SimilarTube is the clearest choice for marketers and agencies who need to build influencer prospect lists fast, without manually trawling YouTube. The email credit caps on lower tiers will frustrate anyone running high-volume outreach, and the $249.90/month Max plan is a significant jump from the $49.90 Outreach tier. If your goal is broader social media scheduling or content creation rather than YouTube channel prospecting specifically, look elsewhere.
What is SimilarTube?
SimilarTube is an AI-powered YouTube channel discovery tool available as a Chrome extension and web app. It uses a look-alike algorithm to scan YouTube directly and return similar channels in real time, surfacing key metrics including engagement rate and video view rate alongside each result. Users can filter, sort, and save results, and extract public contact information and social links for outreach purposes.
The tool is used primarily by marketers, influencer agencies, and sales teams building YouTube prospect lists. Paid plans add features such as CSV export, email credit pools for contact extraction, and a mail merge workflow. A Discord community provides user support, and a 7-day refund policy applies if fewer than 20 searches or 20 email matches have been used.
How we scored SimilarTube
Capability scores well for its niche: real-time YouTube scanning with ER and VVR metrics is a genuine differentiator over static databases, but the hard YouTube-only scope and absence of any cross-platform discovery keeps it out of the high teens. Ease of use is strong: a Chrome extension that triggers from inside YouTube, a 3-day trial, and a simple three-tier structure mean almost no onboarding friction. Value is the weakest point: the $249.90/month Max plan is a 5x jump from the $49.90 Outreach tier with no middle option, and the Starter plan's 300 email credits per month will run dry quickly for anyone doing real outreach campaigns. Delivery scores modestly: the product appears to do what it claims, but the tool is relatively young (launched 2024), the user base is small (around 5,000 users per third-party data), and the email credit reset model creates a hidden consumption risk that is not prominently disclosed in marketing.
Pros and cons
What we liked
- Real-time YouTube scanning bypasses stale database lag, surfacing nano and micro influencers that static platforms miss.
- Engagement rate and video view rate are shown per result, letting users screen channel quality without opening each channel separately.
- Low-friction 3-day trials ($1.99 for Starter, $4.99 for Outreach) let buyers test the actual paid feature set before committing to a monthly bill.
Where it falls short
- Coverage is YouTube-only: there is no discovery for Instagram, TikTok, or any other platform, which is a hard limit compared to broader influencer tools.
- The jump from the $49.90 Outreach plan to the $249.90 Max plan is a 5x price increase with no intermediate tier, leaving high-volume users with a steep step up.
- Email credit counts reset monthly and are consumed per successful match, so a campaign requiring thousands of contacts will burn through the Outreach plan's 3,000 credits faster than the search quota.

Who should use SimilarTube?
Influencer marketing managers at agencies who regularly need to find 20 to 200 YouTube channels in a specific niche will get the most from SimilarTube. The combination of real-time scanning, ER and VVR metrics, and email extraction means a researcher can go from a single seed channel to a qualified outreach list in one session rather than across several tools. Sales teams targeting YouTube creators as potential customers, and brand managers doing competitive landscape mapping on YouTube, are also natural fits.
Creators looking to find collaboration partners can use the free or Starter tier for occasional searches. However, anyone who needs Instagram, TikTok, or multi-platform influencer discovery should look at a broader platform instead. For teams whose primary need is social media content scheduling and publishing rather than prospecting, Simple Post covers that job more directly and at a lower price point.
Skip it if: Teams needing multi-platform social media management or content publishing tools.

Frequently asked questions
Is there a genuinely free plan, or just a trial?+
There is a limited free tier that allows basic channel discovery. Paid plans start with a 3-day trial at $1.99 (Starter) or $4.99 (Outreach) before converting to the full monthly rate.
What does an 'email credit' actually mean?+
Email credits are consumed only when SimilarTube successfully finds a public email address for a channel. The Starter plan includes 300 credits/month and the Outreach plan includes 3,000. Unused credits do not roll over.
Does it work on browsers other than Chrome?+
The extension is available for both Chrome and Firefox. The standalone web app works in any modern browser regardless of extension support.

Full refunds are available within 7 days of the initial subscription, provided fewer than 20 searches and fewer than 20 email matches have been used.
Does SimilarTube cover platforms other than YouTube?+
No. The tool is YouTube-only. It extracts public social and contact links from YouTube channel pages, but the discovery algorithm itself only searches YouTube channels.
