Frequently Asked Questions

Is this ethical? Is personality-based marketing manipulation? +
Think of it like learning Spanish. You're not manipulating Spanish speakers, you're meeting them where they are. COS has built-in guardrails: high-pressure manipulation tactics score poorly in our framework. We focus on connection, not deception.
How is COS different from asking ChatGPT to review my content? +
COS scores and rewrites copy too. That's not the difference. The difference is the measurement layer. ChatGPT pattern-matches to training data, so you have no idea how well its output maps to your buyers. COS constrains every rewrite to hit all five buyer personality types simultaneously, then scores the result against peer-reviewed frameworks. You get the fix plus the coverage number that proves it worked. ChatGPT can't produce that number because it has no psychological measurement layer.
Do you offer refunds if COS does not help? +
Every plan starts with a 7-day free trial. Cancel before it ends and you won't be charged. If you continue and aren't satisfied, email us within 30 days for a full refund. No questions asked.
Is my content private and secure? +
Your project content (Brand Voice, Personas, Files, Instructions) is encrypted at rest with a key your browser holds. We have no way to decrypt it. Chat and analysis run on the Anthropic Claude API; Anthropic's API terms prohibit using your prompts for training. Data is hosted in the U.S. See full Trust & Security details →
