Kubera · AI assistants · Claude

Kubera works with Claude.

Add Kubera as a custom connector and Claude can read your whole balance sheet: every bank, brokerage, crypto wallet, private fund, property, trust and entity. It can update it too, once you say yes: sync a stubborn bank, log a dividend from your inbox, revalue a fund from its statement.

Free for 14 days. No card. Nothing to cancel.

Then open a new chat and ask. Claude shows “Used Kubera” above any answer that came from your balance sheet.

Team and Enterprise plans: an Owner adds the connector under Organization settings, Connectors, then each person does steps 5 and 6 from their own Connectors page. Claude's own guide: Get started with custom connectors.

What to ask

Claude reads the balance sheet the way you would: every account, its history, and the fund schedules. So it can answer the questions a spreadsheet makes you work for. Two it answered from the demo account:

Example 1 · Idle cash

Find the cash that has gone to sleep

Claude read the item history, not just today's balances: three accounts untouched since 2021, a $5M account too new to count, and two accounts tagged as investments that your Cash on Hand leaves out.

How much cash do I have sitting idle in bank accounts since March 2026?
Used Kubera

You have $380,141 sitting idle across three bank accounts, flat since December 2021.

Bank of America$168,562since Dec 2021
Charles Schwab Savings$161,801since Dec 2021
Citibank$49,778since Dec 2021

Not included: Commbank ($5,000,000), added Sep 24, 2026, too new to count as idle.

Worth checking: Citibank and Commbank are tagged “investment”, so your Cash on Hand leaves them out.

Example 2 · Capital calls

Get the quarter's calls as a report

From the fund schedules in Kubera: one call due, no distributions expected, and which accounts can fund it. Claude also noticed a 2025 call with no payment recorded and a distribution that never arrived. The PDF is saved to Google Drive from the chat.

Can you make a PDF report for my upcoming capital calls and distributions for the remainder of 2026?

Claude can update Kubera too

Reading is half of it. Once connected, Claude can also keep the balance sheet current. Every change is proposed as a before-and-after and applied only after you say yes in the chat. Three ways people use it, in the order the video shows them.

1 · Web sync

Keep a stubborn bank in sync

For any bank or brokerage Kubera can't link, or a connection that keeps breaking. Claude opens the institution's site in its own browser, you sign in and grant permission, and Claude reads the balances and holdings. It can run on a schedule so the account stays current.

Needs the Claude desktop app and a paid Claude plan. How web sync works

Privacy, in short

Claude sees only what you have put in Kubera, and only while you are asking. It never sees your bank logins, because Kubera never stores them.

Questions

Do I need a paid Claude plan?

No. Custom connectors work on every Claude plan, including Free. Free accounts can add one custom connector, so Kubera can be it.

Does it work on my phone?

Yes. The connector belongs to your Claude account, so once it is added on the web it shows up in the Claude iPhone and Android apps and the desktop app.

Can Claude change things in Kubera?

Yes, when you ask. It can sync a bank account, log dividends and capital calls from your inbox, or update a fund from its statement. Every change is shown as a before-and-after first and applied only after you confirm in chat. It cannot move money, and for web sync you sign in to the bank yourself. Everything it changes shows in Kubera's history.

Does Kubera see my chats?

No. Claude sends Kubera a request for data, Kubera answers, and that is all Kubera sees.

Can my advisor's Claude see my Kubera?

Only if they connect with their own Kubera login and you have shared your portfolio with them. Each connector is tied to one Kubera account.

I use ChatGPT or Muse too. Same setup?

No, each AI connects differently. See the pages below, or the full list of supported AI assistants.

One number. Finally. Ask Claude about it.

Connect the first account and the balance sheet starts. Your daily history starts with it.
