• Reload the YouTube tab. Pages that were already open when you installed or updated Insightube need one refresh.
• Open a video page (the address starts with youtube.com/watch). The panel shows beside the video, above the recommendations.
• If the panel is there but folded up, click its title bar to open it. You can make it open by itself in Settings → Open the panel automatically.

Insightube reads YouTube's own captions. Videos without captions or automatic captions (some music videos, many live streams, private or age-restricted videos) have no transcript to read, so they can't be summarized either.

Alt + Shift + S opens the panel and summarizes the video you're watching. Change it at chrome://extensions/shortcuts.

• Sign in with Google first. AI summaries need an account so we can apply the free plan.
• The free plan includes 3 AI summaries a week, for videos up to 30 minutes. The panel tells you when they come back.
• If it says the AI took too long, try again. Very long videos can take a little longer to start.

Open Settings (the gear in the panel, or the Insightube icon in Chrome's toolbar). Summary language sets the language summaries are written in; Default translation sets the language transcripts and summaries are translated into. There are 69 languages to choose from.

Click the History button in the panel or in Settings. Every summary you've made is saved in your browser, with any translations, and you can search them by title, channel or idea.

Unlimited AI summaries and insights, summary translation into any language, and summaries of videos longer than 30 minutes. US$4.99 a month, or US$29.99 a year (about US$2.50 a month).

Settings → Manage subscription opens Stripe's secure page, where you can switch between monthly and yearly, update your card, download invoices or cancel. If you cancel, Pro stays on until the end of the period you've paid for.

Pro usually turns on within a minute of paying. Close and reopen Settings, or reload the YouTube tab. If it still shows Free, email us from the address you signed in with and we'll fix it.

Settings → Delete account. Any Pro subscription is cancelled first, then your account is removed from our servers. Summaries saved in your browser stay on your computer until you remove the extension.

Only when you ask for a summary or translation: the video's title and transcript, to create it. They aren't kept afterwards. Read the full privacy policy.
