BuiltByHuman is a Chrome extension designed to detect AI-generated code on any website with a simple click. This tool provides users with an instant authorship report, featuring a probability score ranging from 0 to 100 that indicates the likelihood of AI involvement in the content. The extension is particularly useful for freelancers, agencies, educators, and anyone interested in verifying the authenticity of web content.

The report generated includes a breakdown of human versus AI signals, along with code evidence snippets that support the findings. Users can easily share the report via a link, making it convenient for collaboration or verification purposes. The free plan allows for up to three scans per month, while a pro plan is also available for more extensive use.
