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. SEMalytics has built-in guardrails: high-pressure manipulation tactics score poorly in our framework. We focus on connection, not deception.
How is SEMalytics different from asking ChatGPT to review my content? +
ChatGPT can rewrite your copy. It can’t tell you how many of your five buyer types the rewrite reaches, because it has no measurement layer. SEMalytics scores the copy against five buyer personality types, shows which ones you lose, and scores the fix so you can see the number move.
Why not just edit the AI draft myself? +
You should. Every AI draft needs an edit. The hard part is knowing what to change. A draft can read fine and still miss some of your buyers. SEMalytics scores the draft against five buyer personality types, shows which ones it misses, and points to the lines to fix, so your edit has a target.
Do you offer refunds if SEMalytics 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 commercial terms prohibit using your prompts for training (last verified September 2026). Data is hosted in the U.S. See full Trust & Security details →

Most AI copy reaches 40–50% of buyer personality types

SEMalytics shows you your number before you publish, and the lines to fix to raise it. Coverage measures how many buyer types your copy reaches, not how many will buy. (Coverage figures reflect patterns in SEMalytics analyses; proprietary data, not a published statistic.)
