ViralAri

ViralAri is a web app that checks short vertical video drafts for TikTok, Instagram Reels and YouTube Shorts before you publish them. You upload the video file, and the app gives it a Viral Score from 0 to 100, which is an estimate of how well the opening holds attention, along with the parts that pull the score up or down. It also shows where viewers are likely to drop off, lists the three most important fixes, and writes five alternative hooks based on what is already said in the video.

The app can apply suggested edits with a Fix it for me option or let you work through them step by step. Exports are MP4 files at 1080x1920 and can include word-by-word animated captions, trims on full sentences, and silence and filler word removal. Paid plans add batch checks, a clip finder for longer podcasts or streams that suggests moments to turn into shorts, and on Studio a brand kit with your own fonts, colors and logo.

It is aimed at creators and small teams who post short-form video and want a check before going live. ViralAri does not connect to TikTok, Instagram or YouTube accounts and does not post on your behalf. The Viral Score is an estimate, not a guarantee of views.
