Extensions such as "Tags for YouTube" or similar developer tools may display the "Unlisted" badge on a video thumbnail if you already have the link.

| Feature | Benefit | |---------|---------| | One-click unlisted filter | Instantly see only unlisted videos on your channel | | Visual badge | Unlisted status appears without clicking each video | | Export list (advanced) | Copy all unlisted video URLs to a text file | | Check other channels | Usually disabled for privacy reasons—most ethical extensions respect that unlisted = not public |

⚠️ Important: No legitimate extension can “find” another user’s unlisted videos. If an extension claims to do that, it is violating YouTube’s terms of service and may be malicious.

Title: Doesn’t really “find” hidden videos

Review:
I installed this hoping it would discover unlisted videos from any channel. Instead, it only shows unlisted videos already visible in a playlist or channel’s video list if you have the link. It doesn’t scrape or reveal anything truly hidden. The description should be clearer: this is a display helper, not a search tool for unlisted content. Uninstalled.

To understand the limitations of these extensions, one must understand the types of YouTube video visibilities:

The Technical Limitation: YouTube’s Data API v3 does not provide a search filter for "unlisted" videos. When a user views a channel, the API returns a list of public uploads. Unlisted videos are withheld from this list unless the user possesses the specific video ID (the link). Therefore, an extension cannot "scrape" a channel to find videos the API refuses to provide.

What it claims: "Login with Google to scan for unlisted videos." Reality: It requests OAuth permissions like "See your email" and "Manage your YouTube account." Once granted, it steals your session cookie and uploads spam videos from your account.

Golden Rule: If an extension asks for permission to "Read and change all your data on youtube.com" AND "Manage your downloads," uninstall it immediately.

Instead of chasing a mythical extension to reveal other people’s hidden videos, consider changing how you manage your own unlisted content.

Invest in a bookmark manager like Raindrop.io or Pocket. When you receive an unlisted YouTube link, save it with specific tags (e.g., client_approval_2025). Create a shared collection for your team.

For YouTube Studio users, the best "extension" is actually a Google Apps Script. You can write a 10-line script that connects to the YouTube API V3, fetches your uploads, filters by privacyStatus == 'unlisted', and emails you a weekly CSV report.

This is 100% legal, secure, and more effective than any browser extension.
