Prepublish

Prepublish is a pre-publish script audit for YouTube creators. Most creators find out their retention problems from YouTube Studio, three days after the damage is already done. Prepublish flips that: you paste your script, or upload a video and let it get transcribed, before you ever hit record or publish, and the AI tells you where viewers are going to drop off.

Here's what happens when you run a script through it. The AI reads the whole thing and predicts a retention curve, the same shape you'd see in YouTube Studio, except it's a forecast instead of a post-mortem. It flags the specific lines and moments where attention is likely to fall off: a slow open, a rambling explanation, a promise that doesn't pay off fast enough. Then it gives you copy-paste rewrites for those exact spots, plus a rewritten title if the current one is underselling the video.

This is not a script generator. PrePublish doesn't write your video for you and it doesn't do keyword research. It's not an analytics dashboard either, it doesn't look backward at videos you already published. It looks forward, at the script sitting in your drafts folder right now, and tells you what's going to happen before it happens.

Every audit gets saved to your history and can be exported as a PDF, so you can track how your writing changes over time or hand a report to a client if you write scripts for other creators.

The paid plan is $19 a month or $200 a year, with 50 script audits a day, enough for a solo creator or a small agency running audits across several channels. There's an agency tier for teams that need more, contact for pricing.

If you don't want to commit to a plan yet, prepublish.ai/tools has a set of free tools, no account needed: Channel Scan (compares a channel's best and worst performing videos), Hook Analyzer, Title Analyzer, an Inauthentic Content Checker, a Script Word Counter, Words to Minutes, and a Talking Speed Test. They're built on the same idea, catch the problem before the video goes live, not after.
