Built on Research, Not Opinions
SEMalytics exists because marketing content decisions shouldn't be made on gut instinct when the science already tells you what works.
Our Mission: Make Buyer Psychology Actionable
Decades of peer-reviewed research in personality psychology, behavioral economics, and communication science tell us exactly why some messages land and others don't. That research has been sitting in academic journals, inaccessible to the marketers and salespeople who need it most.
COS changes that. We translate the science into a tool that analyzes any piece of content and tells you which buyer personality types it connects with — and exactly how to improve coverage for the ones it misses.
The goal isn't to replace good writing. It's to give good writers the one piece of information they've never had: proof that their copy actually works before they publish it.

The Problem We're Solving
Generic AI Writes for Nobody
AI writing tools generate content by pattern-matching to training data. That training data reflects whoever wrote similar content before — you have no idea whose personality profile it targets. The result is copy that's statistically average, which means it resonates with no one in particular.
Gut Instinct Isn't Scalable
Experienced marketers develop intuition about what resonates — but it takes years to build, doesn't transfer, and can't be audited. When a campaign misses, there's no systematic way to understand why. A/B testing tells you what won, not why, and not how to fix the loser.
Buyers Are Psychologically Diverse
Research consistently shows that the five OCEAN personality dimensions predict communication preferences, purchase behavior, and response to persuasion strategies. Any given audience contains all five types. Content that only activates one or two leaves the rest cold — but you never knew it was happening.
How COS Works
COS analyzes content across four interlocking frameworks, each grounded in a different body of research. Every submission gets scored on all four simultaneously.
Personality Analysis (OCEAN)
Scores content against all five Big Five personality dimensions — Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism. Identifies which buyer types the message activates and which it misses, with specific rewrites for each gap.
Engagement Analysis
Evaluates emotional triggers, narrative structure, and motivational levers across the content. Identifies which engagement patterns are active and which are absent — each mapped to research on persuasion psychology and behavioral activation.
Framing Strategy Analysis
Analyzes cognitive framing — how the message positions choices, anchors value, and shapes how buyers perceive the stakes. Based on decision science research including prospect theory, anchoring effects, and reference point framing.
Strategic Clarity Analysis
Evaluates coherence between the message and its stated goal. Flags cases where the framing, call to action, or audience signals work against each other — common in copy that was optimized for tone at the expense of direction.
The Team
David built SEMalytics after spending years watching smart marketing teams produce content that failed to land — not because the writing was bad, but because no one had a way to measure whether it reached the actual humans on the other end. The tools available measured grammar, SEO keywords, and readability. None of them measured buyer psychology.
COS is the tool he wished existed: a system that translates academic research on personality and persuasion into something a marketer can use before they hit publish. The analytical framework draws on 860+ peer-reviewed studies, distilled into scoring rubrics that give content teams a number they can act on.
SEMalytics is an independent, bootstrapped company. No outside investors means the product roadmap is driven entirely by what actually helps customers write better — not by growth metrics that have nothing to do with quality.
How We Work
Research-First
Every scoring dimension in COS is anchored to peer-reviewed research. We don't add a feature unless there's a body of evidence supporting what it measures. The science page documents the academic foundation.
Privacy by Design
Your content is analyzed in real-time and never stored, shared, or used to train models. We built the product the way we'd want our own content handled — which is to say, privately.
Ethical Guardrails
COS is built to help you communicate more effectively, not to manipulate. High-pressure tactics and deceptive framing score poorly by design. The Cognitive Autonomy framework exists specifically to flag and penalize them.
