Power Presenter

Bringing static powerpoints into the modern age, with real-time collaboration and AI integration.

Comment

Inspiration

We've sat through a ton of boring presentations with monotonous lecturers, and had enough. In the big '25, when we have real-time collaboration, AI integration, and automatic note taking at our fingertips, it's crazy that we still have static powerpoint slides as the de-facto standard.

What it does

Power Presenter takes a laundry list of friction points when it comes to lectures and conglomerates their solutions into an all-in-one solution. Just upload your slide deck and Power Presenter will do the rest.

For the audience:

  • No need to download your professor's slide deck. View it simply in-house to follow along with your professor.
  • Submit real-time questions regarding a specific line of work, a given topic, or the whole presentation. View and upvote other questions from other students to raise better questions to the top.
  • Professor neglected to write something down in the notes? No problem. Peruse a AI-generated annotated slide deck that contains the key points that your professor mentioned in class, even if you slept in.
  • Need to leave soon? Professor tends to go over time? Not a problem. Power Presenter predicts how long the presentation will take, based on their current rate. You can now leave when you need to, and know how much more there is to cover.

For the professor:

  • Tough crowd? No one is responding? No problem. Receive real-time AI-powered actionable feedback that tells you exactly what slides you need to go over again and what concepts are not quite sticking with your audience.
  • Gather simple audience demographic information to learn about your retention over time.
  • Automatically record your lecture for record-keeping later, with just your phone.

How we built it

We used NextJS for the frontend, NodeJS for the backend socket server, Firebase for account authorization and presentation storage, and Assembly AI for live vocal transcription.

Challenges we ran into

Connecting to the live web socket for Assembly was harder than expected. We almost had to scrap that feature, thinking that it wasn't possible on web.

Accomplishments that we're proud of

We're happy to implement the question/answer system, something we've been dying to have in a real lecture environment.

What we learned

We learned to get more sleep before a hackathon.

What's next for Power Presenter

We hope to test our product with key professors to not only to stress test our product against a large concurrent load, but to also gather customer feedback from both our professors and students.
