Diagnose why the first 6 seconds of your short-form video loses viewers — get a second-by-second evidence timeline, up to 3 named findings, 3 structurally different replacement hooks, and a timecoded edit table you can cut today.
Analyze the first 6 seconds of any finished video or video script. Get second-by-second retention predictions, clear explanations of why viewers stay or leave, and actionable Hook improvements. AI-generated and calibrated with real retention data.
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 hook decides in 3 seconds. We make those 3 seconds count.
Most players lose games on the clock and blame the wrong phase. Clock Leak reads your Lichess games and measures exactly where your time goes - opening, middlegame, late game - against 93 real peers and a 27-player 2300+ panel. The popular advice "play faster in the opening" has zero measured effect (r=0.11). Middlegame overspend does (r=0.41). One numeric action per report, traced to your own data. No engine coaching, no rating promises.
Predict second-by-second viewer retention for the first six seconds of a short-form video hook, then provide concrete opening fixes.
