SimilarTube

SimilarTube is an AI-powered YouTube channel finder for brands/SaaS founders, marketers, agencies, partnership teams, and creators. Paste a YouTube channel URL or @handle to find related channels by content, niche, and audience—without building a giant keyword list. Review channel metrics (subscribers, views, engagement rate, video view rate), extract publicly listed business emails and linked social accounts where available, organize prospects with Saved Lists, and continue research in the SimilarTube Chrome extension while browsing YouTube.

SimilarTube offers 10 limited free searches every 24 hours, without email matching, plus two free website tools (similar-channel finder and YouTube email finder).
