reeLm is a Chrome extension that saves YouTube videos you bookmark with Shift+Y and indexes their auto-generated transcripts so you can search across them later.
When you press Shift+Y on a YouTube video, reeLm sends the video’s URL, title, and current playback timestamp to a local server running on your own computer at http://127.0.0.1:7799. That server then fetches the video’s auto-generated transcript from YouTube and stores it in a local SQLite database on your computer.
Nowhere except your own computer. Specifically:
~/Library/Application Support/Reelm/videos.db (macOS)$(brew --prefix)/var/log/reelm/ (when installed via Homebrew)No data is sent to reeLm’s developer, to any analytics service, or to any third-party server. There is no telemetry, no account system, no cloud sync, and no advertising.
reeLm makes network requests to two destinations only:
127.0.0.1:7799 — the local server bundled with reeLm, running on your own machine.youtube.com — to fetch transcripts via yt-dlp for videos you’ve explicitly saved.Stop the server and remove the database:
brew services stop reelm
brew uninstall reelm
rm -rf ~/Library/Application\ Support/Reelm
Or simply delete ~/Library/Application Support/Reelm/videos.db to wipe your saved-video index while keeping the extension installed.
