Learning Organizer - AI powered video learning platform

Learning Organizer is a full-stack MERN & Gemini API application that transforms YouTube videos into structured learning material.

Inspiration

Many learners open YouTube with the intent to study, but quickly get distracted by recommendations, shorts, and entertainment content. This leads to wasted time and fragmented learning. I wanted to solve this problem by creating a focused, structured learning environment around YouTube content.

What it does

Learning Organizer is a full-stack MERN application that converts YouTube videos into structured learning resources. It allows users to:

  • Organize videos into folders for different topics.
  • Take timestamp-based notes while watching.
  • Track learning progress.
  • Generate AI-powered summaries and quizzes for revision.

This transforms passive video consumption into active learning.

How I built it

Frontend: React (with drag-and-drop using DnDContext) Backend: Node.js + Express Database: MongoDB APIs Used: RapidAPI (for extracting video transcripts) Gemini API (for generating summaries and quizzes)

The workflow:

  1. Extract transcript from YouTube video.
  2. Process and send it to Gemini API.
  3. Generate structured summaries + quizzes.
  4. Store results using caching to avoid redundant API calls.

Challenges I ran into

  • Managing API rate limits (Gemini free tier) → solved using caching.
  • Extracting and syncing timestamp-based notes with video playback.
  • Designing smooth drag-and-drop folder/video organization.
  • Handling transcript inconsistencies from external APIs.

Accomplishments that we're proud of

  • Built timestamp-based note-taking synced with videos.
  • Implemented drag-and-drop organization for better UX.
  • Reduced API usage significantly using caching.
  • Enabled quick revision through AI summaries and quizzes.

What I learned

  • Integrating AI models into real-world applications.
  • Optimizing API usage with caching strategies.
  • Building interactive UI features like drag-and-drop.
  • Handling unstructured data like video transcripts.

What's next for Learning Organizer - AI powered video learning platform

  • Chrome Extension for one-click video saving.
  • AI-based video recommendations based on learning patterns.
  • Collaborative study groups.
  • Advanced analytics for tracking learning behavior.
