Brevity

💡 Inspiration💡

In 2022, video-based content is more prevalent than ever before. However, what’s also more commonplace is how busy people’s lives are in modern times. This is why we built Brevity, the only AI-powered browser extension that summarizes videos in a way that’s meaningful to you.

✨ What It Does ✨

All the user needs to do is click the extension over the desired video and request to “make it brief”; then they can read a succinct summary of the video. Brevity does this by first retrieving the audio from Youtube and uploading it to the AssemblyAI server. This will then return a transcript in the form of chapters which get subsequently uploaded to CoHere.ai to be converted into smart bullet points.

But that’s not all. What if the user didn’t find the needed information in the summary? Well, they can ask their questions to Brevity themselves. Brevity can handle any questions from basic content to abstract concepts by communicating with OpenAi’s GPT-3 API to develop an answer.

⚙️ How We Built It ⚙️

We use typescript with tRPC to create a type-safe environment for robust code.
Use assemblyAI to transcribe the video into text and generate chapter summaries.
Use Cohere.ai to generate bullet points from the chapter summaries.
Use GPT-3 to answer the user's questions based on the transcript.
Cache all the data locally to save on resources.
Built a front-end chrome extension with React to make it friendly and easy to use.

🔥 Challenges We Ran Into 🔥

Creating robust prompts which give stable and high-quality results for Cohere.ai.
Making an AI compatible with long input transcripts.
Creating a chrome extension with React.
Integrating complex AI models into our program.

🏆 Accomplishments We're Proud Of 🏆

The product is functional and is surprisingly useful in our own lives.
First time designing such an intuitive and aesthetic user interface.

📈 What's Next For Brevity 📈

Though we’re very proud of Brevity’s functionality on YouTube, we recognize that its concept may be better applied in the world of academia. That’s why we’d like to expand it to other video platforms in the future, as well as adding a feature to tailor the complexity of the summaries.
