Second-by-second retention forecast for your video's first 6 seconds — which seconds bleed, why, and 3 ranked hook fixes. Every prediction goes on an auditable ledger.
Paste your Shorts topic and get a feed-ready title, a 3-second hook, and a script with retention beats at 15s and 30s — so viewers stay past the swipe zone.
Your hook decides in 3 seconds. We make those 3 seconds count.
Audits your short-form script with four reviewer lenses and returns a keep/tighten/cut beat table, 3 labeled alternative hooks and a prioritized fix list.
Hands-on prompt engineering and LLM evaluation. Built around a diagnose-then-ship loop: forensic transcript critique ▎ that names the exact failure mode, paired with a fixer that produces complete, deployment-ready rewrites — not ▎ vague advice.
Analyzes your video hook or script, predicts 1-to-6-second retention, exposes drop-off points, and instantly generates a fully rewritten, high-retention script version.
Paste one published short's script plus its real analytics and get a retention autopsy of that exact video: a self-contained HTML report with the drop-off mapped second by second, a PASS / REWORK / REBUILD verdict against printed thresholds, a shot-by-shot cut list, and five hook variants.
Turn video scripts into structured retention audits — map hook failures, desertion windows, and re-engagement fixes using attention psychology.
