What’s the origin of the idea for your product?

The idea behind Polygraf AI Content Detector really came from a growing frustration and concern. With generative AI tools like ChatGPT and others becoming part of our daily workflows, it’s harder to know whether the content we were seeing online - or even using - is actually written by a human or quietly generated by AI.

Polygraf AI Content Detector was created to solve that exact problem, originally to identify AI generated online consumer reviews - but we quickly realized it was needed for all kinds of digital content. It’s not just about catching AI-written text - it’s about helping users understand where the content came from, whether it can be trusted, and why we think that - with real-time insights into reliability, origin and trustworthiness.

What problem is your product solving and how?

Distinguishing between human and AI-generated content, or simply identifying content provenance, has become increasingly challenging. Creators, educators, and businesses struggle to maintain the authenticity of their work while combating misinformation, plagiarism, and AI-driven humanization. The risks are real, and so are the potential damages to reputation, credibility and trust.

And that’s why we created Polygraf AI, to solve these problems - an AI content detector with an accuracy rate of over 98% that not only identifies AI-generated content, but also provides insights into its source and any potential manipulation. Our goal is to help you protect your work, reputation, and peace of mind, whether you’re writing, publishing, or verifying content.
