Introduction

In this article, we will explore a project called "Youtube Summarizer" created by Aryan. The Youtube Summarizer is a Chrome extension that allows users to summarize any YouTube video in just a few lines. This article will provide a detailed explanation of the project's functionality and structure, as well as instructions on how to install and use the extension.

What is Youtube Summarizer?

The Youtube Summarizer is a Chrome extension developed by Aryan. It offers users the ability to summarize YouTube videos quickly and efficiently. By utilizing this extension, users can avoid watching entire videos and instead obtain concise summaries in just a few lines. This feature can save users a significant amount of time and streamline their video consumption experience.

How does Youtube Summarizer work?

The Youtube Summarizer extension is built upon an API created using Flask in Python. This API relies on several technologies and libraries, including the Hugging Face Transformers library for pre-trained models and the YouTube Transcript API for extracting video transcripts. The extension interacts with the API by sending a URL request, and in response, it receives a summarized version of the video's transcript. The extension then displays this summary to the user.

The Structure of the Project

The project consists of two main components: the API and the Chrome extension. The API, which is implemented in Python using the Flask library, handles the process of summarizing YouTube videos. The Chrome extension, built with HTML, CSS, and JavaScript, interacts with the API to request and display the summarized video transcripts. The project's structure and functionality will be further explored in the following sections.

API - app.py

The app.py file acts as the API for the Youtube Summarizer project. It handles the process of summarizing YouTube video transcripts. The API is structured as follows:

Initialize Flask App

The Flask app is initialized using the flask library, which is a popular Python library for creating APIs, websites, and web apps.

Summary API

The main functionality of the API is the /summary API endpoint. This endpoint takes a YouTube video URL as an argument and returns the summarized transcript of the video. The API utilizes the YouTube Transcript API to retrieve the video transcript and the Hugging Face Transformers library for the summarization model.

Get Transcript Function

The get_transcript function is responsible for extracting the video transcript from a YouTube video given its URL. This function utilizes the YouTube Transcript API to retrieve the transcript in the form of a list of subparts.

Get Summary Function

The get_summary function takes the video transcript as input and utilizes the Hugging Face Transformers library to summarize the text. Since the summarization model has a limitation that it can only handle up to 1000 characters at a time, the text is divided into multiple parts for summarization, and the results are combined to Create the final summary.

Chrome Extension

The Chrome extension is responsible for user interaction and displaying the summarized transcripts. Here are the main components of the extension:

manifest.json

The manifest.json file is required by Chrome and provides essential information about the extension. It includes details such as the extension's title, description, permissions, and other settings.

popup.html

The popup.html file defines the layout and design of the extension. It contains elements such as the extension's title, a summarize button, and a Paragraph for displaying the summarized output.

popup.js

The popup.js file contains the logic of the extension. It handles button clicks, retrieves the URL of the currently active YouTube video using the Chrome API, sends a request to the API for summarization, and displays the summarized output in the extension's popup window.

How to Install and Use the Youtube Summarizer Extension

To install and use the Youtube Summarizer extension, follow these steps:

1. Enable developer mode in the Chrome extensions settings.
2. Load the unpacked extension by selecting the extension folder from your project directory.
3. Open a YouTube video in Chrome.
4. Click on the Youtube Summarizer extension icon in the browser toolbar.
5. Click the "Summarize" button in the extension's popup window.
6. The extension will retrieve the video's URL, send a request to the API, and display the summarized transcript in the extension's popup window.

Conclusion

The Youtube Summarizer project by Aryan provides a convenient way to summarize YouTube videos. By utilizing the Chrome extension and the API, users can save time by obtaining concise summaries instead of watching full videos. This article has explored the functionality of the project, including the API structure and the Chrome extension's components. By following the provided instructions, users can easily install and utilize the Youtube Summarizer extension. Start summarizing YouTube videos efficiently with this powerful tool.
