Connect Claude or ChatGPT to Nationwide (2026)

Nationwide works with Claude and ChatGPT through Era. You link your Nationwide accounts over open banking, approve the connection in the Nationwide app, and your assistant can then answer questions about your balances, bills and savings from your real transactions, alongside every other provider you use.

How do I connect Nationwide to Claude?

Link Nationwide in Era, then add Era to Claude. Era reads your Nationwide accounts through open banking, so you approve access in the Nationwide app and never share your online banking details. Claude then has one connection to everything you have linked, and setup takes a few minutes.

1. Sign up at era.app and choose Connect your bank.
2. Search for Nationwide and continue to the Nationwide app.
3. Approve the accounts you want to share, then return to Era.
4. In Claude, add Era from the connector directory, or use https://context.era.app/mcp as a custom connector.
5. Approve the consent screen and ask a question.

The guide to connecting Claude to your bank account has the full walkthrough.

What your assistant can see in Nationwide

Era brings in your Nationwide current accounts, savings accounts and credit cards, with the transactions behind them. As a building society, Nationwide tends to hold the long-term parts of people's money, such as a mortgage payment going out and an ISA building up, and an assistant can set those beside the rest of your life.

That makes it good for questions about the shape of a month. Ask how much of your FlexDirect balance is left after the mortgage and bills, how your ISA contributions compare with last year, or whether the interest on your savings beats what you pay on other debts.

Can ChatGPT read my Nationwide account?

Yes. ChatGPT reads Nationwide through the same Era connection as Claude, so linking once covers both. Add Era as a connector in ChatGPT, approve the consent screen, and ask about your standing orders, your card spending or the balance across your Nationwide savings.

Connect ChatGPT to your bank account walks through the steps.

Does Nationwide work with Gemini?

Yes. Gemini can use Era as a connector and read the Nationwide accounts you share. It suits questions such as how your Nationwide spending compares across the last three months, or which regular payments leave your account around the first of the month, and you can switch it off in Era.

Does Nationwide work with Perplexity?

Yes. Perplexity can use Era as a connector, so it can pair its research with your Nationwide figures. You might ask it what ISA rates look like, and have it read your Nationwide ISA balance and deposits to see whether you are using your allowance.

Does Nationwide work with Grok?

Yes. Grok reads your Nationwide accounts through Era once you approve the consent screen. Add Era as a connector in Grok, accept the consent screen, and it can answer direct questions about your Nationwide transactions from what really happened, with no banking details shared.

Does Nationwide work with Meta's Muse?

Yes. Meta's Muse can connect to Era and read the Nationwide accounts you have shared. You approve it on Era's consent screen, you can switch it off whenever you like, and your Nationwide connection stays in place. Muse sees only what you allow, and never your Nationwide password.

Does Nationwide work with Instinct?

Yes. Instinct connects to Era and reads your Nationwide accounts along with the rest, so a question about your regular payments or your savings gets an answer from your real transactions. You approve access in the Nationwide app, so no assistant ever handles your login.

Questions to ask about your Nationwide money

• "What is left in my FlexDirect account after bills and the mortgage?"
• "How much have I paid into my ISA this year?"
• "Which payments leave my Nationwide account by standing order?"
• "How does my savings growth compare with last year?"
• "What happens to my financial health if I overpay the mortgage a little each month?"

Does Nationwide have its own API or MCP server?

Nationwide supports open banking and does not publish a ready-made connector for Claude or ChatGPT that a customer can add. Era supplies the connection: you link Nationwide once, and every assistant you use reads the same accounts, together with your other banks, with no code and no keys.

Is it safe to connect Nationwide?

You approve access in the Nationwide app and can withdraw it there at any time, and Era never sees your Nationwide login. Era encrypts your data with AES-256 at rest and TLS 1.3 in transit, never sells it, and no model provider trains on it. Era shows a Reconnect button when Nationwide asks you to confirm again.

If you would rather not connect, upload a Nationwide statement and Era fills a manual account from it. Does Claude support open banking in the UK? and can ChatGPT connect to my UK bank account? cover the wider picture, and Santander UK and Halifax work the same way.
