Thread Summarizer

We read it so you don't have to

Comment

Inspiration

Online platforms like Reddit and discussion forums contain valuable information, but long threads with hundreds of comments make it difficult and time-consuming to find clear answers. We wanted to build a tool that helps users quickly understand the core discussion without reading everything, while still allowing them to ask follow-up questions for deeper clarity.

What it does

Thread Summarizer takes a URL of a Reddit post or any discussion thread, analyzes the entire conversation, and generates a clear and concise summary highlighting:

  • Main points
  • Key opinions
  • Common conclusions

Users can also ask follow-up questions to get specific answers based only on the thread content, making it interactive and easy to understand even complex discussions.

How we built it

  1. Extract text content from the given thread URL
  2. Clean and preprocess posts and comments
  3. Use an AI model to summarize the discussion into key points
  4. Add a question-answering layer for follow-up queries
  5. Design the system to be simple and beginner-friendly

Challenges we ran into

  • Handling very long threads with mixed opinions
  • Removing irrelevant or repeated comments
  • Making summaries short but still meaningful
  • Ensuring follow-up answers stay accurate and grounded in the thread
  • Working with limited time and resources as beginners

Accomplishments that we're proud of

  • Successfully summarizing long and complex discussion threads
  • Producing summaries that are clear, readable, and useful
  • Implementing an interactive follow-up question feature
  • Completing a functional project within hackathon time
  • Building confidence and teamwork skills

What we learned

  • How to process and clean large text datasets
  • How AI can simplify real-world information overload
  • The importance of defining the problem clearly
  • Team collaboration and debugging under time pressure
  • How to present a project effectively in a hackathon

What’s next for Thread Summarizer

  • Support for more platforms (Quora, Stack Overflow, Discord threads)
  • Chrome Extension: Right-click any Reddit thread → “Summarize This”
  • Sentiment Analysis: Detect whether a thread is mostly positive, negative, or mixed
  • Expert Detection: Highlight comments from verified experts or moderators
  • Related Threads: Suggest similar helpful discussions ("People also found useful")
