"Your sales team spends 12 hours a week on admin. Our clients cut that to 3. Here is how one team did it in 30 days."

After: Coverage 91%. Numbers activate analytical buyers. The timeline anchors cautious ones. "Team" engages relationship-oriented readers. COS generated this — and scored it.

Frequently Asked Questions

Is this ethical? Is personality-based marketing manipulation? +
Think of it like learning Spanish to communicate with Spanish speakers—you are not manipulating them, you are adapting to their communication style. COS has built-in ethical guardrails: we help you communicate more effectively, not deceive. High-pressure manipulation tactics actually score poorly in our Cognitive Autonomy framework.
How is COS different from asking ChatGPT to review my content? +
COS generates copy too — that's not the difference. The difference is how. ChatGPT pattern-matches to training data, which means the output reflects the personality profile of whoever wrote similar content in the training set — you have no idea who that was or how well it matches your buyers. COS constrains generation to activate specific psychological triggers for all five buyer personality types simultaneously, then scores the output. You get copy plus the coverage number that proves it worked. ChatGPT can't produce that number because it has no psychological targeting architecture to measure.
Do you offer refunds if COS does not help? +
Every plan starts with a 7-day free trial. Cancel anytime during the trial and you will not be charged. If you continue and are not satisfied, email us within 30 days for a full refund—no questions asked.
Is my content private and secure? +
Your copy stays private. Analysis happens in real-time; we never store, share, or use your content for training. Enterprise plans include additional security options and SSO.
