What It Does
The Historical Accuracy Checker uses AI to analyze your historical fiction for period-specific accuracy, identifying anachronisms and inaccuracies that could break reader immersion.
It examines clothing and fashion, technology and inventions, language and expressions, social customs and etiquette, historical events and figures, geography, food and drink, transportation, weapons, medicine, currency, and architecture. The tool distinguishes between clear errors, possible issues, and acceptable stylistic choices.
How to Use It
Set Historical Context (Optional)
Specify the time period and location/setting for your text. If left blank, the AI will attempt to determine these from the content itself.

Best Practices
Provide Context When Possible
Specifying the time period and location helps the AI give more accurate feedback, especially for border eras where customs were changing.
Check Early in Your Process
Run historical checks on your first draft before deep revisions to catch fundamental research gaps early.
Use the Severity Levels
Focus on "error" severity issues first. "Suggestions" may be stylistic choices you intentionally made for readability.
Cross-Reference When Unsure
The AI provides high confidence ratings. For medium or low confidence issues, verify with additional historical sources.
