hiteshkoli0310/Review-radar ? reverse-engineered prompt

Build me a Python app called ReviewRadar that lets someone type in a product name and instantly see what people think of it based on YouTube review comments. It should search YouTube for relevant review videos, pull in the video details and comments, clean up the text, and classify the comments as positive, neutral, or negative. I want a simple dashboard where I can see an overall summary, the sentiment breakdown, some example comments, and a few basic charts so the results are easy to understand.

It would be great if the app also shows a comparison against a couple of simpler sentiment methods, and highlights any competitor products people mention in the comments. If there are cached results or existing insights, use those so the dashboard loads fast. Please make it easy to run locally with one command, and if you need to check current docs for anything, go ahead and look them up online.
