I just rickrolled my entire office meeting by sharing this link as 'Q4 budget report'

The fact that this has 1.5 BILLION views and people still fall for it is peak humanity

Genuine question — is this the most viewed music video ever or does Despacito still hold the record?

The choreography at 1:24 is actually really impressive. Rick's moves were ahead of their time

My teacher just rickrolled the entire class during a zoom lecture. The man embedded it in his PowerPoint!

Unironically, Rick Astley has a fantastic voice. The bass at 0:58 is incredible with good headphones

I first heard this in 2007 when my friend sent me a 'free iPhone giveaway' link. 17 years later, I'm still not over it

FAQ

Frequently asked questions

Is CommentGem really free?+

Yes. You get 3 free video analyses to try everything. After that, you bring your own free YouTube Data API key (takes about 2 minutes to set up through Google Cloud Console) for unlimited comment collection. Filters, search, timestamps, and sharing are always free.

What is a YouTube API key and how do I get one?+

It's a free key from Google that lets you access YouTube's public data. You create it in the Google Cloud Console — we provide step-by-step instructions inside the extension. The key has a generous free quota (10,000 units/day) which is more than enough for most users.

How is my API key stored?+

Your YouTube API key is stored in your browser's local storage and is sent to our server to make YouTube API calls on your behalf. We're working on a fully client-side approach where the key never leaves your browser. Your key is only used for YouTube data fetching and nothing else.

Does it work on any YouTube video?+

Yes — any public YouTube video with comments enabled. CommentGem collects every comment including replies, regardless of the total comment count.

What does Pro include?+

Pro ($4.99/month) adds AI-powered features: chat with comments using Gemini AI (no separate API key needed — we bundle it), sentiment analysis, CSV report downloads, custom themes, and panel positioning. Cancel anytime with one click.

How does the share feature work?+

Select any comment, and CommentGem generates a beautiful shareable card with the comment, username, and video context. You can share via a unique link, WhatsApp, Twitter/X, email, or copy the image directly. Sharing is always free.

Can I cancel Pro anytime?+

Yes, cancel anytime through your account settings. No contracts, no hidden fees. You keep Pro access until the end of your billing period.
