Inspiration

As a student, I often had to write separate prompts for simple tasks like summarizing notes or proofreading small paragraphs. Using ChatGPT or Gemini for these tasks was time-consuming, as long prompts were required even for basic study tasks.
I wanted a faster, one-click solution to handle common study tasks efficiently.

What it does

LazyGenie is an AI-powered Chrome Extension that lets students and professionals:

  • Summarize notes instantly
  • Proofread essays for grammar, spelling, and clarity
  • Translate content into multiple languages
  • Generate flashcards from any text
  • Analyze diagrams or handwritten notes using AI

All tasks can be done with a single click, without writing separate prompts every time.

How we built it

  • Leveraged Chrome’s built-in AI APIs (Prompt API) with Gemini API fallback for reliability
  • popup.js captures user input (text or images)
  • background.js routes requests to the appropriate API asynchronously
  • Multimodal inputs (text + images) are handled seamlessly, allowing diagram and note analysis.

Challenges we ran into

  • Ensuring seamless fallback from Prompt API to Gemini API
  • Handling multimodal inputs efficiently
  • Designing a simple, intuitive interface for multiple features
  • Managing API keys securely while keeping the demo ready for hackathon judges

Accomplishments that we're proud of

  • Built a fully functional, one-click AI study companion
  • Integrated multiple AI APIs with fallback logic
  • Developed multimodal analysis for images and handwritten notes
  • Designed a clean, user-friendly UI

What we learned

  • How to integrate and manage Chrome’s AI APIs effectively
  • Best practices for async API handling and error management
  • Importance of UI/UX for student-focused tools
  • How to structure an extension for scalability and modularity

What's next for LazyGenie: Your AI Study Sidekick

  • Implement secure API key management for production
  • Add more AI-powered study tools, like personalized summaries and quizzes.
  • Improve multimodal capabilities for larger documents and diagrams
  • Explore real-time collaboration features for study groups
