LucidLab analyses your video, audio, or script and tells you exactly what captures attention, triggers emotion, and drives memory — second by second, before you publish.
Two cuts of the same reel. Two thumbnails. Two hook variations. Don't guess which one will perform — compare them neurally and post the winner.
Win pitches with proof. Compare creative variants before clients see them, cut revision cycles, and deliver the version backed by brain data — not gut feel.
Make your media spend go further. Compare campaign variants, benchmark what actually drives emotional connection, and ship the one your audience's brain already prefers.
Upload a single video for analysis, or upload two to compare. Tell us your intent, and LucidLab tells you which variant your audience's brain already prefers — and why.
Drop in one or two videos — a hook, a cut, an ad variant, up to 60 seconds each. We also accept audio and text.
A line is enough. Who's the audience, what's the goal, where will it live? We use this to weight the six dimensions in the way that matters for your campaign.
Attention, Arousal, Emotional Reaction, Visual Appeal, Cognitive Load, and Memory — scored per second, the same way a real brain processes your content.
A clear verdict with the reasoning behind it, plus written guidance on what to trim, re-cut, or re-open on the losing variant before you publish.
Each dimension maps to a specific network of brain regions — giving you neuroscience-grade precision on exactly how your audience's brain responds, second by second.
Are viewers locked in or mentally checking out? See the exact second you lose them — and fix it before anyone watches.
Does your content energise or bore? High arousal moments keep people watching. Know where yours are and how to create more.
Is your message landing emotionally or just intellectually? Emotion drives shares, saves, and action. See when yours activates — and when it goes flat.
Are your visuals pulling people in or pushing them away? Identify the frames that reward the eye — and the ones that quietly kill engagement.
Is your content easy to follow or mentally exhausting? When the brain works too hard, it switches off. Find the moments where your message becomes too heavy.
Will people remember your content an hour later? Most won't. See which moments actually stick — and build more of them into every video.
We ran this motivational short through LucidLab. The creator thinks they know what the hook is. The brain data tells a completely different story.
Shaded regions indicate the three narrative phases. Dashed vertical line marks the all-6 peak alignment.
Strong visuals pull viewers in, but the emotional connection hasn't formed yet. The brain is watching, not feeling.
The stats section causes a sharp drop in brain engagement. Abstract numbers switch viewers into passive mode — they're processing, not connecting.
All 6 dimensions climb together. The message becomes personal and all brain signals align — this is when the content truly lands.
"good ones in the manner that I perceive" — this is the pivot where statistics become personal meaning. Not the opener.
"so little time, it feels stupid to do things because others want" — this is the neurally validated core message. Not the opening line.
Visuals drop sharply but voice delivery keeps people watching. A stronger visual here could amplify what the words are already doing.
"When we have so little time" — attention, emotion, memory and arousal all peak together. This is the rarest signal. This is the real hook.
Creators think the hook is "I'm 39 years old." The brain says it's "so little time, it feels stupid." LucidLab finds the real hook.
The stats section (seg 7–26) neurally disengages the audience. A concrete edit suggestion — before a single person watches.
"Nobody is" spikes Attention but leaves emotion unresolved. Memory drops sharpest at the end. The video closes on a thought, not a feeling.
LucidLab is powered by models trained on real human brain data from human subjects watching naturalistic video. No guesswork. No surveys. No panels.
No guesswork. No panels. No surveys. Just brain data that tells you what works.
Cut three rounds of revision on a recent auto campaign. What took us two weeks of focus groups, LucidLab surfaced in five minutes.
Each credit analyses 30 seconds of video. A 60-second clip uses 2 credits. A two-video comparison uses credits per video.
