Post Performance Predictor
Analyse your post draft and get a predicted engagement score with improvement tips.
about the post performance predictor
Most social posts are written, published, and forgotten — with no data until the engagement numbers come in too late to change anything. A performance predictor analyzes your draft before you publish and scores it against the signals that correlate with high engagement: hook strength, readability, CTA presence, optimal length, and format fit for the target platform.
The signals this predictor checks: does the first line create a specific tension? Is the reading level appropriate for the platform (LinkedIn rewards clarity; X rewards wit)? Is the post at the optimal length for the format? Does it have a CTA? Are there obvious engagement-bait phrases that could suppress algorithmic reach? Does the content match the platform's current algorithmic preferences?
Paste your draft, select your platform, and get a score plus specific improvement suggestions. Use it as a final check before publishing rather than a replacement for your editorial judgment — the goal is to catch the obvious misses (no CTA, too long for the platform, weak first line) before they cost you reach.
frequently asked questions
How can I predict if my social media post will perform well?
Check three things before posting: Is the first line specific enough to stop a scroll? Is the length appropriate for the platform? Does it end with a clear CTA? Posts that pass all three checks outperform those that don't by a consistent margin, regardless of topic.
What makes a high-performing social media post?
A strong, specific hook in the first line; content that delivers on the hook's promise; appropriate length for the platform; a relevant CTA at the end; and format fit (text vs. video vs. carousel) for the goal. This predictor scores all five dimensions.
Can AI predict social media performance?
AI can identify patterns that correlate with high performance — hook strength, length, CTA presence, readability — but cannot predict virality, which depends on timing, platform-specific algorithmic variance, and network effects. Think of a performance predictor as a pre-publish checklist, not a guarantee.
