About OutlierScan - Find YouTube Video Outliers
Find the videos that are blowing up while you browse YouTube.
An outlier is a video that massively beats its own channel's normal. When a channel that usually gets 50K views suddenly gets 2M, that video is a 40× outlier, and it happened for a reason: the title, the thumbnail, the topic or the format hit a nerve. Those are the videos worth studying, because they are proof of what an audience wants right now, not a guess.
OutlierScan puts that score under every video on YouTube, so the proof is visible everywhere you browse. Instead of guessing what to make next, you see exactly what is working on any channel, in any niche and borrow the pattern for your own videos.
WHAT YOU GET
- Outlier scores on every video: home page, search, subscriptions, channel pages. Color-graded badges from a quiet 1× to a flaming 100×+.
- A data panel on every watch page: the video's view curve, views per hour right now, engagement, and how the channel normally performs.
- Best outliers per channel, open any video and see that channel's biggest hits ranked by how far they beat the channel's own normal. The fastest way to reverse-engineer what an audience rewards.
- One-click save: hit the star under any video and it lands in your OutlierScan library, organized into categories you define.
- A full research app: your account connects to outlierscan.com: a feed of the internet's current outliers, winning title formats mined weekly, trending topics, a content calendar and more.
