Predict your post's engagement score, analyze hook strength, and get actionable improvement tips before you hit publish.
The virality predictor scores your draft post before you publish it, so you can fix a weak hook or unclear payoff while it still matters. Paste your caption or tweet and get a 0-100 engagement score, a hook-strength rating, and specific, plain-English tips on what to change. It works for X, Instagram, LinkedIn and TikTok copy, runs in seconds, and needs no signup.
Calibrating Virality Predictor......
Please wait a moment
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.
Drop in the full caption, tweet, or post copy exactly as you plan to publish it, including the first line, since the hook carries most of the weight.
The tool returns a 0-100 engagement score, a separate hook-strength rating, and a breakdown of which elements are helping or hurting.
Rewrite the weakest element it flags, usually the opening line, then paste the new version back in to see the score move.
Compare two or three hook variants and publish the one that scores highest. The estimate improves your odds; it does not guarantee reach.
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.
The number is a repeatable estimate, not a prophecy. Below 40 usually means the hook or value is buried and most people will scroll past; 40-70 is a solid post that could climb with a sharper opening; above 70 signals the traits that correlate with strong reach are all present. Because scoring is deterministic, the same draft always scores the same, which is what lets you A/B two hooks and trust the comparison.
Virality also depends on timing, your audience, and plain chance, none of which any tool can see. Where this predictor earns its keep is the part you control: rewriting the first line until the hook lands, tightening the promise, and cutting the friction that stops people sharing. Run two or three versions of the opening and ship the one that scores highest.
The score is based on patterns found in highly viral content, evaluating hook strength, clarity, and format. It serves as a strong directional indicator.
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.
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.
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.
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.
Paste your draft and the tool scores it on factors like hook strength, format and clarity, and suggests improvements, so you can refine it before publishing. The score is a deterministic estimate, not a guarantee.
It evaluates elements that correlate with engagement, such as a strong opening hook, readability and structure, and returns a score with specific tips to raise it.
No. Virality depends on timing, audience and luck; the tool gives a repeatable estimate and actionable feedback to improve your odds, not a promise of results.
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.
No. It signals that the fundamentals, hook, clarity, format, are strong. Reach still depends on timing, audience, and the platform algorithm.
