Niche Hunter — YouTube Niche Finder

Find underserved YouTube niches with your own free YouTube Data API key — scans, outlier scores, filters, CSV export.

Niche Hunter scans YouTube through Google's official Data API using YOUR free API key, scores every video by how far it beats its channel's average, and hands you a filterable shortlist of proven winners. No queues, no shared limits, no data leaving your browser. 🎯 WHAT YOU GET • Keyword scans & channel scans with full stats • Outlier score ×N — views divided by the channel's recent average. ×3.0 means the video pulled 3× its channel's normal audience: demand outgrew supply, the strongest signal in niche research • Live filters — views, subscriber range, outlier threshold, length, publish window • Saved keywords — bookmark your niches, jump back in with one click • CSV & JSON export — take your research to Excel, Sheets or your own pipeline 🛡️ YOUR KEY.
