YouTube Viral Video Finder
Search every niche at once for videos that got far more views than their channel usually gets — and find the topics that are working before you make your next video.
How to find viral videos with Global Outlier

Filter and sort
Set a minimum outlier score, a minimum view count and an upload window such as the last 7 days, then sort by best match, newest, most views or highest outlier score.
What Global Outlier searches
Every outlier TubeGrade finds goes into one shared database: videos from live searches, niche research, tracked competitors and the TubeGrade browser extension. Global Outlier searches all of it — more than 30,000 videos that got at least 3× their channel’s usual views — so you see breakouts from channels you have never heard of, not only the ones you already follow.
Each result shows the video’s outlier score, its views and when it was published, alongside the channel’s subscribers and country.
Global Outlier vs. Find Outlier
Find Outlier searches YouTube live for one keyword at a time — the right tool when you want today’s results for a specific search. Global Outlier searches the outliers TubeGrade has already found across every niche, instantly — the right tool for browsing ideas and spotting patterns across many channels.
Free vs Pro
Global Outlier is part of TubeGrade Pro. On the free plan you can still find outliers with 10 live Find Outlier searches a month, or try the free Outlier Finder preview without an account.
Frequently asked questions
What is a viral video finder?
A tool that surfaces videos performing far above normal. TubeGrade measures each video against its own channel instead of against all of YouTube, so a small channel’s breakout shows up next to a big channel’s, and you can see what made it work.
How does TubeGrade decide a video went viral?
With the outlier score: the video’s views divided by its channel’s average views. 3× is a clear outlier and 10× or more is a breakout. You can set the minimum score you want to see.
Where does the data come from?
From TubeGrade’s own database of outlier videos, built from live searches, niche research, tracked competitor channels and the browser extension. Video and channel numbers are public YouTube data. New outliers are added as they are found.
Can I search in other languages?
Yes. Titles are matched by meaning with a multilingual model, so you can search a topic and find outliers whose titles are written in other languages too.
Is Global Outlier free?
No — it is a Pro feature. Free accounts get 10 live outlier searches a month with Find Outlier, and anyone can use the free Outlier Finder preview without signing up.
