The Askube Chrome extension adds a sidebar directly on YouTube. Summarize, transcribe, and generate Twitter threads, LinkedIn posts, and flashcards — all without switching tabs.
The friction is the tab switch. Copy the URL. Open a new tab. Paste it. Wait. Switch back. By the time you have the summary, you've already lost your place in the video.
The extension puts everything in the sidebar, right where you're already watching.
Install once, use on every YouTube video.
Add the Askube extension from the Chrome Web Store — takes 30 seconds.
Navigate to any YouTube video. The Askube sidebar icon appears in your toolbar.
Click the icon to open the sidebar. Summarize, extract the transcript, or generate social content without leaving the tab.
Full access to the Askube content engine — no tab switching required.
A full Askube panel appears alongside any YouTube video — no new tab, no copy-pasting URLs.
