About langchain_yt_tools

Langchain_yt_tools is an open-source Python package providing two custom LangChain tools for searching and transcribing YouTube videos. CustomYTSearchTool retrieves the top video URLs for a given person's name, while CustomYTTranscribeTool downloads and transcribes those videos, outputting the text transcripts to a JSON file. The project includes a demo script that transcribes the top 3 results for a search query (e.g., 'Laszlo Bock') and requires YouTube API authentication on first use. Some functionality from this repository has been integrated into the main LangChain branch. Licensed under GPL-3.0 and built entirely in Python.
