You sit down to work on your family history. You open your family tree, pull up your notes, and open a genealogy website or two.
Then you realize you have no idea what to search for next.
You know who you’re researching. You may even know the mystery you want to solve. But turning that mystery into a step-by-step genealogy research plan is another matter.
This is one place where using AI for genealogy research can actually be helpful.
AI can help you take what you already know, develop a focused research question, brainstorm records to investigate, and put those searches into a logical order.
But there’s an important catch (there usually is).
AI can help create the plan. You still need to make sure the plan makes sense.
If you want a broader look at what AI does well, where it makes mistakes, and how I use it in family history research, read my guide to AI and genealogy. Here, we’re going to focus on one specific job: creating a genealogy research plan.
I’m Jessica from Heritage Discovered. I’ve been researching my own family for more than 20 years and working professionally as a genealogist for six. I specialize in Hawaii, New England, and French Canadian research.
If you’d rather have someone create and work through the research strategy for you, I also offer Done for You genealogy research services. If you’re not sure what you need, you can schedule a free 20-minute consultation.
What Should You Do Before Asking AI to Create a Genealogy Research Plan?
Before you open an AI tool, gather what you already know.
This matters because a useful genealogy research plan needs a starting point. If you give AI a vague question with little context, it has to fill in a lot of blanks. And sometimes it fills those blanks with assumptions you never made.
Start by gathering:
The person’s full name and known name variations
Approximate birth, marriage, and death dates
Places where the person lived
Known relatives and associates
Records you’ve already found
Records you’ve searched without finding anything
Conflicting information you haven’t resolved
Sources for the facts you’re providing
Don’t leave out unsuccessful searches. Knowing that you already searched a collection and found nothing can be just as useful when planning your next step.
A genealogy research log or genealogy records checklist can help here. My Genealogy Records Workbook gives you one place to track records you’ve found and identify records you may still need to search.
How Do You Turn a Family Mystery Into a Good Research Question?
Before using AI for genealogy research planning, decide exactly what you’re trying to learn.
“Find out more about Samuel Jones” isn’t specific enough.
“Who were the parents of Samuel Jones, who was born about 1811 in Massachusetts?” gives you something you can research.
Samuel is one of my own research problems. I know he was born around 1811 in Massachusetts, but I haven’t identified his parents. One strategy I’ve been working on is researching his neighbors and associates who were also born in Massachusetts.
That’s a much better starting point for a research plan than simply asking AI:
Who were Samuel Jones’s parents?
I don’t want AI to give me an answer. I want it to help me identify records and research strategies that might lead me to evidence.
If narrowing down your genealogy goals is where you tend to get stuck, my Family History Pathfinder walks you through identifying and prioritizing your research goals and breaking them into manageable steps.
What Information Should You Give AI About Your Ancestor?
Once you have your research question, give the AI enough context to work with.
Think of it like asking another genealogist for help. You wouldn’t walk up to someone and say, “Tell me how to find Samuel Jones,” then wander away (at least I hope not).
You’d explain what you already know.
For Samuel, I might provide:
Research question: Who were the parents of Samuel Jones, born about 1811 in Massachusetts?
Known information: A list of facts I’ve established about Samuel, along with the sources supporting them.
Previous research: Collections, databases, repositories, and individual records I’ve already searched.
Associates: People connected to Samuel who might help me trace him to an earlier place or family.
Conflicting evidence: Dates, places, names, or relationships that don’t agree.
The more clearly you separate what the records actually tell you from what you suspect, the easier it is to evaluate the plan AI gives you.
What Prompt Can You Use to Build an AI Genealogy Research Plan?
Now we can put AI to work.
Instead of asking, “What should I search next?”, give it instructions that force it to work from your research question and known evidence.
Try a prompt like this:
→ I am researching [ancestor] and trying to answer this research question: [question].
→ Here are the facts I have established and the sources supporting them: [facts and sources].
→ I have already searched: [records and collections].
→ I also have these unresolved conflicts or questions: [conflicts].
→ Create a prioritized genealogy research plan to help me answer my research question. For each step, suggest the record type to search, explain what information it might provide, and explain how that information could help answer my question.
→ Do not assume that a specific record or collection exists. If you suggest a repository or collection, tell me that I need to verify its holdings, location, coverage dates, and availability before searching it.
→ Separate facts I provided from assumptions or possibilities. Do not draw a genealogical conclusion for me.
Then look at what it gives you.
Maybe AI suggests probate records, deeds, church records, tax lists, court records, newspapers, or records involving Samuel’s associates.
Those are research suggestions, not evidence that those records exist or contain your ancestor.
That distinction matters.
How Do You Check an AI Research Plan Before Following It?
This is where using AI for genealogy research requires actual genealogy knowledge.
Go through every suggestion and ask:
Was this type of record created in this place during this period?
Which government, church, court, or other organization created it?
Does the record still exist?
Where is it held now?
What years does the collection cover?
Is it online, or do I need to contact a repository?
Have I already searched it?
Could this record realistically help answer my research question?
The National Archives gives similar guidance for its own AI search tool. It says AI-generated results aren’t guaranteed to be complete or accurate and that researchers are responsible for reviewing the underlying source documents to validate the information provided.
That’s a good rule to carry into any genealogy research involving AI.
Locality research becomes especially important here. Record keeping in Massachusetts won’t necessarily look like record keeping in Quebec or Hawaii.
My Locality Research Navigator can help you organize the repositories, record collections, maps, historical information, and other resources for the place you’re researching.
And don’t stop simply because the record isn’t online.
Many valuable family history records are still held by archives, libraries, historical societies, courthouses, and other repositories. Check their catalogs and finding aids, and contact the repository when you need help locating or requesting material.
If an archive holds a record you need and you can’t access it yourself, I can help with that research.
How Do You Update an AI Genealogy Research Plan When You Find Something New?
A genealogy research plan shouldn’t stay the same as your research moves forward.
Suppose you search one of the suggested records and discover a new location associated with your ancestor.
That changes things.
You may now have another jurisdiction to investigate, new record collections to find, or additional people to research.
Instead of starting over, give AI the new information:
→ I completed this step from my research plan: [step].
→ I searched [record or collection] and found [result]. Here is the source information: [source].
→ This new evidence tells me [what the record actually establishes].
→ Update my research plan based on this evidence. Keep my original research question in mind. Separate established facts from possible interpretations, and identify which previous steps should be changed, removed, or reprioritized.
Notice that you're telling AI what the evidence establishes rather than asking it to decide what the record proves.
That keeps you in control of the analysis.
When Should You Stop Asking AI and Analyze the Evidence Yourself?
There’s a point where AI brainstorming needs to give way to careful evidence analysis.
Slow down when:
Records contradict each other.
You’re trying to distinguish two people with the same name.
A relationship is implied but never directly stated.
You’re making assumptions based on proximity or association.
Historical boundary changes affect where records were created.
Several pieces of indirect evidence need to be considered together.
AI suggests a fact or source you can’t independently verify.
AI can give you ideas to investigate. Your conclusions need to come from the records and the evidence within them.
The National Archives makes the same distinction with AI-assisted searching. Its guidance tells researchers to review the source documents themselves rather than relying on information generated by the AI search tool.

Frequently Asked Questions About AI and Genealogy Research Planning
Should I upload information about living relatives to an AI tool?
Be cautious with information about living people.
Before uploading family trees, documents, DNA information, or other personal data, check the privacy policy and data controls for the specific AI tool you're using. Avoid sharing sensitive personal information unless you understand how that information will be stored and used.
For example, ChatGPT currently allows individual users to turn off “Improve the model for everyone” under Data Controls so new conversations aren’t used to improve OpenAI's models. Temporary Chats also aren't used to train OpenAI's models and are deleted from its systems after 30 days.
Other AI tools have their own policies, so check them individually.
Do I need to cite AI in my genealogy research notes?
If AI materially influenced your research process, documenting how you used it can help you understand your own work later.
At minimum, keep the AI-generated research plan with your genealogy research notes and record when you used it. More importantly, cite the actual historical records and sources you consult as a result of the plan. An AI suggestion that you search a probate file isn’t a substitute for documenting the probate file itself.
Should I save the prompts I use for genealogy research?
It can be useful, especially when you find a prompt that consistently helps you organize your genealogy research.
Saving the prompt alongside your research notes also gives you a record of what information you provided to the AI and what you asked it to do. If you return to the project months later (because somehow there’s always another branch), you won't have to reconstruct the entire process from memory.
A simple genealogy research log can include the date, research question, prompt used, AI tool, suggestions worth investigating, and the actual records you searched afterward.

Is Using AI for Genealogy Research Worth It?
For research planning, I think it can be.
Using AI for genealogy research works best when you give it a narrow job. Creating a list of possibilities, organizing research steps, and helping you see gaps can save you from sitting there wondering what to do next.
But the quality of the plan still depends on the information you provide and how carefully you check the suggestions.
Use AI to help you plan. Then go back to the records.
And remember that your next record may not be waiting in an online database. Check archive catalogs, library collections, historical societies, and other repositories too. Sometimes an email to an archivist can open a completely new research path.
