Korviq does one thing other tools cannot: it tells you what a viewer's brain is doing, second by second, while they watch your content. Here is the full process — the science, the pipeline, and why you can trust the numbers.
Simply share your video draft or file link with our team. That is all you do.
Email your video file or share link (Google Drive, Dropbox, Loom, etc.) directly to hello@trykorviq.xyz. We handle setting up the model, running the simulated audience pipeline, and compiling your retention guide.
Supported: MP4, MOV, and standard video links. Short-form edits (15–120s) yield the most actionable edit guides.

This is where Korviq is different from everything else. The Helix model is a state-of-the-art brain encoding transformer — trained on real fMRI brain scans from 25 human subjects watching video, audio and text.
Visual
Video frames
Motion, faces, objects, scene transitions, cuts.
Audio
Waveform
Tone, speech, music, pacing, silence, energy.
Language
Spoken words
Meaning, narrative, context, emotional valence.
points mapped on the human cortex — 10,242 per hemisphere — updated every second. Not just "the brain was engaged," but which region was active, how strongly, and why.
The output
A heat map of brain activation: a number at every cortical point, every second. High activation means the brain is fully captivated. Low means it is drifting. This data is computed mathematically. It is immutable — no AI agent can change a single number.

Every second is assigned a state based on the Helix model's activation score:
Simultaneously, Korviq timestamps every spoken word to the second. The report later knows not just when the brain dipped — but what was being said at that exact moment.
Not "the brain dropped around second 9." Instead: "the brain dropped at second 9, when you said '…' — here is why, and what to change." That specificity is what makes the recommendations actionable.
Once the Helix model completes, four AI agents work in sequence. Each has a single job. None can alter the brain data.
Agent 1 · The Neuro Doctor
Reads the raw activation scores and translates them into neuroscience language: which brain regions were most active each second, what those regions do (vision, language, emotion, memory), and what that means for how the viewer experienced that moment.
Agent 2 · The Content Analyst
Turns those notes into creator strategy: did the hook land in 3 seconds, the 3 strongest and 3 weakest moments (backed by peak and dip seconds), platform fit for Instagram, TikTok and Shorts, and your brain type.
Agent 3 · The Verifier
Fact-checks everything Agents 1 and 2 wrote against the actual Helix numbers. "Brain peaked at second 12" is verified against whether second 12 truly had high activation. If not, it is flagged and corrected. This is the hallucination guard.
Agent 4 · The Copywriter
Writes the copy you can paste: 2 hook rewrites from peak-activation regions, specific fixes for each drop zone, a CTA anchored to your peak moment, Instagram & TikTok captions, a thumbnail pick, and a next-video brief.
| Section | What you get |
|---|---|
| Cover | File name, duration, Retention Score |
| Attention Arc | Second-by-second viewer focus graph |
| Hook Verification | Did the opening 5 seconds capture attention or was it missed? |
| Content Profile | Visual / Auditory / Dialogue heavy / Face focused |
| Thumbnail Frame | Highest focus second, mapped to the best thumbnail frame |
| Platform Fit | Instagram, TikTok, and YouTube Shorts compatibility scores |
| Wins | 3 specific moments that held attention best, and why |
| Priorities | 3 specific pacing, cutting, and visual edits, ranked by impact |
| AI Copy | Captions, CTAs, and hook rewrites — ready to paste |
| Next Video Brief | Data-driven script and visual brief for your next piece |
The Helix Score
A single brain-engagement number for the whole video. Not a vanity metric — a compressed summary of your video's neural engagement profile.
A 7.2 with two clear drop zones is more useful than a 9.1 with no breakdown.
| Score | What it means |
|---|---|
| 9.0 – 10.0 | Exceptional — near-constant peak engagement |
| 8.0 – 8.9 | Strong — most moments land, a few gaps |
| 7.5 – 7.9 | Solid — good foundation, specific edits will lift it |
| 7.0 – 7.4 | Needs work — several attention drops to address |
The trust architecture
All activation numbers come from the Helix model — a pure mathematical step, no AI narrative.
The four agents receive those numbers as locked, immutable facts.
The Verifier agent cross-checks every claim against those facts.
A final automated scan corrects any timestamp that does not match real data.
The science is upstream of the language. Every sentence is a translation of a real number, not an invention.
The simulation
Every video we analyze is run through a stateful cohort model of 100 simulated viewer agents. The simulation replicates real short-form video platform behavior step-by-step:
| Funnel Stage | What it evaluates |
|---|---|
| Stage 1: Followers | Simulates 50 follower agents watching your video. Evaluates core niche retention and ghost scroll rate (viewers who scroll within 2s). |
| Algorithm Gate | Checks if the completion rate hits the platform gate threshold (Instagram 55%, TikTok 65%, Shorts 50%). If a gate fails, cold distribution is locked. |
| Stage 2: Cold Push | Serves your content to 50 cold-audience agents outside your niche, simulating initial viral push dynamics. |
| Social Cascade | Models 7 rounds of sharing network interaction (DMs, tags, group chats) to compute the viral K-factor and project 7-day impressions. |
Hook check
The first 5 seconds are the most critical moment of your content. If your opening seconds fail to hook viewers, they scroll past before your message lands.
Hook Missed Alert
Our simulation checks the average viewer attention scores during the first 5 seconds. If the score falls below a 0.65 threshold, the model flags a critical alert: Hook Missed. The guide will identify the exact second of drop-off and provide 2 optimized hook rewrites directly from Wernicke and visual cortex peaks to recover attention.
