YouTube does not publish a list of similar channels, but it shows one every day: the “Up next” videos beside a video are what YouTube thinks the same viewer will watch next. If the same channel keeps appearing next to several of your best videos, YouTube clearly sees it as a neighbour — a competitor for the same audience.
We take the channel’s five most-viewed videos, read the recommendations next to each of them and group the recommended videos by channel. Channels that appear next to more of the five videos rank higher; among equals, those with more views come first. The channel itself is left out.
Each result shows how often it appeared and the recommended videos we found, so you can immediately compare their thumbnails with yours. Press “Open channel thumbnails” to see all of a neighbour’s videos and its outliers.
This is a quick signal rather than a perfect map: recommendations change over time and differ by country. Small channels with few videos may not get enough recommendations — try a bigger channel in the same niche.
Frequently asked questions
Why these channels and not the ones I expected?
The list comes from YouTube’s own recommendations, which follow viewer behaviour rather than topic labels. Surprising results are often the most useful.
How long does it take?
Usually a few seconds. We make five lookups, one per top video, and show progress while they run.
Does it work for Shorts-only channels?
Partly. Shorts recommendations work differently, so results are best for channels with long videos.
Is my search saved?
No. Results are cached on our side for a day without any personal information, and nothing is tied to you.
