# Which AI Assistants Can Connect to Your Family Tree? Gemini, Perplexity, Le Chat and Copilot

Every big AI assistant can read a document you paste in. Far fewer let you connect your own family archive, and the rules differ by country, plan and account type. Here is which assistants accept a custom connector as of October 2026, what each one requires, and where it is still a no.

Claims about Gemini, Perplexity, Le Chat, Microsoft Copilot, ChatGPT, Claude and KleioBase last verified 2026-10-30.


You already use an AI assistant for family history: to read a German church entry, to suggest where a Kentucky death might be registered, to turn your notes into a story. For many people, that is the one that came with their phone or browser. Then you read that Claude and ChatGPT can now be connected to a family archive, so they answer from your records instead of from memory, and you wonder whether yours can too.

The answer depends on the assistant, and for some of them on where you live and what kind of account you sign in with.

**The short answer.** As of 30 October 2026, Claude and ChatGPT both let you add a custom connector, the kind that links an assistant to your own research through the Model Context Protocol (MCP). Google's Gemini app does too, but Google's help page limits it to people aged 18 or over in the US, signed in with a personal Google Account, in English. Perplexity documents custom remote connectors, but its help page does not say which individual plans include them. Mistral announced custom MCP connectors in Le Chat in September 2025 and said they were on the free plan. For the consumer Microsoft Copilot app, we found no way to add your own connector; Microsoft's MCP options are for Copilot Studio and work accounts. Any assistant on this list can still read a document you paste in.

## What a connector changes

Without a connection, every assistant works from what you paste. That is fine for reading a document and risky for anything else, because an assistant asked about a specific ancestor tends to produce something shaped like an answer. William Walters and Esther Wilder showed how far that can go in *Scientific Reports* in 2023: of 636 citations ChatGPT produced for literature reviews on 42 topics, 55 per cent from GPT-3.5 and 18 per cent from GPT-4 were fabricated. Nobody has measured the same thing for genealogical records, as far as we could find in October 2026, and in our view there is no reason to think registers are safer than journals.

A connector gives the assistant a way to look things up in a system you trust while it works, instead of recalling. MCP is the open standard most assistants now use for this. Connected to a family archive, an assistant can search your people and records, read a timeline, and open the record behind a fact, so you can ask it where an answer came from and check.

## The assistants, one by one

Everything below comes from each company's own help pages, read on 30 October 2026. The menus move often, so if a step does not match what you see, the company's help page is the place to check.

| Assistant | Custom connector? | Who can add one | Where |
| --- | --- | --- | --- |
| Claude | Yes | Free, Pro, Max, Team and Enterprise; Free is limited to one custom connector | Customize > Connectors |
| ChatGPT | Yes | Depends on your plan; in a work workspace, an admin controls it | Plugins > Add > Add custom MCP server, on the web |
| Gemini | Yes, with restrictions | 18 or over, in the US, personal Google Account, English | Settings > Connected Apps > Custom apps, on gemini.google.com |
| Perplexity | Yes | Not stated for individual plans | Plugins > Add custom > Add MCP connector |
| Le Chat | Yes, per Mistral's 2025 announcement | Free plan included, per that announcement | Not checked |
| Microsoft Copilot | No route found for personal accounts | Copilot Studio and Microsoft 365, with work accounts | Not available in the consumer app |

**Claude and ChatGPT have their own guides.** They are the two most mature, and the details matter enough for separate walkthroughs: [how to use Claude for genealogy](/blog/how-to-use-claude-for-genealogy) and [how to use ChatGPT for genealogy](/blog/how-to-use-chatgpt-for-genealogy). Claude allows one custom connector on its free plan. For ChatGPT, whether the option appears depends on your plan and workspace settings.

**Gemini works if you are its intended user.** Google's help article on custom apps for Gemini says you must be 18 or over and in the US, signed in with a personal Google Account rather than a work or school one, with Keep Activity turned on, and that custom apps are only available in English. You add the connector on gemini.google.com under Settings > Connected Apps (or Personal Intelligence > Connected Apps), then Custom apps > Add a custom app, and paste the server's address. Once added, it also works in the Gemini mobile app. Google says Gemini currently asks for manual confirmation before any write action, and warns that it may share information from your chat with the connected app.

**Perplexity documents it, and leaves the plan question open.** Perplexity's help article on custom remote connectors, last modified on 28 October 2026, gives the steps for your own account: open Plugins in the sidebar (or Customize > Connectors on older layouts), choose Add custom > Add MCP connector, select Remote, enter a name and the server address, choose OAuth under Advanced, tick the acknowledgement and select Add. The article sits under Perplexity's enterprise features and does not say which personal plans include it. In an organisation, members can only add their own connectors if an administrator has switched on Allow members to add custom connectors, which is off by default.

**Le Chat announced it, and we could not check the details.** Mistral's announcement of 2 September 2025 says Le Chat users can add their own MCP connectors and connect to any remote MCP server, and that everything announced was available on the free plan. The help article that describes the menu returned a missing page when we looked for it, so we have not given steps.

**Copilot is the gap.** We searched for Microsoft documentation in October 2026 and found no way for someone with a personal Microsoft account to add a custom connector to the Copilot app. Microsoft's MCP features sit in Copilot Studio, which a maker uses to build an agent, and in Microsoft 365 Copilot, where an administrator sets up connectors for an organisation. If you use Copilot at home, paste the document in and treat the answer as a reading of that page and nothing more.

**Developer tools are another route.** Coding assistants and desktop tools that support remote MCP servers, such as Claude Code, can connect to the same address. If you already use one, its own documentation explains where to add a remote server.

## Connecting your family archive

We make KleioBase, so read this section and the next as disclosure. KleioBase is an AI research companion that turns scattered historical records into one connected family archive, and its MCP server works with the assistants above that accept a custom connector.

The address is the same for every assistant: `https://kleiobase.com/api/mcp`. Add it as a custom connector, choose OAuth where the assistant asks how to sign in, and the assistant opens a KleioBase page. Sign in, choose **Read only** or **Read and write**, and select **Allow access**. The [Connecting AI assistants guide](/docs/ai-assistants) has the current steps.

**What we have tested, and what we have not.** We have connected KleioBase from Claude and ChatGPT. KleioBase supports the sign-in method the Gemini and Perplexity pages describe, OAuth with automatic client registration, but we have not run a connection from Gemini, Perplexity or Le Chat ourselves. Treat those as expected to work rather than confirmed, and if one fails, tell us.

**Start with Read only, whichever assistant you use.** A Read only connection can look anything up and change nothing. Of KleioBase's 88 tools, 35 only read, and every tool that deletes, overwrites or merges is marked as destructive even when it can be undone, so an assistant that asks before risky actions knows which ones to ask about. Settings > Developer in KleioBase lists every connected assistant and when it was last used, and **Revoke** cuts it off at once.

**What the assistant reads leaves our hands.** When an assistant reads your research, the company behind it handles that information under its own terms, not ours. Each one has its own settings for whether chats are kept or used for training. Check them before you connect a tree that includes living relatives, for the reasons in our guide to [what not to publish about living relatives](/blog/genealogy-privacy-ethics-publishing-family-data).

## What KleioBase does with an AI assistant, and what it does not

Once connected, the assistant works on the same archive you see in KleioBase: people linked across every record that names them, family trees, timelines, the scans themselves, suspected duplicates and the list of records each person should have but does not, based on where and when they lived. Our post on [a family tree that shows what is missing](/blog/family-tree-that-shows-what-is-missing) describes how the family tree itself marks missing parents and empty fields. Connecting is included on every plan, including the free Explorer plan, and your plan's limits apply as they do in the app.

There are three honest limits.

**The assistant still draws its own conclusions.** It reads the same records you see, but what it infers from them is its own and can be wrong. Ask which record a claim came from before you accept a merge or a correction.

**Photos only.** Record uploads must be JPG or PNG, one image per record. For files on your computer, ask the assistant for an upload link, a KleioBase page valid for 15 minutes where you drop the images in.

**It does not search other sites.** A connection gives the assistant your archive. It does not reach FamilySearch, Ancestry or an archive's catalogue, so finding a record you do not have yet is still a search.

## Where to start with the assistant you already use

Look up your assistant in the table. If it accepts a custom connector, add the archive with Read only and ask one question you could not answer from a pasted profile: who in your tree has no death date, and what is the last record you hold for each of them.

If it does not, use it for what every assistant does well. Paste in one document, say what kind of record it is and where it came from, and ask it to mark every word it cannot read.

The parish priests, registrars and enumerators who made these records did not write for machines, and no connector changes what they wrote. What a connector adds is the ability to ask the assistant where an answer came from and get back a record you can open.
