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 ChatGPT with personality prompts? +
ChatGPT can generate personality-adapted content if you know what to prompt for. But COS analyzes your existing content (not generating new), shows you exactly which personality types you are missing with quantified scores, uses four complementary psychology frameworks (not one), and preserves your authentic voice instead of replacing it.
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.

Your Prospects Are Not Ignoring Your Message

They are processing it through a personality filter you did not design for. COS shows you that filter — in 60 seconds — so you can write copy that passes through it instead of bouncing off.
