How to Use AI for Family History: Family Tree Help and Old Photos
Use ChatGPT or Gemini to organize what you know about your family tree, plan questions for relatives, read old handwriting and restore old photos, without letting AI make up ancestors.
Quick answer: AI is a good helper for family history, but not a good source. Use a free app like ChatGPT or Gemini to sort what you already know into a simple family tree, write questions to ask your relatives, help you read old handwriting, and gently restore old photos. Then check every name and date against real records, such as the free Full-Text Search on FamilySearch.org. Never copy an ancestor into your tree just because a chatbot said so. Chatbots sometimes invent people and records that sound real.
Family history is a lovely project for a slow afternoon. You likely already hold the best material: names in a Bible, a shoebox of photos, stories you heard at the kitchen table. AI can help you get it organized and keep it moving, as long as the facts come from people and papers, not from the chatbot.
What AI is good at (and what it isn't)
| Good job for AI | Not a job for AI |
|---|---|
| Turning your notes into a tidy family tree outline | Telling you who your great-grandparents were |
| Writing questions to ask an aunt or cousin | Finding a birth or marriage record by itself |
| Helping read hard-to-read handwriting | Being the final word on a name or date |
| Explaining old words, jobs and places | Guessing missing branches to fill gaps |
| Restoring scratches and fading in a photo | Changing faces or making a photo "better" than it was |
The simple rule: AI helps you work. Records and relatives give you facts.
Step 1: Write down what you already know
Start with yourself and work backward. Jot down every name, rough date and place you know for your parents, grandparents and great-grandparents. Guesses are fine. Mark them with a question mark. Then let AI tidy it up:
Here are notes about my family. Please turn them into a simple family tree outline, one generation at a time, starting with me. Use only what I wrote. Do not add any names, dates or places. Mark anything with a question mark as "not sure." At the end, list the gaps I should try to fill. [paste or type your notes]
That last line matters. The list of gaps becomes your to-do list.
Keep the real tree somewhere safe and lasting: on paper, in a document, or in a free family tree site like FamilySearch (free, run by a nonprofit) or a free Ancestry or MyHeritage account. The chat is a scratch pad, not your archive.
Step 2: Ask AI to help you interview relatives
The oldest people in your family are your best record. A few good questions can bring back names no website has. Ask:
I'm going to call my [aunt / older cousin / mother] about our family history. Write 12 gentle, open questions I can ask, starting easy (where she grew up, her parents' names) and moving to stories (holidays, jobs, moves, who lived with whom). Keep each question short. Add a note on how to ask kindly about people who died young or family members who were not talked about.
Record the call if they agree (most phones can record voice memos), or take notes. Afterward, paste your notes back and ask the AI to pull out every name, date and place into a list you can check.

Step 3: Check the facts in real records
This is where real discoveries happen, and it's free.
- FamilySearch Full-Text Search. Create a free account at FamilySearch.org, then choose Search → Full-Text. It uses AI handwriting recognition to search old documents that were never typed up, like deeds, wills and court records, by name and place. It is in English, Spanish and Portuguese so far, with more languages being added in 2026. Open the original image to confirm what it says, because computer transcripts make mistakes.
- FamilySearch AI Research Assistant. Once you add people to your tree on FamilySearch, a list of suggested records appears at the top of your home page. Tap Review and compare each one before you attach it. A matching name is not always the same person.
- Your own papers. Birth and death certificates, obituaries, funeral cards, military discharge papers, and the family Bible are often the most reliable records you'll find.
Tip from experienced genealogists: search with just the name first, then narrow by place. Spelling changed a lot over the years, so try a few versions.
Step 4: Get help reading old handwriting
Old letters and records can be hard to read. Take a clear photo of the page in good light, upload it to ChatGPT or Gemini (tap the + button), and ask:
This is a photo of an old handwritten [letter / record] from about [year] in [place]. Please type out what it says, line by line. Put [?] next to any word you are not sure about, and do not guess at names. Then explain in plain words what the document is.
Read the result next to the original. AI can misread names, so treat its typing as a first draft, not the answer. If a word is key (a surname, a town), ask a relative, a library, or a FamilySearch volunteer to take a look too.
AI is also handy for old words. Try: "My great-grandfather's job is listed as 'cordwainer' in 1880. What did that mean?" (It's a shoemaker.)
Step 5: Restore old photos, carefully
Free AI apps can now remove scratches, creases and fading from old photos, and even add color.
- Make a good copy first. Lay the photo flat by a window in daylight, with no flash, and take a picture straight down. A scanner is even better if you have one. Keep the original print and the plain copy.
- Open Gemini or ChatGPT. In Gemini, tap + to add your photo (or choose Create images from the tools menu). In ChatGPT, tap + and choose your photo. You need to be signed in, and Gemini's photo editing is for adults 18 and over.
- Paste a careful prompt:
Please restore this old photo. Remove scratches, dust, creases and fading. Keep every person's face, expression, age, hair and clothing exactly the same. Do not smooth skin, make anyone look younger, or add anything that was not in the original.
- Compare side by side. Zoom in on faces. If someone looks a little different, reply: "Keep her face exactly as in the original." Try again, or simply use the plain copy.
- Label it. Save the restored version with a name like "Grandma Ruth 1946 - AI restored", so future family members know it was edited.
Free accounts can only edit a few images a day. Family history sites also have photo tools: MyHeritage lets anyone enhance and colorize several photos for free (with a small logo), and charges a subscription after that.
AI fills in damaged spots with what it thinks was there. That's fine for a frame on the wall, but it can change small details, and sometimes faces. Always keep the original, and don't use an AI-restored photo as proof of who someone was.
Privacy: be kind to living relatives
- Share less about the living. It's usual to use full names and dates for people who have died. For living relatives, first names are enough when chatting with AI.
- Leave out ID numbers. No Social Security numbers, account numbers or full birth dates of living people. See what never to paste into AI.
- Think twice before posting. Public family trees, and old photos posted online, can be copied. Many sites let you keep a tree private.
- DNA tests are a separate choice. They can reveal surprises about relatives. Talk it over with family first, and read the company's privacy settings.
- Delete chats when you're done if you'd rather they weren't saved. Here's how to clear AI chat history.
A family history afternoon with the grandkids
This is a wonderful thing to do together. Grandchildren are often quick with the phone, and you have the stories. Pick one old photo, restore it together, then ask the AI: "Write five questions a 10-year-old could ask Grandma about this photo." Record the answers. That one afternoon can become a page in your family life story. For bedtime stories, riddles and homework help, see AI for grandparents: fun, safe ways to use AI with your grandkids.
FAQ
Can ChatGPT build my family tree? It can organize the names and dates you give it into a neat family tree outline, and suggest what to look for next. It can't look up your ancestors for you, and if you ask it to fill in gaps, it may invent people. Check every new name in real records.
Is there a free AI tool for genealogy? Yes. FamilySearch is free and has Full-Text Search, which uses AI to read old handwritten records, plus an AI Research Assistant that suggests records for people in your tree. ChatGPT, Gemini and Copilot are free for organizing notes, writing interview questions and reading old handwriting.
Can AI read old handwriting? Often, yes. Upload a clear photo of the page to ChatGPT or Gemini and ask it to type it out and mark any word it isn't sure about. It can misread names and old spellings, so compare its typing with the original.
How do I restore an old photo with AI for free? Take a clear photo of the print in daylight, upload it to the Gemini or ChatGPT app, and ask it to remove scratches and fading while keeping every face exactly the same. Compare the result with the original, keep both, and label the restored one as AI-edited.
Can AI make up ancestors? Yes. Chatbots sometimes invent records, dates and relatives that sound believable. Genealogists have reported ChatGPT describing a marriage record that didn't exist. Use AI to organize and explain, and get the facts from documents and relatives.
Is it safe to put family names into ChatGPT? Names and dates of relatives who have died are generally fine. For living family, use first names only, and never share ID numbers, account details or full birth dates. You can delete the chat afterward.
