This is a tool designed to search for specific sentences in a YouTube channel's caption text, it supports case sensitive and insensitive matching, string matching or ECMAScript regular expressions, all languages officially supported by YouTube's creator interface and has a user-selectable limit to the number of videos crawled.
YouTube caption search simply searches publicly available data that any user could access via the YouTube frontend's view transcript, it will not work on unlisted and especially not on private videos.
I am not responsible for any end a user chooses to use this tool for as that is solely up to the user's discretion.
This frontend was made using the Svelte framework and the Vite build system, to do changes to the tool, you'll need node.js and the packages listed in the package.json. If you intend to submit changes upstream that include modified package versions, please use pnpm as your package manager instead of npm in order to keep dependency locking consistent.
This project uses the piped API, a privacy focused wrapper for the YouTube API to gather channel, video and subtitle info.
