What the score measures
Virality Score is not a single metric. It combines six distinct engagement signals, each weighted by content type, to produce a composite score per segment.
Hook strength
Opening sentence language patterns that correlate with watch-through
Audio energy
Peaks in vocal energy, pace, and emphasis intensity
Emotional sentiment
Polarity shifts, story beats, and emotional payoffs
Quotability
Declarative, concrete, and memorable sentence structures
Topic density
Information-to-time ratio — high value per second
Call-to-action presence
Detected implicit and explicit prompts to the viewer
How Virality Score works
Transcribe and analyze
CaptionX transcribes your footage and runs the scoring model across every sentence and segment simultaneously.
Score map generated
A score from 0–100 is assigned to every segment. A heatmap overlay shows score intensity across your timeline.
Breakdown by signal
Drill into any segment to see its score breakdown — which signals are high, which are pulling the score down, and why.
Act on the data
Use scores to select clip candidates, choose your thumbnail frame, reorder your edit, or identify the strongest hook to open with.
Who it's built for
Performance-focused content creators
If you track views, watch time, and retention — Virality Score gives you a pre-publish signal to optimize against. Know before you post which moments will hold attention and which will lose it.
Social media managers and agencies
Accountable to client performance metrics? Virality Score removes subjectivity from clip selection and hook choice — decisions backed by data, not guesswork.
Podcast editors building social clips
The hardest part of clip production is choosing which moments to cut. Virality Score ranks every candidate automatically — highest-scoring segments get clipped first.
