The Cruxly Chrome Extension: Analysis Without a Tab Switch

Pasting a link into a separate tab isn't required anymore. The Cruxly Chrome extension adds a button right on the YouTube page and opens the analysis in a side panel, without leaving for cruxly.tech. It's available for Google Chrome only, for now.

The full guide to YouTube video analysis

How it works

On a YouTube video page or a PDF, the extension shows a toolbar badge and adds an "Analyze with Cruxly" option to the right-click menu. Clicking either one opens a side panel right over the page: the same analysis, the same chat grounded in the content, and the same transcript as on the site, with no new tab.

Same account, same quota

If you're already signed in on the site, the extension picks up the login automatically through the "Auto-detect" button in Settings, no separate sign-in. Analyses run through the extension count against the same quota as the site: there's no separate limit for the extension, the guest or plan quota is shared across both.

Works for PDFs too, not just YouTube

The button shows up for PDFs as well: on a page with an open PDF, or a link to one, on any site, not only YouTube. The format is detected automatically, no need to switch modes by hand.

How PDF analysis works

Recent analyses, one click away

The extension keeps a local list of recent analyses: title, source link, and time. That list lives in the browser, not on a server, and it's gone the moment the extension is uninstalled, along with the rest of its local settings.

The extension doesn't add capability beyond the site: same analysis, same chat, same quota. It removes one step, opening a tab and pasting a link, by putting a button where you're already reading or watching.
