Lecture Summarizer

This Python application uses the AssemblyAI API to automatically summarize virtual lectures and answer questions about the lesson material. It's built with Streamlit and AssemblyAI's Python SDK.

Features

• Automatic Lecture Summarization: The application transcribes and summarizes lectures from local files, remote files, or YouTube videos using AssemblyAI's LeMUR API.
• Question-Answering: Users can ask questions about the summarized lecture. The answers are generated using AssemblyAI's API.
• Interactive UI: The application features an interactive interface created with Streamlit. Users can input their AssemblyAI API key, choose the type of file, and ask questions about the lecture.

Use Cases

• Online Learning: Students can use this application to summarize and ask questions about online lectures.
• Research: Researchers can use this to understand lectures or talks related to their field of study.
• Professional Development: Professionals can use this to understand webinars, online courses, or other educational content.

Getting Started

You need to have an AssemblyAI API key. If you don't have one, you can get it from the AssemblyAI Dashboard. You can either paste your API key in the application's text box or set it as an environment variable (ASSEMBLYAI_API_KEY).

How to Use

1. Enter API Key: Paste your AssemblyAI API key in the text box or set it as an environment variable.
2. Choose File Type: Select the type of file you want to summarize - a local file, a remote file, or a YouTube link.
3. Upload/Enter File: Depending on the chosen file type, upload a local file, enter a public link to a remote file, or enter a YouTube link.
4. Enter Context (Optional): Enter contextualizing information about the file, if needed.
5. Submit: Click the "Submit" button to start the summarization process. The application will transcribe the file, generate a summary, and display it.
6. Ask Questions: After the summary is displayed, ask questions about the lecture. Enter your question in the text box and click the "Submit" button to get the answer.

Note

Processing a file takes approximately 15-30% of the file's duration. If a YouTube link is used, additional time will be needed to extract the file.
