Connect Claude or ChatGPT to NatWest (2026)

Yes, NatWest works with Claude and ChatGPT through Era. You link your NatWest accounts over open banking, approve the connection in the NatWest app, and your assistant can then answer questions about your balances, your bills and your spending from your real transactions, next to every other bank you hold.

How do I connect NatWest to Claude?

Link NatWest in Era, then add Era to Claude. Era reads your NatWest accounts through open banking, so you approve access in the NatWest app or website 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 NatWest and continue to the NatWest 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 NatWest

Era brings in your NatWest current accounts, savings accounts, credit cards and the transactions behind them. NatWest's own app has budgeting tools, such as its spending insights, savings pots and Round Up Fund, and an assistant adds something the app cannot: the rest of your money, in the same conversation.

That matters because few people bank in only one place. Ask how much of your NatWest salary ends up in a Monzo or Starling pot, whether your savings are growing faster than your overspend on food, or what the cheapest month of the year has been for your bills.

Can ChatGPT read my NatWest account?

Yes. ChatGPT reads NatWest through the same Era connection as Claude, so the account you linked once is available in both. Add Era as a connector in ChatGPT, approve the consent screen, and ask about your direct debits, your card spending or the balance in each of your NatWest savings accounts.

Connect ChatGPT to your bank account walks through the steps.

Does NatWest work with Gemini?

Yes. Gemini can use Era as a connector and read the NatWest accounts you share, so you can ask it how this month's NatWest spending compares with last month's, or which bills come out in the days after payday. It reads only what you approve, and you can switch it off in Era.

Does NatWest work with Perplexity?

Yes. Perplexity can use Era as a connector, so it can pair its research with your NatWest figures. You might ask what savings rates are worth moving to, and have it read your current NatWest balances for the starting point. Perplexity sees only what you approve on Era's consent screen.

Does NatWest work with Grok?

Yes. Grok reads your NatWest 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 NatWest transactions using what really happened. Your NatWest login stays with NatWest, and you can switch Grok off whenever you like.

Does NatWest work with Meta's Muse?

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

Does NatWest work with Instinct?

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

Questions to ask about your NatWest money

• "How much did I spend on groceries across NatWest and my other cards last month?"
• "What goes out of my NatWest account by direct debit, and what is the total?"
• "How much have my savings grown since January?"
• "Which month this year did I spend most, and on what?"
• "How is my financial health, and what would move it most?"

If you share a household budget, an Era space lets each person see the balances they choose and mark a bill as paid. Your financial health figures come with the analysis behind them.

Does NatWest have its own AI assistant, API or MCP server?

NatWest offers open banking and a developer portal, which is the raw material a connector like Era's is built from. It has also begun rolling out an assistant of its own inside its Cora app, built on OpenAI models, and that assistant sees NatWest only. NatWest does not publish a ready-made connector for Claude or ChatGPT that a customer can add. Era gives you that connection without any code, and it covers the accounts you hold elsewhere too.

Is it safe to connect NatWest?

You approve access in the NatWest app and can withdraw it there at any time, and Era never sees your NatWest 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 NatWest asks you to confirm again.

If you would rather not connect, upload a NatWest 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? give the wider picture, and Barclays and Lloyds work the same way.
