What is a video virality score?

The Postmixr virality score (0–100) summarizes hook strength, pacing, call-to-action clarity, and retention risk for short-form content. It is not a guarantee of views; it is a structured critique of your actual video before you post.

How AI video analysis works

We transcribe speech, detect scene cuts, sample key frames, and run vision AI on on-screen text and visuals. A synthesis model writes why the video works and how to improve it, using the same pipeline we use internally for creative research.

  • Works with uploads or public YouTube, TikTok, and Instagram links (IG best-effort).
  • Reports expire after 24 hours: we do not permanently store your source video.
  • Free tier: 3 full video tool runs every 6 hours.

TikTok, Reels, Shorts, and long-form

The analyzer is platform-agnostic. Optional platform hints tune the narrative for TikTok, Reels, or YouTube Shorts. Videos up to 30 minutes are supported on the free tier.

FAQ

What is a video virality score?

A 0–100 estimate of how well your video follows patterns common in high-performing short-form content: hook strength, pacing, CTA, and retention risk.

How does AI predict if a video will go viral?

We transcribe speech, sample key frames with vision AI, and analyze editing pace. A creative-director-style model synthesizes a structured report, not a guaranteed prediction.

Can I analyze a TikTok before posting?

Yes. Paste a public TikTok URL or upload an exported file. You get a score and actionable fixes before you publish.

Does this work with YouTube Shorts and Instagram Reels?

Yes. Paste a public YouTube, TikTok, or Instagram link, or upload a file. Instagram fetch is best-effort.

What is hook strength and retention risk?

Hook strength scores how compelling the first few seconds are. Retention risk flags slow pacing or weak openings that may cause viewers to swipe away.

Do you store my video after analysis?

Results are kept for 24 hours so you can review them, then purged. We do not add analyzed videos to your media library automatically.

How long can the video be?

Up to 30 minutes on the free tier.

Is this better than guessing what the algorithm wants?

It gives concrete feedback on your actual video (transcript, cuts, on-screen text, and pacing) instead of generic tips.
