From the video you are watching
Use Companion to read supported captions or follow the offered audio workflow. When recording playback, keep the video playing until capture finishes. The extension keeps processing when you close its popup.
Connect to the right destination
Open Companion from the Chrome toolbar and choose Web workspace. Sign in and connect the same Vizmemo account. Choose Desktop Power Mode only when you intend to use the local application.
Install the current extension
Download the ZIP, extract it into a stable folder, open chrome://extensions, enable Developer mode, and choose Load unpacked. Select the extracted extension folder containing manifest.json. Keep the folder in place.
Update an unpacked extension
Extract a new version into its own stable folder. In chrome://extensions, remove the old unpacked entry and load the new folder, or use Reload if you intentionally updated the same folder. Reconnect if asked, then refresh the video page.
