Performance Scoring

Every major performance signal, scored in one report.

Your video is scored across the five dimensions that determine whether viewers keep watching: hook strength, pacing, audio quality, visual clarity, and engagement potential. Each score comes with specific notes on what's strong, what's weak, and what deserves attention first.

  • Hook score with rewritten alternatives
  • Pacing analysis with dead-spot detection
  • Audio quality and delivery evaluation
  • Visual clarity and text readability check
  • Overall engagement grade with priority fixes

Retention Prediction

Find the moments most likely to lose your audience.

A predicted second-by-second retention curve shows where attention weakens, where energy dips, and which moments are most likely to cause viewers to scroll away. Instead of a single watch-time number, you get a practical roadmap for keeping more people watching longer.

  • Second-by-second retention prediction
  • Drop-off timestamps with specific reasons
  • Signals tied to hook, pacing, and clarity
  • Comparison against platform benchmarks

Instant Fixes

Not just feedback. Specific fixes you can actually use.

A report is only useful if it helps you make better content. Retensis doesn't stop at diagnosis — it generates rewritten hooks, better framing suggestions, caption alternatives, and clear next actions so you can improve your packaging immediately instead of just reading a score and moving on.

Beyond Analytics

Platform analytics tell you what happened. This shows you why.

TikTok, YouTube, and Instagram analytics are valuable, but they arrive after publish and stay high-level — views, likes, average watch time. AI Video Analysis explains the actual creative reasons a video may struggle, early enough to fix those weak points before they repeat in your next upload.

It identifies the creative elements statistically associated with viewer drop-offs — weak hooks, dead air, pacing dips — and maps them to specific timestamps so you can see where attention is most at risk.
