Of all the resources and infrastructure that make World History Encyclopedia a reliable resource to readers worldwide, the most important is our Editorial Policy, which is closely implemented by our incredible editorial team. In 2025, we updated this policy to also address the use of AI: “In accordance with our AI Policy, all article submissions must be written by humans; we do not accept AI-generated or AI-assisted writing”.
As AI-based tools are developed and improved over time, identifying content written by or with AI has become increasingly difficult. This is why we are happy to announce we are partnering with Pangram Labs, the leading AI detector tool, to use their technology to assess the content we receive.
About Pangram
Pangram’s AI text detection model was developed by researchers and, according to studies, provides accuracy of 99%. Their research methods are openly published in favour of transparency, and their specific approach to development allows the platform to be improved over time.
You can read more about Pangram’s AI detection model on their website.
What does this mean for authors
Over 24% of text submissions we receive are from volunteer authors, who trust the World History Encyclopedia team to share their knowledge with millions of readers globally. We don’t take this lightly, and want to ensure that authors continue to experience a smooth and close relationship with our team.
Pangram will be directly connected to the tools used by our editors to review content submitted by authors. If, at any point, Pangram detects a high chance of AI use, the editor will contact the author and request them to review the piece.
While we understand that AI detectors can give false positives, our editorial team maintains a zero-tolerance policy towards AI-generated content. Authors whose work is repeatedly flagged for AI content will no longer be considered for publication.
What does this mean for readers
For readers, this partnership is another reinforcement of our commitment to trustworthy content.
As an organization, we continuously explore new ways to leverage AI and other types of technology to drive access to history education. When it comes to the content itself, though, readers can trust that our articles are human-written, not plagiarized, and held to high academic standards.
We’re grateful to Pangram for supporting our mission as a nonprofit organization, as well as the continuous engagement and support from volunteers, members and donors worldwide who contribute to making history accessible to everyone, everywhere.
