History Detective: Primary Sources and AI

A primary source is something made at the time of the event. A letter a soldier wrote from World War II, a speech Abraham Lincoln actually gave, a photograph from 1925, a diary from a colonial farmer. These are the real stuff of history.

The problem: old writing is hard to read. The words are different. The spelling is weird. The handwriting can be messy. This is where AI helps.

How AI can help

• Translate old-fashioned English into today's words
• Explain words that have changed meaning over time
• Give the background of what was happening that year
• Suggest questions to ask about the source

The detective mindset

AI can tell you what a source says, but you still have to ask the detective questions: Who wrote this? Who were they writing to? What did they want? What were they hiding? AI can help you brainstorm these questions, but you have to decide the answers.

1. 1Read the source yourself first
2. 2Look up anything you do not understand with AI
3. 3Ask AI: 'What questions should I ask about this source?'
4. 4Answer those questions in your own words
5. 5Find a second source to check

Cool thing to try

Find an old diary entry online (search 'historical diary primary source'). Paste it into ChatGPT or Claude. Ask: 'What was going on in this person's world? What do I need to know to understand them?' You just did real history.

“History is not a list of dates. It is a conversation with people who are no longer here.”

The big idea: history lives in old documents, and AI is a great translator. But the thinking, the connecting dots, the deciding what it all means - that is your job as the detective.
