Frequently asked questions about SummarizAI
Answers about install, free quota, captions, Pro billing, and privacy. For workflows, see our guides.
What is SummarizAI?
A Chrome extension that adds AI YouTube summaries with chapters and clickable timestamps on youtube.com/watch.
How do I install the Chrome extension?
Click Add to Chrome on our install page or homepage—the button links to the Web Store when configured. See /install/ for steps.
Do I need an account?
Free tier requires sign-in so quota and settings sync across devices.
How many free summaries per day?
Three distinct YouTube videos per UTC day on Free. Re-summarizing the same video the same day does not use another slot.
When does my free quota reset?
Midnight UTC.
What counts as one summary on Free?
One distinct video ID per UTC day. Same video again the same day is free.
Do I need the extension to summarize?
Yes—summaries run in the panel embedded on YouTube watch pages.
Does SummarizAI work without captions?
We try captions first; when unavailable, audio transcription may run subject to limits and longer processing.
What languages are supported?
SummarizAI supports a language preference; quality depends on available caption tracks and audio clarity.
Can I summarize long videos and podcasts?
Yes when captions or usable audio exist—use timestamps to skim hour-long uploads.
Do timestamps seek the YouTube player?
Yes—click a summary timestamp to jump playback on the same tab.
What are comment insights?
Themes from visible top-level watch-page comments when threads load—supplementing caption-backed sections.
Is payment secure on Pro?
Checkout is hosted by Stripe; we never see your card number.
Can I cancel Pro?
Yes—cancel anytime; you keep Pro until the period ends.
Can I upgrade from the homepage?
Yes—choose a plan, sign in if needed, then complete Stripe checkout.
Does SummarizAI download my videos?
Summarization uses transcript-related content and metadata needed for the summary—see /privacy/ and our video data guide.
Is SummarizAI safe for school or work?
Treat sensitive recordings like any third-party AI—check policy, verify quotes via timestamps.
Why is the Summarize button missing?
Refresh the watch page, confirm the extension is enabled, and wait a few seconds after YouTube navigation.
Where is the Chrome Web Store listing?
Add to Chrome buttons link to the store when CHROME_WEB_STORE_URL is configured on the server—see /install/.
How is SummarizAI different from pasting a transcript into ChatGPT?
SummarizAI runs on the watch page with caption-backed timestamps—see our comparison guides in /blog/.
