What is comment-finder-for-youtube?

Comment Finder for YouTube is a browser extension that solves a simple but annoying gap in YouTube itself: there is no way to search through the comments on a video, Short, or channel to find a specific one. This extension adds that search box. You open it from either a small popup in your browser toolbar or a side panel next to the video, type in what you are looking for, and it searches the comments and their replies on whatever YouTube page you currently have open. Search results come back up to one hundred at a time, with more loading automatically as you scroll further, and each result is a clickable link that jumps straight to that comment and its timestamp in the video. The toolbar icon changes color to show at a glance whether the page you are currently on is searchable, and the extension keeps track of your last search so it reappears if you close and reopen the popup or side panel. It works on regular videos, YouTube Shorts, and channel pages alike. Under the hood, the extension pulls comment data through YouTube's own official Data API rather than scraping or injecting anything into the page, and the README notes it asks for only minimal browser permissions. The published, ready to install version is available directly from the Chrome Web Store for anyone who just wants to use it. For people who want to build it themselves from source, the README explains the process involves the Bun JavaScript runtime, a Cloudflare account to run a small proxy server that holds the YouTube API key, and a Google API key of your own restricted to the YouTube Data API. This setup exists so the extension itself never has to embed a private API key directly inside it. No license is stated in the README.
