Youtube Video Summary

A small web app that provides a short summary of any YouTube video. The logic is the following:

1. Fetch captions from YouTube video
2. Ask ChatGPT to provide the summary of the video by provided captions

The results are cached (in-memory, expiration duration is configurable).
HTML page is embedded to the binary file, so the whole app is a single file

The service can be easily deployed to fly.io with flyctl deploy command. The app variable in fly.toml has to be updated accordingly There is a rate limiter (by default 3 requests per minute).
