SimilarTube

SimilarTube is a browser extension built for influencer marketers, sales teams, YouTubers and analysts who need to identify and vet YouTube channels quickly. Instead of querying a third-party influencer database that can lag behind for nano and micro creators, SimilarTube's AI bot scans YouTube itself, so results reflect the current state of the platform within seconds.

The extension works from a single channel as its seed and applies a look-alike algorithm to surface comparable channels. Each result carries metrics such as engagement rate (ER) and video view rate (VVR), so you can screen targets before committing to outreach. It also automatically extracts publicly available email addresses and linked social accounts (Facebook, Instagram, TikTok and others), and can match emails to templates to speed up an outreach campaign.

Different audiences get tailored value: marketers use it for look-alike discovery and contact enrichment, sales teams use it to grow lead databases, creators use it to map competitive niches, and analysts use the AI Insight feature to judge whether a niche is worth investing in. The extension is published on the Chrome Web Store as a Featured extension with a 4.8 rating, is available in 20 languages, and offers in-app purchases on top of free usage.
