Are these two channels a good collab?
The #1 reason collabs flop is a size or audience mismatch — not too few subscribers. Paste two channels and get a fit score in seconds: size match, niche overlap, engagement, and cadence.
The 2–3× rule (and why size beats fame)
Creator data is consistent: collaborations grow both channels most when the partners are within roughly 2–3× of each other's size, share an overlapping (not identical) audience, and both have real engagement. A 5K channel with a 5% like-rate is often a better partner than a 200K channel at 0.5% — engaged audiences actually click through and subscribe. Chasing a creator 10× your size usually ends in silence; even a yes rarely moves the needle because the audiences are too far apart.
What this tool checks
- • Audience-size fit — your subscriber ratio against the healthy 2–3× band.
- • Niche / topic overlap — shared themes pulled from both channels' recent video titles.
- • Engagement quality — the median like-to-view rate of each channel (quality over vanity subs).
- • Cadence fit — how close your posting rhythms are, which makes repeat collabs easier.
FAQ
How do you decide if two channels are a good collab fit?
We pull each channel's public stats and last 20 uploads, then score four research-backed factors: audience-size fit (partners within ~2–3× subscriber range grow each other best), shared niche/topics (from recent video titles), engagement quality (median like-to-view, because an engaged small channel often out-performs a passive big one), and how close your upload cadences are.
Do you show audience overlap percentage?
No. YouTube's public API doesn't expose audience demographics, so any 'overlap %' would be made up. We only score real, public signals — and we're upfront about that.
Why does size matter so much?
Research and creator data consistently show collaborations grow both channels most when the partners are within ~2–3× of each other. Punching up to a creator 10× your size usually means they ignore you, and even if they say yes, the audience gap limits the lift.
Is it free?
Yes — no signup. It's rate-limited to a few checks per 15 minutes to protect the API quota.
