76/100Strong

It keeps moving and has real peaks, but the opening is the weak spot: first word at 4.8 s.

Fix first

  1. 1

    Start talking sooner — the first word lands at 4.8 s. Trim the lead-in so it lands under 1 s.

  2. 2

    Front-load the energy — the opening is calmer than the rest. Tease the peak at 0:08 in the first seconds.

Reels and Shorts, UGC videos, explainers and podcast clips (audio only works too), up to three minutes a read. Hindi, Hinglish or English: the timing checks listen to the voice, not the words.

How it works

Three steps, about a minute.

  1. 1

    Drop a clip

    Video or audio — mp4, mov, webm, mp3, wav. Anything longer than three minutes, you pick the section to read.

    Reading picture and sound…

  2. 2

    Every second is measured

    Cuts, motion, faces and expressions; speech, pace, pitch, music, beat and loudness. Each measurement is tested against clips with a known answer.

    Each fix with its frame, its second and the part it lifts, in the order a viewer meets the problems. The Craft score sits on top.

Hook

The first three seconds, checked one by one.

Does something happen at once? Does the first word land inside a second? Is there a face, movement, a sound? Is the opening as lively as the rest of the clip? Each check says what it measured — “first word at 4.8 s” — and what to do about it. Checks that cannot apply to a clip say so instead of counting against it.

Hold

Every second on one line — scrub it.

Intensity, picture change, speech and music, and the moments that pull attention back: a cut, a voice starting, a face arriving, a jump in loudness. Dead air and long still stretches are flagged where they happen. In the app the line is the player's scrubber; here, click anywhere on it.

Feel · sound

It listens as closely as it watches.

When the first word lands, how fast the talking is, how much the voice moves, where the music sits and how loud the mix plays after a platform evens it out. Podcasts and voice notes get the full read too — audio only, no picture needed.

Numbers from the same 22-second example. Loudness is measured the way YouTube and Spotify measure it.

Story

And a read of the story itself.

Seven plain questions about what is said and shown, each answered with the moment it is judging. Hook, Hold and Feel are measured from the file. Story is an AI read that lands about a minute later. The Craft score averages the parts a clip has.

  1. 1Promise

    Do the first 3 seconds say what the viewer gets by staying?

  2. 2Payoff

    Is that promise delivered?

  3. 3Clarity

    Is the point easy to follow on one watch?

  4. 4Specific

    A real example, number or demo — not a general claim?

  5. 5Surprise

    At least one moment that breaks expectation?

  6. 6Stakes

    A human reason to care?

  7. 7Ending

    Does it land, or trail off?

Who it is for

Built for the edit before you post.

Measured, tested, plain about its limits

Why the numbers hold up.

Tested against known answers

Every measurement is checked against clips built so the right answer is known. The checks are part of the product's test suite.

A metronome at 120 BPM
reads 120 BPM
A test tone, white noise, chords
read 0% speech
A camera panning across a still scene
reads as a camera move, not a moving subject
The same voice 6 dB quieter
reads the same pace, pitch and speech share

Same file, same measured score

Hook, Hold and Feel are measured, so the same file gets the same numbers every time. Story is an AI read at a fixed setting and only one of the parts averaged, so it cannot swing the score on its own.

Not a brain scan

The 3D brain in a result is a model of the measured signals — a way to see them, not a recording of anyone's brain.

Missing is never zero

No faces in a clip, no speech, or expression reading switched off: those checks are left out and named, never scored as a failure.

Questions

Asked, answered.

What is NeuroVidz?

A tool that reads a video or audio clip second by second — what is in the picture and what is in the sound — and scores how well it hooks, holds and moves a viewer, with the exact edits to make, each pinned to a timestamp.

How does it work?

It measures 39 signals every second — cuts, motion, faces and expressions, speech, pace, pitch, music, beat and loudness — and checks them against what keeps people watching: a fast start, no dead air, something new every few seconds, a clear high point. A language model then answers seven plain questions about the story. Every part of the score shows what it measured.

How is the score calculated?

Hook, Hold and Feel are measured from the file. Story is an AI read that lands about a minute later. The Craft score averages the parts a clip has, and each part is the average of its checks. Checks that cannot apply to your clip (no faces, no speech) are left out and named, never counted against it. The score describes how the clip is built; it does not promise views.

Is this a real brain scan or medically accurate?

No. Nothing is measured from anyone's brain. The score comes from the clip itself. The 3D brain in a result is a model of the measured signals, shown as a way to see them. None of it is medical, diagnostic or clinical.

Do you recognize people or store face data?

No. We detect faces only to read expression signals — we don't identify anyone or build facial-recognition templates, and face crops are discarded after processing. You can switch expression reading off in settings.

What happens to my video and data?

Your video is processed to produce the analysis and stored securely in your account. You stay in control — export or delete everything whenever you want.

What can I upload, and how long does it take?

Video or audio up to 400 MB (mp4, mov, webm, mp3, wav). Each read covers up to three minutes; drop a longer file and you pick which three minutes to read, right in the uploader. The edit plan lands in about a minute; the Story read follows about a minute later.

Can I export or delete my data?

Yes — anytime, from your account. Export downloads a copy of your data; delete permanently removes your videos and analyses.
