  • "Easier Reading Flow" mode makes text more predictable for dyslexic readers

Note: While these modes were designed for specific cognitive needs, we've consciously avoided labels in the interface to prevent stigmatization.

Each mode can be fine-tuned with three levels of adaptation (Low/Mid/High), complemented by research-based features like OpenDyslexic font support, cognitive-friendly color themes, and customizable text spacing.

Most importantly, because we use Chrome's Built-in AI, everything happens offline, right in your browser - ensuring both privacy and performance.

How I built it

The magic of Mochi lies in its sophisticated yet privacy-first architecture. By leveraging Chrome's Built-in Gemini Nano and Prompt API, we've created an intelligent system that:

  • Analyzes and chunks content for optimal processing
  • Applies disability-specific text adaptation strategies
  • Maintains the original meaning while reducing cognitive load
  • Works seamlessly across any website

Our development focused on two key principles: cognitive accessibility and user privacy. Every feature, from our content preservation algorithms to our quick-processing system, was built to support these goals.

Challenges and Breakthroughs

Building Mochi meant tackling both technical and accessibility challenges head-on. I needed to:

  • Fine-tune Gemini Nano for quick, accurate text processing
  • Develop strategies for handling diverse webpage structures
  • Balance simplification with content preservation
  • Create an interface that works for different cognitive needs

Through careful iteration and testing, I overcame these challenges while discovering innovative approaches to cognitive accessibility.

Impact and Future

Mochi represents more than just technical innovation - it's a step toward making the web truly accessible for everyone. As one of the first cognitive accessibility tools using Chrome's Built-in AI, we're demonstrating how local AI processing can transform user experiences while maintaining privacy.

Looking ahead, we're excited to expand Mochi's capabilities with:

  • Support for additional languages
  • Enhanced customization options
  • Educational institution partnerships
  • Collaboration with disability advocacy groups

Technical Innovation

Mochi showcases the power of Chrome's Built-in AI through:

  • Sophisticated text adaptation using the Prompt API
  • 100% offline, privacy-preserving processing
  • Cross-site compatibility
  • Intelligent content chunking and restructuring
  • Adaptive prompting based on user needs

By bringing together cognitive accessibility expertise and cutting-edge AI technology, Mochi creates a more inclusive web experience - one reader at a time.
