publishub

publishub is an AI video analyzer for Reels, TikToks and YouTube Shorts, aimed at freelance video editors, UGC creators and creators who edit their own videos. A user uploads an MP4, MOV or WEBM file (up to 500 MB, per the FAQ; the page's feature section lists up to 50 MB) and publishub transcribes speech, measures pauses and scene changes, and returns editing notes tied to specific seconds with reasons. Users can optionally upload an Instagram Insights retention screenshot so the tool reads the real curve and adds a prediction. The site says it does not edit automatically, does not connect to editors such as CapCut, Premiere Pro or DaVinci Resolve, and leaves all changes to the user. It describes a free test without an account, a free account with a complete first analysis, and paid monthly plans. The page is built around an illustrative example and states that results shown are not real creator data.
