Features & Capabilities

Comet is a user-friendly Chrome extension that enhances your browsing experience by displaying Reddit comments on YouTube videos and other webpages. Instead of relying on YouTube’s native comment section, Comet replaces it with the relevant Reddit discussion, providing richer and often more insightful conversations.

When you browse a webpage posted on Reddit, Comet's icon turns blue, allowing you to quickly access Reddit posts and comments through a convenient popup. Switching back to YouTube's original comments is effortless with a simple click. This extension respects privacy as it contains no ads, collects no data, and requires no signup.

Perfect for users who want to explore community opinions beyond traditional comment sections, Comet integrates Reddit discussions seamlessly into your everyday browsing.

User Reviews

Users find the add-on useful for viewing Reddit comments on videos and generally report it works well. Multiple reviewers warn it triggers Reddit rate-limiting (error 429), which can block Reddit browsing; disabling the add-on fixes this. Users also want it to be passive/by-request and have raised maintenance/update concerns.

Pros

Adds Reddit comments directly to YouTube and other webpages, making it easy to see discussions alongside content
Reported to work well and function reliably by multiple users
Helps surface Reddit discussions that some users find saner or more thoughtful than native YouTube comments

Cons

Triggers Reddit rate-limiting / error 429 (too many requests), blocking Reddit access when multiple tabs are opened — reported by several users
Runs/acts by default and can be intrusive; users say disabling the add-on stops the problem (suggesting it shouldn’t be always-active)
Maintenance concerns noted (users reported long periods without updates)

Recent reviews

As of recent, it prevents YouTube comments from displaying, and it does not display reddit threads either, needs to be fixed ASAP!

Since now, the addon is not working and will disable both youtube comments and reddit comments - they are not visible anymore.

I've been occasionally noticing that youtube comments don't appear at all on some videos and narrowed the issue down to this extension. Came here to check if others had the same issue and realize that this extension is what's causing the constant 404 errors on reddit as well! I haven't even opened reddit in hours and I'll still be rate limited leading to constant frustration and having to delete cookies. Plugin still kinda works though! Can't recommend.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
