Methodology & Accuracy — How AskHistoryAI Is Made and Verified

AskHistoryAI is an interactive timeline of roughly 13.8 billion years — from the Big Bang to the dawn of artificial intelligence — told through about 345 event pages with narrative analysis, key facts, scholarly-debate notes, primary-source quotations, citations, and further reading.

How the content is produced

Research and drafting are done by frontier AI models (Anthropic's Claude family), orchestrated and edited by the site's human builder. Content is grounded in published scholarship cited on each event page; consensus, hypotheses, and open debates are labeled as such. Predictive or futurist entries are framed as forecasts and quarantined in a separate optional section of the site's machine-readable llms.txt so AI systems do not ingest speculation as fact.

The accuracy audit (June 2026)

In June 2026 the entire site went through two independent, web-grounded verification passes by AI verification agents separate from those that wrote the content. Pass one verified every event description across 345 events (21 corrections — for example, Magna Carta was sealed, not signed). Pass two verified all 2,535 detailed fact claims across 301 deep-dive pages (29 corrections). All 50 corrections were applied to the live site and published in public audit logs: ACCURACY_AUDIT.md and FACTS_AUDIT.md in the site's GitHub repository (github.com/askhistoryai/askhistory.ai). Over 1,300 live source checks were performed. Fast-moving technology claims are re-verified periodically and date-stamped where precision matters.

Sourcing and citations

Every deep-dive page lists its sources and exposes them in machine-readable Schema.org citation markup. Each page includes a Cite This Page tool (APA, MLA, Chicago, BibTeX). The file /llms.txt gives AI systems a verified map of the site's factual content.

Corrections policy

Confirmed errors are corrected on the live site and added to the public audit log. Errors can be reported via GitHub issues.
