The leading RSI algo for content creation

Build your brand’s viral formula.

Scan every second of your video, up to 3 minutes, and see exactly where viewers drop off. Fix it before you publish, so every post and every ad dollar keeps people watching.

  • Every second, start to finish. Up to 180 seconds, not just the hook.
  • Your viral formula. Learn what keeps your audience watching, video after video.
  • Higher ROAS. Put your ad budget behind creatives that hold attention.

We watch. You fix. You publish.

Shorts, Reels, TikTok and video ads, up to 180 seconds.

Real report · demo clip “dead_hold” · every second scanned Level 1 · Expert read
Hook strength 100/100 Great opening, but viewers still leave at 4 s
first 3 s likely swipe strong hook recovers 0 s 15 s
  1. likely swipe 4.0–7.5 s · A still shot with flat audio and no setup. Cut it shorter, or add tension in the sound.

Real output from the internal demo. The same scan runs across the whole video, up to 180 s.

Retention is the formula. ROAS is the payoff.

The videos that win keep people watching to the end. We help you find what does that for your brand, and make every post and every paid campaign work harder.

For your brand

Develop your viral formula

Every video you scan shows what holds your audience and what loses them: openings, pacing, pauses, endings. Over time that becomes a playbook you can repeat, built from your own content.

  • Spot the patterns behind your best performers
  • Repeat what works, retire what doesn’t
  • Keep the whole team on the same formula
For your campaigns

Boost return on ad spend

A creative that loses viewers early wastes budget. Fix the drop-off points before launch, and spend behind the versions that hold attention to the end.

  • Check every ad creative before it goes live
  • Pick the strongest version to put budget behind
  • Stop paying for views that leave at second four

Studio tells you where people left. After it’s too late.

Every second

Viewers can leave at any moment, not only in the hook. We scan the whole video, up to 3 minutes, and give the opening extra attention.

Stillness

A pause isn’t always bad. Some build anticipation; others just stall. We tell them apart.

Before, not after

Fix the weak moments while you can still edit, not after the video has already lost its audience.

How it works

  1. 1

    Upload

    Drop in the video or ad creative before it goes live. Up to 180 seconds, mp4, mov, webm or mkv.

  2. 2

    We read every second

    From the first frame to the last, moment by moment, through our three-level approach.

  3. 3

    You get the report

    Hook score, drop-off curve, flagged moments with a reason, and the top three fixes. About half a minute in the demo.

  4. 4

    Publish, then compare

    Once your video has had time to gather views, bring back its real retention. Your next prediction gets sharper.

One video. Three levels of insight.

No single method is right on day one and still right at scale. So we combined three. Each level reads the same video at a different depth, and together they get sharper every time you publish.

01Live

Expert read

Reads your video the way a seasoned editor would.

  • Ready from the first upload
  • Pinpoints the moments that lose viewers
  • Explains why, and what to change
02Beta

Audience simulation

Predicts how an audience will watch, before anyone has.

  • A full retention curve, not just warnings
  • An honest range, not a single guess
  • Learns from every video you publish
03In development

Learned retention

Our own model, built from real audience behaviour.

  • The most precise curve
  • Grows with the data behind it
  • Earns its place before it’s switched on

Why three levels work better together

Always useful

You get a clear read from the very first video, before there is any history to learn from.

Always improving

Every published video makes the next prediction more accurate, starting with your own channel.

One shared picture

All three levels work from the same understanding of your video, so their findings line up.

Proven before trusted

A deeper level runs quietly alongside and has to prove itself before it takes over.

Proprietary approach. Methods and models are confidential.

The leading RSI algo for content creation.

RSI = recursive self-improvement. Every video you make teaches the system, and the system makes your next video better. Results flow back into every level, so each turn of the loop starts smarter than the last. It compounds.

The recursive loop: create, predict, publish and learn around three levels, spiralling in toward a better next video 01 · Expert read 02 · Audience simulation 03 · Learned retention Create Predict Publish Learn Your next video
Illustrative. Every turn feeds real results back in.
  1. Create

    You make a video or an ad creative.

  2. Predict

    Every second is read and a prediction is recorded before it goes live.

  3. Publish

    It goes out. About two days later, the real audience result comes back.

  4. Learn

    The result feeds the levels. The next prediction, and the next video, start smarter.

01

Sets the starting line. A strong read from the very first upload.

02

Sharpens with every result. Each published video tunes the next prediction.

03

Grows from what the loop collects. More results, more precision.

Your viral formula isn’t written once. It’s discovered, tested and refined, loop after loop.

What you get

Hook strength, 0–100

How likely people are to stay past the first 3 seconds, with what weakens it.

Full-length retention curve

Risk or predicted retention for every moment of the video, up to 180 seconds, start to finish.

Flagged moments

Each with a severity, watch risk likely swipe, and a reason you can act on.

Fixes that pay off

Plain-language “why” and “fix” for the moments that cost the most viewers, wherever they are in the video.

Not every pause is a problem

Two videos with the same 5-second pause. Most tools flag both. We only flag the one that loses viewers.

risk Flagged: nothing gives the viewer a reason to wait.

Choose your level

In the app, Settings → Prediction engine has one switch per level. Only one is on at a time. Try it below.

Rules + AI judge Default

Level 1, the expert read. Risk curve, hook score, flagged moments and fixes.

Simulation Beta

Level 2, audience simulation. A predicted retention curve with a range, sharper after you publish.

Custom model In development

Level 3, learned retention. In development; shown greyed out in the app for now.

How to test it

The app runs as a local demo for now. This page explains it; testing happens in the demo.

  1. Get into the demo

    Ask the team for a session on the demo machine, or run it yourself: make demo, then open localhost:3000.

  2. Sign in

    Enter your email and click the link (in the demo, the team reads it from the server log). No passwords.

  3. Try the four demo clips

    • weak_hook → low hook score, early “likely swipe”.
    • strong_hook → strong hook, few or no moments.
    • dead_hold → the still shot is flagged.
    • suspense_hold → the same still is not flagged.
  4. Try your own video

    Anything you’d post: up to 3 minutes. Compare the flags with your own instinct.

  5. Switch levels

    Settings → Prediction engine. Turn on Simulation (Level 2) and analyse the same clip again.

Common questions

Which videos does it work on?

Videos up to 180 seconds: YouTube Shorts, Reels, TikTok and short video ads. You upload the file; it doesn’t post anything for you.

Does it only look at the first few seconds?

No. It scans every second of the video, up to 3 minutes, and flags drop-off points wherever they happen. The opening gets extra attention because that’s where many viewers decide.

How does this help ROAS?

Paid views that drop off early don’t deliver your message. Checking creatives before launch lets you fix those moments and put budget behind the versions that hold attention. We don’t promise a number; we help you spend on stronger creatives.

Is the curve a real prediction of my views?

It predicts where viewers are likely to leave, not how many views you’ll get. Level 1 shows risk. Level 2 shows a predicted retention curve with a range, which gets sharper as real results come back.

How long does an analysis take?

About half a minute per clip on the demo laptop. Longer videos take longer.

What happens to my video?

In the internal demo it stays on the demo machine, except when it’s sent to an AI service for analysis.

What isn’t ready yet?

Level 3, connecting a YouTube channel, and a public sign-up. This is an internal preview.

Keep them watching. Every second.
