AI Agents Can't Search the Record Sites for You
MyHeritage and Ancestry both barred AI agents from their sites in 2026. What the terms actually say, and what AI is genuinely useful for at the search box.
Two of the biggest record sites changed their terms this year to bar AI agents. That closed a door a lot of family historians were being told to walk through.
The pitch had been everywhere: give the AI your ancestor's name, walk away, come back to a tree full of records. It was a good story and it was never a good plan.
Here is what the website terms actually say, why the agent was not the way to go, and what is worth doing with AI.
What an agentic browser actually is
The big change with LLMs in 2026 is that they can use tools now. That sentence is the concept behind everything you have heard about "agents."
A year ago an LLM could only talk. You typed, it answered. Now LLMs with tool use can act — they open a web page, click a button, fill in a form, and read what comes back, the way a person at a keyboard would. An agentic browser is that ability pointed at the web.
Applied to family history, the promise writes itself. You could type in a request and, like magic, AI would go out onto the internet and find every source you needed and present it to you.
What happens when an agent runs your search
But this is what actually happens when AI goes out and does searches for you.
The agent opens the site. It finds the search box, types a name, and reads a results page that was built for human eyes. Then it guesses which of forty entries matters, and clicks. Slowly it navigates, takes screenshots, and creates lists. You pay for all of this through usage in your AI account.
What it does not bring is your experience and wisdom: the sense of which spelling to try next, and which hit matches. Its mistakes are indistinguishable from correct choices until somebody checks. That is exactly the failure the Research Quality Check exists to catch.
And the worst part? It's 100x faster and more accurate for a human to do the searches themselves.
What MyHeritage and Ancestry changed in their terms
While some people ignored the poor performance and results and used agentic browsers, ultimately the genealogy websites decided to close access completely.
MyHeritage updated its terms on April 19, 2026 to bar AI agents, bots and automated systems from accessing or collecting data on the site. The terms go further: "You must not facilitate access to your MyHeritage account by any AI Tool or third-party automated interface." That covers pointing your own agent at your own paid account.
Ancestry's terms, effective May 12, 2026, do not use the word agent. They bar access "by any manual, automated, or programmatic method that exceeds the intended standard human use of the Services," and separately bar using site content to train or fine-tune AI. Different wording, same effect.
FamilySearch already banned this type of action back in 2023. They do not use the word AI or agent, but prohibit users from scraping and harvesting, which covers what agents do.
These are their published records and their rules, and companies and organizations are entitled to decide how their servers get used. What it means for you is simple: the AI-does-your-searching plan is off the table.
What AI can actually help you with
It is your coach.
Whichever AI tool you use, it knows more about how each site's search behaves than you have time to learn, and it can tell you before you type. Which wildcards this site honors. Why the exact-match toggle is quietly hiding half your hits. Which collections are machine-indexed, and what that does to an unusual surname. You ask, you learn, and then you search — with your own hands, on your own account, inside every site's rules.
Having AI as your search coach is the best position for AI. Nothing in these sites' terms says an AI cannot teach you about searching. What they bar is your software touching the site on your behalf, and AI as a coach never does. In fact, having AI there as your coach is something I expect every genealogy website to have in 2026 and 2027. Right now AI is positioned as an assistant, but with more knowledge of you and your goals, it could be so much more.
The coach makes you better at the thing you already do. The agent made you absent from it.
What to do with this
If you have an agentic browser pointed at a records account, unpoint it. Not because anyone is coming for you, but because the results were mediocre and the terms are clear, and there is no version of this where it was worth it.
Then ask AI to coach you through your searches. Ask it for techniques before you search, then go and run the search yourself, with the instincts and wisdom you have. Together that's a winning combo that letting AI agents loose never was.
