The problem it exists to solve
Every creator eventually studies someone bigger. You open their channel, sort by most popular, and try to reverse-engineer what worked. The trouble is that a channel’s most-viewed videos mostly measure how many subscribers it had when they went up. Sort by views and you are largely sorting by history.
A million views on a channel that averages three million is an underperformer. A million on a channel that averages forty thousand is the best thing that ever happened to it. The raw number cannot tell those apart, so research built on raw numbers teaches the wrong lesson with total confidence.
What Cutline does instead
It works out what a normal video does on that specific channel, then finds the ones that beat it. Only long-form uploads count toward the baseline — Shorts have entirely different view dynamics, and mixing them in produces a median that describes nothing.
What comes back is not a leaderboard. It is the pattern the outliers share, written out in plain prose: the angle, the promise, the shape. From there Cutline writes six original ideas built on that pattern, scores each one on how likely it is to beat the same baseline, and turns the one you pick into a full script and a week of platform posts.
Two rules it follows
It never copies the video. Ideas are generated from why something worked, not from its transcript or its title. The goal is an original video that succeeds for the same reasons, which is the only version of this that is worth publishing.
It is not allowed to flatter you. When it scores six ideas, at most two may score above 80 and at least one has to come in under 60. A tool that tells you everything you might make is excellent is not giving you information.
Who is behind it
Cutline is built and run by one person — Daya, working independently from India. That has consequences worth stating plainly: it moves quickly, it is opinionated about how the research should work, and if you write in you are writing to the person who wrote the code.
See it work
Every analysis Cutline runs produces a public report. You can read real ones without an account — start from the home page and open any of the channels shown, or get in touch if something is not doing what it should.
