Inspiration

We noticed that students often struggle to review lectures efficiently. Recording and summarizing lectures manually is time-consuming, and important insights can get lost. We wanted to create a platform where students could record, organize, and summarize lectures quickly, making learning more efficient and engaging.

What it does

LecSum allows users to record lectures, store them in their personal library, rename or delete recordings, and view summaries of the audio content. Students can click on a recording to see detailed notes, enabling easier review and study.

How we built it

We built LecSum using Next.js, MongoDB, and Clerk for authentication. Audio files are stored in the /public/uploads folder, while metadata (name, date, user info) is stored in MongoDB. Key features like rename, delete, and summarize are handled through API routes that communicate seamlessly with the frontend. TailwindCSS was used for a clean, modern UI.

Challenges we ran into

Handling audio file storage and retrieval while keeping the database in sync was tricky. We also had to ensure real-time updates when a user renamed or deleted a recording. Making the summary feature reliable and responsive took significant backend optimization.

Accomplishments that we're proud of

We successfully built a fully functional lecture management platform with a polished UI. Users can record, rename, delete, and summarize lectures seamlessly. The system reliably stores and retrieves both audio files and metadata, providing a smooth experience.

What we learned

We deepened our understanding of Next.js API routes, MongoDB integration, and state management in React. We also learned the importance of UX design and real-time updates for creating interactive applications.
