What the AI does with
your Citi activity.
Connecting Citi isn't the finish line — it's the input. Here is what SuperBooks does with each transaction, and the one step that stays yours.
Every Citi transaction syncs into SuperBooks through Plaid — read-only. We can see the money move; we can never move it.
Upload a receipt, then attach it to the Citi transaction it belongs to. It stays linked from then on.
Each Citi expense is sorted into a category you control, and the expenses-by-category report adds them up for your accountant.
Profit and loss, burn rate and runway are computed from your Citi feed each time you open them, so they are never a month behind.
SuperBooks asks Plaid for up to 24 months of Citi history the moment you connect — how much comes back is Citi's call — so your first month starts with history already behind it.
Every currency,
kept as it happened.
Citi posts in USD. Invoice a client in EUR or pay a vendor in GBP: each account, transaction and invoice keeps the currency it happened in, and your invoice totals convert to USD at the day's published rate.
One read-only link to set up.
Up to two years of history.
SuperBooks asks Plaid for up to 24 months of Citi transactions and categorizes each one it is confident about.
We can't move your money.
That's by design.
Plaid handles authentication. We hold a read-only OAuth token and nothing else — your Citi credentials never touch our servers.

they connect Citi.
Straight answers, each one true of SuperBooks as it ships today rather than as it is planned.
Does Citi work with Plaid?
Yes. Plaid lists Citi as "Citibank Online", institution ID ins_5. In the snapshot of Plaid's institution list SuperBooks took on July 12, 2026, it is one of 9,761 active US institutions.
Can I connect Citi to QuickBooks or other accounting software?
SuperBooks has no QuickBooks connection: it is bookkeeping software itself, and it connects to Citi through Plaid. To take those transactions into another tool, export them as a CSV: one file of the transactions you select, with a column naming the bank account each one came from.
Do I need a Citi API or developer key?
No. SuperBooks reaches Citi through Plaid, read-only, and you connect with the Citi login you already use, so there are no developer credentials to request from the bank. Your own data is then readable over the SuperBooks REST API, its TypeScript and Python SDKs, and its MCP server — on every plan.
How do I link my Citi business and personal accounts?
Sign in to Citi through Plaid with the login that holds those accounts; SuperBooks then lists every account Plaid returns for it, and you choose which ones sync. All of them count as one bank connection on your plan. SuperBooks keeps one login per Plaid institution for each company — for Citi, Plaid's "Citibank Online" record — so connecting it again replaces that login instead of adding a second one. If your personal and business accounts sit under two separate logins there, only one of them can be connected at a time.
Does SuperBooks store my Citi login?
No. You sign in through Plaid — in Plaid's own window, or on Citi's own site if Citi uses OAuth — so your password goes to Plaid or Citi, never to SuperBooks. The only credential SuperBooks holds is a read-only token for transactions and balances — it can never move money — and disconnecting Citi revokes it.
How much Citi history comes across?
SuperBooks asks Plaid for up to 730 days — roughly two years — the first time you connect. How much of that actually arrives depends on what Citi makes available through Plaid.
Does SuperBooks categorize Citi transactions automatically?
Yes, when it is confident. SuperBooks applies a category above a 0.7 confidence score; below that it writes nothing rather than guessing, so the Citi transaction stays uncategorized in your list until you set it.
Can I export my Citi transactions?
Yes — your transactions export as a CSV on every plan and from every role, so you can hand Citi activity to an accountant or load it into another tool whenever you want.
What does connecting Citi cost?
Nothing to start: the free plan includes 1 bank connection and takes no credit card. Starter raises that to 3 connections and Pro to 10.
