CommentGem collects every comment on any video and sorts out the funny ones, the questions, and what people really think.
The core of CommentGem is free forever. After 3 trial analyses you plug in your own free YouTube key — we walk you through it in 2 minutes.
We only handle what's needed to work: the comments you analyze, and your API key — used solely to fetch YouTube data. No selling, no watch-history reading, no account required.
Every AI answer costs us real compute — we can't afford to give AI away free. Pro ($4.99/mo) covers it and unlocks AI Chat and report downloads.
Add CommentGem to Chrome in one click. It lives in your toolbar, ready whenever you are.
CommentGem collects every comment on the video automatically — no scrolling, no loading batches.
Filter by humor, questions, or timestamps. Share the best comments as cards. Ask AI what viewers think.
Fair warning, upfront: after 3 free analyses, the free plan asks you to plug in your own free YouTube API key — we walk you through it in 2 minutes. No surprises later.

⚠ Sample data — install free to run it on any real video
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
How old was Rick Astley when he recorded this? He looks like he's 16 lol
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

CommentGem is always free to use. Pro unlocks AI Chat and report downloads — because AI analysis costs us money, we only charge for that.
Everything you need to explore YouTube comments.
Unlocks the AI. We can't afford to run AI analysis for free — Pro is what pays for it.

Yes — always free to use. You get 3 free video analyses to try everything. After that, you bring your own free YouTube Data API key (about 2 minutes to set up — the Help Center has the step-by-step guide) for unlimited comment collection. Filters, search, timestamps, and sharing are free forever. The only paid part is AI (chat, sentiment, report downloads), because AI analysis costs us money to run.
It's a free key from Google that lets you access YouTube's public data. You create it in the Google Cloud Console — the Help Center has illustrated instructions for every step. The key has a generous free quota (10,000 units/day) which is more than enough for most users.
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.
Yes — any public YouTube video with comments enabled. CommentGem collects every comment including replies, regardless of the total comment count.
Not on big videos, and we'd rather say so. Collection is complete — every comment is fetched, and the filters, search and timestamps run across all of them. AI Chat is the exception: language models have a context limit, so on a large video it reads a broad sample instead — the most-liked, the most-replied, the newest, a random slice of the long tail, and anything containing a question or a timestamp. On smaller videos that sample is the entire comment section. The panel always shows the exact number an answer was based on.
Pro ($4.99/month) unlocks unlimited AI Chat (free accounts get a taste — 3 questions a day), sentiment analysis, CSV & JSON report downloads, custom themes, and panel positioning. The honest reason AI isn't free: every AI answer costs us real compute, and we can't afford to give it away. Everything that doesn't cost us per-use stays free forever. Cancel anytime with one click.
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.
Yes — open the panel, Settings → Manage subscription → Cancel. One click, no contracts, no hidden fees. You keep Pro access until the end of your billing period.
