TikTok Video Analyzer

Paste any TikTok URL (or its hook) and get an instant AI breakdown: virality score, hook strength, retention risks and concrete fixes.

Provide at least a URL OR a hook/caption.

This free TikTok video analyzer scores any TikTok across the 4 factors that decide reach on the For You page: hook strength in the first 1-3 seconds, expected watch time and completion rate, share and save potential, and how well the video fits current trends in its niche. You get a 0-100 virality score plus a prioritized list of fixes you can apply before posting.

It works on your own videos and on anyone else's. Paste a competitor's TikTok to reverse engineer why it took off, or paste your draft caption and hook to pressure-test an idea before you shoot it. You can also switch to the account tab and audit the last 30 posts of any public TikTok account to see its posting consistency and viral outlier rate.

How does the TikTok video analyzer work?+

It evaluates the hook, expected retention, share potential and trend fit of the video, then computes an overall virality score out of 100 with prioritized fixes. The model is tuned for short-form signals: first-seconds hook, pacing, completion rate drivers and share triggers.

Can I analyze a TikTok that is not mine?+

Yes. Paste any public TikTok URL. Analyzing competitor videos is the fastest way to understand what the algorithm is rewarding in your niche right now.

What makes a TikTok go viral in 2026?+

Completion rate and re-watches carry the most algorithmic weight, followed by shares and saves. That is why the analyzer scores your hook and retention first: if viewers scroll in the first 2 seconds, nothing else matters.

Can I analyze a whole TikTok account?+

Yes. The account tab audits the last 30 posts of any public TikTok account and returns an overall viral score, posting consistency, viral outlier rate and the top 3 posts. Limit: 1 account per day.

Is the TikTok analyzer really free?+

Yes, no signup required. If you want continuous viral detection across your whole niche with ready-to-shoot content briefs, that is what Viral Manager does (7-day free trial).
