Alternate History AI is an educational history simulation. Scenarios explore how decisions, institutions, conflicts, and social conditions shaped historical outcomes. The site does not endorse conquest, slavery, discrimination, political violence, war crimes, terrorism, genocide, or harm against any person or group. Sensitive subjects are included for historical analysis and critical thinking only.

Our Approach
Every article and scenario on AltHistAI.com is researched against peer-reviewed academic sources, reviewed by human editors, and written to the E-E-A-T standard of Experience, Expertise, Authority, and Trust. We combine AI-assisted drafting with editorial oversight to produce counterfactual analysis that is historically grounded, analytically rigorous, and responsibly framed.
Sensitive historical topics — slavery, genocide, colonialism, political violence — are handled with care. We do not glorify perpetrators of atrocities, and we centre the structural and institutional forces that shaped historical outcomes alongside the roles of individuals.

How It Works
Alternate History AI is powered by three integrated capabilities that work together to create a rigorous, educational what-if simulation experience:
Every scenario is grounded in peer-reviewed scholarship. We analyse cause-and-effect chains, structural forces, and the genuine points of historical contingency before any simulation begins.
Users choose divergence points and make decisions that branch history. Choices cascade across multiple simulation cycles, teaching path dependency, unintended consequences, and the butterfly effect.
Advanced AI language models generate historically plausible consequences within a structured scenario framework, combined with human editorial review and responsible content standards.
