See what a YouTube video is really doing

Engagement rate, hidden tags, views per day and a keyword score, right on the YouTube page. Free, no sign-up, no ads.

Install stepsChrome Web Store listing is on its way. Until then it installs in one minute by hand.

What it adds to YouTube

Video panel

Engagement rate with a grade, views per day, likes and comments as a share of views, and the video's hidden tags with one-click copy. Reads the page itself, no key needed.

Channel panel

Engagement across the last 10 uploads, views per subscriber, uploads per month, Shorts share, channel keywords, and which recent videos beat the channel's average.

Search scores

Under every result: views per day, engagement grade, channel size and a views-to-subs ratio. Small channels that are ranking get flagged, the sign of an open topic.

Suggested tags in Studio

Under the Tags box when you upload or edit a video: tags ranked by how many of the top 20 videos ranking for your title actually use them, then YouTube autocomplete. Click to add, or add the top 10. Hover any tag to see why it is there.

Keyword tool

Type a topic and get an overall score, interest, competition, "people also search" ideas and the top 20 results with the numbers that matter. Cached so it stays fast.

Title, description and tag writer

Ten title angles with character counts, a description with timestamps and links placeholders, and a tag list under 500 characters. Never invents facts.

Honest by design

Scores are estimates from the top results, and the extension says so. No "search volume" made up from thin air, no upsell, no login wall.

Install

The Chrome Web Store listing is being reviewed. Until it is live, install the folder by hand (one minute):

  1. Download the extension zip from the link your Passive Array contact sent you and unzip it anywhere on your PC.
  2. Open Chrome and type chrome://extensions in the address bar. In Edge use edge://extensions.
  3. Turn on Developer mode (switch in the top right).
  4. Click Load unpacked and choose the unzipped folder.
  5. Open any YouTube video. The panel appears in the sidebar. Click the extension icon for the keyword tool.

Questions

Is it really free?

Yes. The YouTube numbers come from the official YouTube Data API on a free allowance, and the video panel does not use the API at all.

Do I need an account?

No. Nothing to sign up for, nothing to log in to, and the extension never sees your Google account.

What does it send anywhere?

Only the video ID, channel link or keyword you are looking at, to this site, so the API key can stay on the server. Details in the privacy policy.

Are the scores real search volume?

No. They are estimates built from the top 20 results: how much they are watched, how big the channels are, how fresh they are. The tool says this on every report.

Want to follow channels over time?

A free account watches 3 channels. Pro watches 100 with a Monday email of who moved, from $9 a month.
