Building ConvoLens [1] - app to explore the content of video interviews from YouTube channels I like (such as Dwarkesh Patel's): research by keyword, RAG, visualization of discussed topics with a 2D projection, semantic graph, and the possibility to generate a new video or audio from a playlist of video segments.

Supports only YouTube as the data source, and Gemini 3.1 Flash Lite for processing, but it can easily be tweaked. Runs locally with Docker compose.
