YouTube-Transcript-Summarizer

Youtube Transcript Summarizer is a Chrome Extension that allows users to get a summarized version of the transcripts of YouTube videos with a single click. It utilizes Natural Language Processing (NLP) algorithms such as Latent Semantic Analysis (LSA) and state-of-the-art Huggingface Transformer models to efficiently summarize the transcripts of YouTube videos with a single click. It is built on a Flask Backend REST API to expose the summarization service to the client.

Project Stages

Features

• Summarizes YouTube video transcripts employing advanced NLP techniques.
• Utilizes Latent Semantic Analysis (LSA) for extractive summarization of very long transcripts.
• Leverages Transformer models for abstractive summarization of shorter transcripts.
• Allows the user to adjust the maximum length of the summarized text through dynamic truncation.
• Adopts a language-agnostic approach and supports transcript summarization even for videos without subtitles.
• Employs an asynchronous XMLHttpRequest to ensure non-blocking communication with the Flask Backend.
