What an AI virality score tells you.
The short answer
A virality score is an AI tool's estimate of how likely a clip is to get attention and shares. OpusClip, Klap and quso each have one, with different scales and factors, so a number from one tool does not compare with another. The scores are most useful for deciding which clips from one video to look at first. They cannot see the timing, the audience or what the platform will do after you post, so test one against your own results before relying on it.
What goes into each score
OpusClip 0 to 99
Hook, Flow, Value and Trend, with extra checks such as relevance to your prompt. Shown on Starter and Pro. Higher scores, it says, suggest a greater chance of engagement and shares. Clips are sorted by the score by default.
Klap 0 to 100
Hook strength, pacing, retention signals and topic relevance. Its page suggests posting clips that score 90+ first, testing those in the 70s and 80s, and skipping the rest.
quso.ai 75 to 99
Trends, Hook & Flow, Engagement and Shareability. Its scale starts at 75, labelled average, and its help page says the score is a prediction and not a guarantee.
Two things stand out. The scales differ, so a 78 means different things in different tools. And each list mixes things a file can show, such as the hook and the pacing, with things that depend on the world outside it, such as trends and shareability, which an AI has to judge.
What a score is good for
- Triage. If a tool has cut 12 clips from one video, the score gives you an order to watch them in.
- A rough filter when you post at volume and cannot watch everything.
What it cannot tell you
Views depend on the topic, the timing, the audience and what the platform does after you post, and most of that is not in the file. A high score does not mean a clip will do well, and a low one does not mean it will fail. A score also rarely tells you what to change: knowing a clip got a 72 does not tell you what to do to it.
How to test a score yourself
- 1.
Write down the score before you post
Keep a simple sheet with the clip, the score and the date. Writing it down first stops you remembering only the hits.
- 2.
Post at least 20 clips, including some low scorers
If you only post the high scorers, you can never see whether the low ones would have done just as well.
- 3.
Record the results after the same number of days
Seven days after posting is a fair choice. Use a measure you care about: views, watch time or shares.
- 4.
See whether higher scores really did better
Split the clips into a high-score half and a low-score half and compare the two. Twenty posts is a rough test, not proof, but it will tell you more about your audience than any general claim.
What we do differently
NeuroVidz does not give a virality score, and it does not predict views. Its Craft score describes how a clip is built: Hook, Hold and Feel are measured from the file, and Story is an AI read, labelled as one. What you act on is the edit plan, such as the first word landing at 4.8 s against a target under 1 s, and then the re-check of v2. Its limit is the same as every other tool's: it cannot see what happens after you post. Every check is listed here.
Questions
What is a virality score?
A number an AI tool gives a clip to estimate how likely it is to get attention and shares. Tools such as OpusClip, Klap and quso use it mainly to rank the clips they cut from a long video, so you know which to look at first. Each tool has its own scale and its own factors.
Are virality scores accurate?
The help and product pages we read explain what goes into each score but give no accuracy figure, and we have not tested them ourselves. quso says directly that its score is a prediction and not a guarantee, and that results depend on timing, audience and platform algorithms. The way to find out is to compare a score with your own results over at least 20 posts.
Is a score of 75 good?
It depends on the tool. On quso, 75 is the bottom of the scale, labelled average. On OpusClip's 0 to 99 and Klap's 0 to 100, it sits at a different point in the range, and Klap's page suggests testing clips in the 70s and 80s after posting the 90+ clips. The numbers do not compare across tools.
Does NeuroVidz give a virality score?
No. It gives a Craft score that describes how a clip is built, and it does not predict views or virality. It is for comparing v1 and v2 of the same clip.
Every check and its target is on the methods page, and the sample page shows a real result without an account.
