Install the extension

Four steps, about two minutes. Everything happens on your own computer and you do not need to sign up anywhere else.

Works in Chrome, Edge, Brave, Arc and Opera, on Windows and Mac alike. Safari and Firefox cannot run it.

1
Download, then unzip
You must actually extract it: on Windows right-click the zip and choose Extract All, on a Mac double-click it. Opening the zip to look inside is not the same thing on Windows, that is only a preview. You end up with a folder of the same name. Keep it somewhere you will not delete by accident, such as Documents. You picked the right folder if manifest.json is sitting directly inside it.
2
Open your browser's extensions page
Type chrome://extensions in the address bar and press Enter. Turn on Developer mode, top right.
3
Load the folder
Click “Load unpacked”, top left, and pick the folder from step 1. The dialog shows folders only and will not show your zip: that is correct, it wants the folder. DanPicBook Listening Lab then appears in the list.
4
Paste your key
Open any YouTube video or dr.dk programme page, click the 🎧 button at the bottom right, paste your key, and choose your subtitle languages: one or two, changeable later from the panel.

Good to know

The dialog will not show my zip?: That is expected. Load unpacked is a folder picker, so archives are never listed. Extract the zip first, then select the folder that came out of it.
It says the manifest file is missing?: You selected one level too high. Go one folder deeper, until you can see manifest.json, and pick that folder.
Does it work on a Mac?: Yes, and the steps are identical. You do need Chrome or another Chromium browser (Edge, Brave, Arc, Opera). Safari uses a different extension format and cannot load it.
How do updates work?: We email you when there is a new build. Come back here, download the new zip, replace the old folder, and click the refresh icon on the card in chrome://extensions. Your key and your saved lines stay.
Chrome warns about developer-mode extensions?: That banner appears for every manually loaded extension. It is not an error. Dismiss it and carry on.
Clicked 🎧 and no subtitles?: The extension reads the Danish subtitles the player already has; it does not record audio. Switch the player's own subtitles on first (CC on YouTube, Undertekster on DR TV, Dansk on Netflix and the others) and they appear at once. A video with no Danish subtitle track cannot be subtitled; for podcasts, use the free library on the site.
