COS — Content Optimization System
Score your content before it ships. 8 dimensions. 860+ peer-reviewed papers. No guessing.
Most content tools optimize one axis. Grammarly checks grammar. Jasper writes without audience grounding. SEMrush ranks keywords. COS scores what you write — against 8 dimensions grounded in 860+ peer-reviewed papers on personality psychology and persuasion science. Paste a draft, paste a URL, or analyze before publish. See where it lands before it goes out.
You paste a sales email, a LinkedIn post, an ad, or a landing page. You name the audience (a job title is enough — COS infers the rest). COS returns four framework scores, the specific rewrites that would move them, and a one-line lead insight you can act on right now. Analyses export as PDF, DOCX, Markdown, CSV, or plain text.
The four frameworks
- Engagement. Emotional triggers that drive response — impact, novelty, relevance, social proof, urgency. Scored against the engagement psychology literature.
- OCEAN personality fit. Whether the copy matches how your audience processes information across the Big Five dimensions. A high-Conscientiousness buyer needs specifics before benefits land. A high-Agreeableness buyer needs peer validation. COS scores all five and flags which dimensions your draft skips.
- Strategic clarity. Whether the message lines up with the business outcome you are chasing. Value prop, differentiation, call to action — coherent or contradicting itself.
- Cognitive framing. Whether the framing lowers the reader's resistance or raises it. Power positioning, frame discipline, identity-safety.
Most copy fails on one or two dimensions silently — the targeting was right, the spend was right, the copy just did not fit. COS identifies the gap before launch, not after the campaign debrief.
Frequently asked questions
What is COS?
COS is a website content monitor that scores marketing and sales copy across 8 dimensions — Engagement, Audience Fit, Strategic Clarity, Framing Strategy, SEO Health, AEO Readiness, Copy Quality, and Persuasion Fit — and returns specific rewrites for each weakness it finds, grounded in 860+ peer-reviewed papers.
How is COS different from Grammarly, Jasper, or SEMrush?
Grammarly checks grammar. Jasper drafts generic AI copy. SEMrush ranks keywords. COS scores your content before it ships — 8 dimensions grounded in 860+ peer-reviewed papers — so you know whether your copy fits your buyer's personality profile before you send it.
What kinds of content does COS analyze?
Sales emails, cold outreach, LinkedIn posts, Facebook and Google ad copy, landing pages, and sales scripts. Anything where a specific human needs to read it and respond.
Do I need to define my audience before analyzing?
No. You can analyze with just the content. Providing an audience profile — a job title, a personality description, or a named buyer — sharpens the recommendations significantly.
Does COS use AI?
Yes. Frameworks are grounded in peer-reviewed psychology and decision science research; per-message scoring is performed by Claude. Research rigor with per-message specificity, in one pass.
Can I export my analysis?
Yes. PDF, DOCX, Markdown, CSV, or plain text. The export includes scores, top strengths, before-and-after rewrites for each fix, and the original content for archive.
Is there a free tier?
Yes. Free analyses let you score your top drafts before subscribing. The paid plans (Solo, Team, Enterprise) add higher usage and audience profiling for teams running COS as a standard pre-launch step.
