The Virality Predictor scores a post's likely engagement before you publish, grades the strength of your hook, and hands back concrete rewrite tips. Instead of guessing what will land, you get a pre-publish read on the one thing that decides reach — whether people stop scrolling in the first line.

## About

### Score a post before you publish

The virality predictor rates your draft against the traits that consistently drive shares — a scroll-stopping hook, emotional pull, clarity, and an obvious reason to repost. You get a score plus specific, plain-English suggestions on what to strengthen, so you can iterate on the copy while it still matters.

### What actually makes content spread

Reach is rarely luck: high-performing posts tend to trigger a clear emotion, promise fast value, and lower the effort required to share. This tool makes those hidden signals visible for your own writing, helping you A/B different hooks and openings without waiting days for the algorithm to decide.

## FAQ

### How accurate is the engagement score?

The score is based on patterns found in highly viral content, evaluating hook strength, clarity, and format. It serves as a strong directional indicator.

### How do I know if my post will go viral before publishing?

Paste your draft into the Virality Predictor. The AI scores it 0–100 based on hook strength, emotional triggers, clarity, and format patterns found in top-performing posts. A score above 70 indicates strong viral potential.

### What makes a social media post go viral?

Viral posts share common traits: a strong opening hook in the first line, emotional resonance (curiosity, surprise, or value), concise formatting, and a clear call-to-action. This tool evaluates all of these dimensions and tells you where to improve.

### Can I use this for Instagram, LinkedIn, and Twitter posts?

Yes. The predictor is platform-agnostic — paste any post copy regardless of the platform. It analyzes the text structure and hook quality, which are consistent viral signals across Instagram, X (Twitter), LinkedIn, and TikTok captions.

### What is a hook and why does it matter for virality?

A hook is the first 1–2 sentences of your post. It determines whether someone stops scrolling or keeps going. Posts with weak hooks lose 90% of potential readers before the second line. The predictor scores your hook and suggests a stronger alternative.

### Which platforms is the prediction tuned for?

The hook and format analysis applies to short-form social posts broadly — X/Twitter, LinkedIn, and Instagram captions — since they all reward a strong first line.

### Is a high score a guarantee of going viral?

No. It signals that the fundamentals — hook, clarity, format — are strong. Reach still depends on timing, audience, and the platform algorithm.
