The best free YouTube outlier finder extensions in 2026
An outlier finder marks videos that got many times more views than their channel usually gets. These are the Chrome extensions that do it on YouTube itself, what they cost, and who each one suits.
We make Outvyr, so we're biased. Everything about the other tools comes from their own websites or Chrome Web Store listings, checked 29 October 2026. If something here is out of date, email support@scopras.com and we'll fix it.

How to choose
- You browse YouTube for ideas and don't want another account: Outvyr. Scores appear on every page, and Dissect shows the hook and the viewer questions behind a hit.
- You want to search outliers by keyword in a database, with AI title and thumbnail tools: 1of10.
- You already use OutlierKit's website: its extension puts the same scores on YouTube search and channel pages.
- You want views per hour and engagement next to the score: TubeGrade or 1of10.
- You want keyword research and channel analytics more than outliers: vidIQ or TubeBuddy (see Outvyr vs vidIQ, Outvyr vs TubeBuddy).
Outvyr
A free Chrome extension that scores every video on YouTube against its own channel's median views, on Home, Search, channel pages and the sidebar. Filter any page to 3x+ or 10x+ videos, small channels or the last 30 days. Press Dissect under a video to read its first 30 seconds word for word, see its speaking speed and read its comments sorted into questions, "part 2" requests and complaints. No account; your data stays in your browser. Free plan: scores on every page (the top ones after the 6th are locked), 3 dissects a day. Pro: $9 a month or $39 a year.
OutlierKit
OutlierKit's extension is free to install and shows colour-coded multiplier badges on YouTube search results and channel Videos tabs; hover a badge for the channel average. You sign in with an OutlierKit account (any plan or its free trial).
1of10
1of10 is an outlier search website with AI tools. Its extension adds outlier scores and rankings on YouTube's home feed, watch, channel and search pages and Shorts, plus views per hour and title and thumbnail change history. There is a free plan with limits; paid plans start at $19 a month. Outvyr vs 1of10.
TubeGrade
A newer extension that shows outlier scores, views per hour and engagement on videos, channels, search results and the home feed, with some features on a Pro plan.
Mittalmar: Research For YouTube
A small free extension that highlights outlier videos on YouTube with a coloured bar. Good if you only want a quick visual flag.
Questions
What is the best free Chrome extension to find outlier YouTube videos?
It depends on how you work. If you want scores on every YouTube page without an account and want to read why a video worked (its hook and its comments), use Outvyr. If you want to search a big outlier database by keyword with AI tools, 1of10 fits. If you already pay for OutlierKit, its free extension adds badges to search and channel pages.
Do I need an account to see outlier scores?
Not with Outvyr: install it and the scores appear. OutlierKit's extension asks you to sign in to an OutlierKit account, and 1of10 works with a 1of10 account.
How is an outlier score calculated?
A video's views divided by its channel's usual views, usually the median of recent uploads. Tools differ in which uploads they count, so the same video can show a slightly different score in each.
Is there a free vidIQ outliers alternative?
Yes. vidIQ is a full growth suite with keyword research and an AI coach. If you only need outlier scores on YouTube, Outvyr's free plan, OutlierKit's extension or TubeGrade cover that.
