AI Virality Score Checker
Get a 0-100 virality score for any TikTok, Reel or video idea, with the exact factors holding it back.
Provide at least a URL OR a hook/caption.
A virality score is a 0-100 rating of how likely a short-form video is to break out of its usual reach. This free AI virality score checker computes it from 4 sub-scores: hook strength (first 1-3 seconds), expected retention and completion rate, shareability (would a viewer send this to a friend or save it), and trend fit within the video's niche.
Unlike a raw view counter, the score is diagnostic: each sub-score comes with concrete fixes ranked by impact, so you know exactly what to change before posting. It works from a URL (TikTok or Instagram Reel) or from just the hook and caption of a video you have not shot yet, which makes it useful at the idea stage too.
What is a virality score?+
A 0-100 rating of a video's breakout potential, computed from hook strength, expected retention, shareability and trend fit. Scores above 70 indicate strong viral potential; below 50 usually means the hook needs rework.
How accurate is an AI virality score?+
It is a pre-post diagnostic, not a guarantee: virality also depends on account health, posting time and audience. But hook and retention weaknesses it flags are the same signals platform algorithms punish, so fixing them reliably improves reach.
Can I check a video idea before shooting it?+
Yes. Paste the planned hook (the first 1-2 spoken seconds) and caption instead of a URL. The checker scores the concept and rewrites the hook if it is weak.
Does it work for both TikTok and Instagram Reels?+
Yes, both platforms. You can also audit a whole public account (last 30 posts) on either platform, once per day.
Is the virality score checker free?+
Yes, free and no signup. Agencies that want virality detection running continuously across a whole niche use Viral Manager (7-day free trial).
