Questions
- How does the viral score actually work?
- We score five dimensions that correlate with retention on short-form: hook strength (first 1–2 lines), pacing, pattern interrupts, specificity over generic claims, and CTA quality. The overall score is calibrated against tens of thousands of viral and flop scripts — most scripts land in the 40–65 'Mid' range. Only sharp work breaks 80.
- What platforms does this support?
- TikTok, Instagram Reels, and YouTube Shorts. Each platform's scoring weights are different — TikTok punishes weak hooks hardest, Reels reward audio/visual loop points, Shorts reward retention payoffs.
- Should I trust the score?
- Treat it as a structured second opinion, not a guarantee. The score reflects script craft — hook, pacing, specificity, CTA. Performance also depends on visuals, audio, posting time, and account history. But scripts scoring below 50 rarely outperform scripts scoring above 70.
- Is this tool actually free?
- Yes — 5 free scores per hour, no signup required. If you want to take low-scoring scripts and remix them in your brand voice using proven viral structures, that's what the paid product does.
