Prepublish

Predicts your YouTube video's retention curve from the script, before you publish.

Websubscriptionglobal

Prepublish is a pre-publish script audit for YouTube creators: paste a script, or upload a video to get it transcribed, before recording or publishing, and the AI predicts a retention curve — the same shape a creator would normally only see in YouTube Studio three days after the damage is already done — flagging where viewers are likely to drop off.
