SimilarTube

SimilarTube finds YouTube channels that are similar to one you already know. You paste a channel link or @handle, and its AI search analyses that channel's content, niche and audience, then returns look-alike channels. It is aimed at marketers, agencies and brands looking for creators to sponsor, and at creators researching their own niche and competitors.

Each result comes with the numbers you need to judge a channel quickly, including subscribers, views and engagement. For outreach, SimilarTube also shows publicly listed business emails and social links where channels provide them, and higher plans add CSV export so lists can move into a CRM or spreadsheet. Filters, favourites and blocking help narrow a long list down to the creators that fit. A Chrome extension lets you start a search from YouTube itself.

Pricing is shown openly. Starter has a $1.99 3-day trial and then costs $25.90 per month for 50 searches and 300 email credits. Outreach has a $4.99 trial and then costs $49.90 per month for 500 searches, 3,000 email credits and CSV export. Max costs $249.90 per month for 3,000 searches and 20,000 email credits. Trials renew into the paid plan unless cancelled.

Results depend on the channel, and SimilarTube notes that it does not guarantee a fixed number of matches or that every channel has a public email.
