🧠 Inspiration

In today’s fast-paced world — whether you’re a student, a researcher, a professional, or an entrepreneur — PDFs dominate how we access knowledge. But these documents are often long, dense, and time-consuming to process.

The idea for EduSummarize came from real-life needs:

  • 📚 Students trying to catch up on lectures
  • 💼 Professionals needing to digest reports
  • 🚀 Entrepreneurs analyzing research or pitch decks
  • 👩‍💻 Career builders seeking to understand learning material quickly

I saw a gap: What if we could instantly summarize any PDF into 3 styles — short, medium, or detailed — and hear it aloud, with or without logging in? That’s where EduSummarize was born — combining AI summarization, voice synthesis, and a beautiful, accessible UI.


🚀 What it does

EduSummarize is a voice-powered, AI-enhanced educational tool that turns any uploaded PDF into intelligent, listenable summaries.

Core Capabilities:

  • 📄 PDF Upload & Extraction – Drag-and-drop or browse to upload PDFs, auto-extract content
  • ✂️ Three Summary Modes – Choose between:

    • Short (1–2 sentences)
    • Medium (paragraph)
    • Detailed (sectional breakdown)
  • 🧠 AI Summarization – GPT-4o creates rich, accurate summaries based on selected mode

  • 🔊 Audio Narration – Hear summaries using ElevenLabs’ natural-sounding AI voice

  • 🔓 Login Optional – Works with or without signing in

  • 💰 RevenueCat Integration – Paywall for premium voice features

  • 🛍️ Science Store – Browse and buy educational kits

  • 🏷️ Bolt Badge – Proudly built for the Bolt Hackathon, badge on homepage


🛠️ How we built it

Frontend:

  • React 18 + TypeScript (Vite-based)
  • Tailwind CSS for clean, responsive UI
  • Framer Motion for animations
  • React Router for navigation

AI Services:

  • Azure OpenAI (GPT-4o) for multi-tiered summarization
  • ElevenLabs for speech generation (Rachel’s voice)

Backend & Services:

  • Supabase for authentication and user data
  • RevenueCat for managing subscriptions
  • PDF.js for extracting text from uploaded documents

Deployment:

  • Hosted via Netlify with continuous deployment

🧗 Challenges we ran into

  • 📄 Large File Handling: Some PDFs had mixed formats, non-selectable text, or massive page counts. We implemented dynamic chunking and error handling.
  • 🧠 Prompt Engineering: Tuning GPT-4o prompts for different summary lengths without losing context was tricky — we had to test many formats to balance brevity with accuracy.
  • 🔊 Voice API Limitations: Managing API load and ensuring voice synthesis didn’t lag across browsers and devices took iteration.
  • 🧪 Smooth UX Flow: Ensuring users could move from upload → summary → voice without friction required thoughtful state management.
  • 🔐 Auth vs. No Auth: Letting users access basic features without logging in while still enforcing premium logic with RevenueCat involved edge-case handling.

🏅 Accomplishments that we're proud of

  • ✅ Created an AI-powered tool that anyone — from a high schooler to a CEO — can use effortlessly
  • 🧠 Implemented 3-tier summaries for different learning and comprehension needs
  • 🎧 Delivered smooth voice output with natural tone and downloadable audio
  • 🎨 Designed a polished, premium-grade UI with Bolt's spirit of speed and innovation
  • 🌍 Made it inclusive: works with or without login, available on any device
  • 💰 Connected learning to monetization using RevenueCat + a Science Store

📚 What we learned

  • 🔧 How to build AI-first UX: Letting the AI feel like a feature, not a barrier
