Looking for a good whitespace finder tool for YouTube niches

[dimicag]

Hello everyone.

Has anyone found a reliable way to spot content gaps on YouTube? I run a mid sized channel and I keep guessing at video ideas instead of actually knowing what topics are underserved. I want something that can look at a niche, show me what audiences are searching for, and highlight areas where competition is low but demand is decent.

I have tried a couple of keyword tools but they feel built for Google search, not YouTube specifically. Ideally I want something that factors in search volume, existing video saturation, and audience retention patterns. Does a tool like this actually exist, or is this still mostly manual research and gut feeling?

Would love real recommendations, not just generic SEO tools rebranded for video.

Yes, tools built specifically for this exist now.

OutlierKit and TubeLab use outlier detection. They find videos that perform 5 to 10x above a channel's normal average, which signals real demand with manageable competition, even from small channels.

This is essentially what a whitespace finder does for YouTube: it maps where audience demand is high but existing content supply is thin, so you can spot the gap before you commit to a video.

TubeBuddy's Opportunity Finder analyzes videos after you publish, not before, so it's better for optimization than initial gap finding.

vidIQ relies mainly on search volume, CPM, and competition level, similar to what you've already tried.

None of them factor in retention data directly, since that only exists in YouTube Studio once you've already published something. So the common workflow is to use an outlier tool to find the gap, publish a test video, then validate with Studio retention data.
