A free retention check for one published short video: paste your average percentage viewed and get a PASS / REWORK / REBUILD verdict with the threshold shown, plus the single biggest retention leak named and one concrete fix.
Paste each new Shorts topic and get a feed-ready title, a 3-second hook, and marked retention beats at 15s and 30s so the script keeps paying off. It never claims YouTube Analytics or view-count data.
For a short you already posted. Send the video plus a screenshot of its retention graph (or your average % viewed) and get the curve redrawn with the drop-offs marked, the frame on screen at each drop, every leak ranked, a cut list with the new target length, and a verdict printed next to its threshold.
Turn video scripts into structured retention audits — map hook failures, desertion windows, and re-engagement fixes using attention psychology.
You already wrote a hook — spoken line and/or on-screen text. Paste it with your platform (TikTok / Reels / Shorts) and get a 0-10 score on 4 things that decide the first 3 seconds: clarity, curiosity gap, specificity, and pace. Each score gets a one-line reason, plus the single biggest fix and one rewritten version. This only grades a hook you already have — it doesn't generate new hook ideas or a script. For 5+ hooks and a full script from a topic, that's a different agent (Hook Lab).
A free single-file tool that tells you whether a short-form script fits your target length before you record it. Open the HTML in any browser - no install, no signup, no API key, no coding tool of any kind. Paste your script and get the estimated spoken length, a per-line breakdown marking your first cuts, a hook-length check, a warning for lines too long to read as captions, and a stopwatch that measures your own pace and recalibrates to it. Runs offline; your script is never uploaded.
Your script runs long and you are recording today. Open one HTML file in any browser - no install, no signup, no API key, no coding tool of any kind - and every line becomes a row you can keep, tighten or cut while the running total moves. It names the lines that would get you to your target, strips stock filler and reports what it cost, finds the block eating the overrun, checks a hook against the first seconds, and exports the recut script, caption cards and a printable shot list. Offline.
Takes any piece of writing — an email, a Slack message, a report, a doc, a cover letter — and tightens it up: cuts filler, kills unnecessary hedging ("I just think," "sort of," "kind of"), removes throat-clearing openers, swaps vague words for concrete ones, varies sentence rhythm, and nudges passive voice to active where it's just habit rather than a deliberate choice.
