The short version: Pax is an awareness tool. It analyzes content for patterns it is programmed to detect and surfaces those findings to help you think more clearly. It is not an authority, a fact-checker, or a decision-maker. You are always in control. Pax raises questions — you answer them.
By downloading, installing, or using the Pax — Personal Cognitive Firewall browser extension or mobile app (the "Product") or visiting paxpcf.com (the "Site"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Product or the Site.
These Terms apply to all users of the Product and the Site. Pax is developed and operated by an independent individual developer, not a registered business entity.
Pax is an assistive awareness tool. It analyzes the visible text content of web pages and identifies patterns that are consistent with known influence and manipulation techniques. It surfaces these findings to the user to raise awareness — nothing more and nothing less. Pax is programmed to detect specific patterns. When those patterns appear, Pax flags them. It does not render editorial judgment, determine truth or falsehood, or evaluate the intent of any author, organization, or publisher.
Pax is not any of the following:
Pax detects patterns. Patterns are not proof. The presence of a detected pattern in content is an observation — an invitation to think more carefully — not a conclusion.
Pax is programmed to recognize fifteen categories of influence patterns commonly associated with psychological manipulation, emotional persuasion, social pressure, and information distortion. These categories include, but are not limited to: fear framing, false dilemmas, tribal acceptance appeals, PSYOP signals, sycophancy, fake authority, emotional manipulation, and information manipulation.
When Pax analyzes a page, it sends the visible text to the Anthropic Claude AI model — either via your personal API key or via a secure Pax proxy server depending on your subscription type. The AI evaluates the content against programmed pattern categories and returns findings. Pax then displays those findings to you in the form of an influence score and plain-language explanations.
Important: The influence score and pattern detections produced by Pax are the output of an AI language model analyzing text for programmed patterns. They are probabilistic assessments, not definitive facts. The same content may produce different results under different conditions, and Pax may miss patterns or detect patterns where a human reader might disagree.
Pax's findings are intended solely to raise your awareness and prompt your own independent thinking. They are not intended to be, and should not be treated as, authoritative conclusions about any piece of content, any author, or any organization.
Pax is provided for informational and awareness purposes only. You are solely responsible for any decisions you make based on information provided by Pax. The developer of Pax shall not be held liable for any loss, harm, damage, or negative outcome — direct or indirect — arising from your use of or reliance on Pax's analysis, findings, scores, or any other output produced by the Product.
This includes but is not limited to:
Pax raises awareness. You make decisions. That distinction is fundamental to how this tool is designed and intended to be used.
Pax uses artificial intelligence to detect patterns. AI is not infallible. Pax may produce results that are incomplete, imprecise, or that a reasonable person might disagree with. Factors that may affect accuracy include the complexity of the content being analyzed, the style and context of the writing, the limitations of the underlying AI model, and the inherently subjective nature of identifying influence techniques in natural language.
No influence score produced by Pax should be interpreted as a precise measurement. Scores are relative indicators designed to prompt reflection — not absolute ratings of any piece of content's credibility, bias, or intent.
The developer makes no warranty, express or implied, regarding the accuracy, completeness, reliability, or fitness for any particular purpose of Pax's output.
Pax does not endorse, recommend, or condemn any news organization, publication, website, author, political party, government, product, or viewpoint. The detection of a pattern in content produced by any source is not an editorial statement by Pax or its developer about that source.
Similarly, the absence of a detected pattern in content from any source does not constitute an endorsement, validation, or recommendation of that source by Pax or its developer.
Pax is a politically neutral tool. It is designed to detect influence patterns regardless of the political orientation, nationality, or affiliation of the source being analyzed.
