Features
Hook Strength Score
Rates the opening three seconds on motion, audio intensity, and what the first frame actually shows a scrolling viewer.
Watch-Through Estimate
An estimate of how much of the clip a first-time viewer is likely to sit through, so a weak clip gets fixed instead of posted and forgotten.
Trim Suggestions
Points at dead frames at the head and tail and proposes exact in and out points, which is usually the single cheapest fix available.
Caption Placement Check
Flags captions sitting on a face or crowding the safe area, where a platform's own UI will cover them.
How It Works
Bring in a clip
Use a clip AutoClip generated or drop in your own — TikTok, Reels, or Shorts dimensions all work.
AutoClip scores the opening
It looks at the first seconds, the audio, where the captions sit, and how the clip is shaped overall, then explains each part of the score.
Apply the fix and post
Take the trim or the caption adjustment, re-render, and post. Most weak clips are two seconds of dead air away from being fine.
Frequently Asked Questions
What makes a good clip hook?
Something has to be unresolved within about two seconds — a reaction you want explained, a claim you want to argue with, motion that implies what's coming. Static openers, silent intros, and slow wind-ups lose the viewer before the good part arrives.
How reliable is the watch-through estimate?
Treat it as a relative signal, not a forecast. It's useful for ranking your own clips against each other and catching the obviously broken ones before they go out — it can't account for the topic, the account posting it, or what the feed is rewarding that week.
Does the hook optimizer work for gaming clips?
Yes, and gaming is where it earns the most: the common failure is burying the play behind six seconds of setup. It checks whether the action is front-loaded, whether captions cover the part of the screen that matters, and whether the length sits in the 15–45 second band where short-form completion holds up.
