For agencies and brand teams

Prove the cut works before the client pays to run it.

Creative calls defended with evidence beat creative calls defended with taste. Castle scores every cut, settles every A-versus-B, and gives the client a report link they can open themselves.

Three things it does for you.

01

Report without screenshots

Send the report link. Score, retention curve and fixes render for the client with no login, no export deck, no Friday-night Keynote.

02

Settle A versus B

Two cuts, one head-to-head, three concrete moves the weaker one should copy. The argument ends with evidence instead of seniority.

03

Triage the batch

Score every cut, sort by number, and spend senior review time only on the close calls.

The features that carry each job.

A score is a pre-flight instrument, not a crystal ball. Castle diagnoses the content's own signals with fixed weights, shows the reason behind every number, and treats anything under 4 points of difference as noise, and says so on the report. It can't see the client's audience, the media plan or the algorithm's mood, and it won't claim to.

Pick by the size of the book. Every plan gets the same full diagnosis; what changes is how much you can score a month, and how big the viewer panel is. Read how scoring works.

Not you? Creators.
