The short version
Tiller Money and BankBridge start from the same premise: your bank data should live somewhere you actually control, not inside a walled-garden dashboard some vendor built for you. From there they head in different directions.
Tiller pipes transactions into a Google Sheet or Excel workbook. You own the sheet, you shape the formulas, you look at the dashboard. It's a spreadsheet-first product for spreadsheet-first people, and it has a real following for that reason.
BankBridge pipes the same kind of data into your AI agent. You paste an API key into Claude or ChatGPT, and now the agent can answer money questions on demand. There's no sheet to open, no dashboard to build. You just ask.
Same idea, different destination. That's the whole comparison in one sentence.
What Tiller does well
Credit where it's due. Tiller has been shipping since 2016 and the product is polished:
- Daily push to Google Sheets or Excel. Every morning your transactions land in your sheet automatically. That reliability is the whole reason people pay.
- Templates that don't suck. Foundation, Yearly Budget, Debt Payoff, Net Worth. The community has extended them for years.
- You own the sheet. Cancel Tiller tomorrow, keep every row of history you ever pulled in. The data doesn't leave with them.
- Real categorization control. AutoCat rules, manual overrides, custom categories. You get to decide what "food" means.
- One flat price. $79/yr covers unlimited accounts. If you have six banks, Tiller is cheap.
None of this is what BankBridge does. BankBridge doesn't push to anything. It sits behind your agent and answers when asked.
What BankBridge does
BankBridge is a hosted MCP server at bankbridge.money. Sign up, link your banks, paste your API key into whichever agent you already use. After that, the agent can call 11 read-only tools: list accounts, query transactions, summarize spending by category or merchant, detect recurring charges, pull cashflow for any month, list investment holdings, and so on.
Every call live-fetches. Nothing is stored on our servers between requests. Auth is bearer token or OAuth 2.1 with dynamic client registration, so agents like ChatGPT can register themselves in one click.
The agent is the interface. There is no BankBridge dashboard to open. You open Claude, you ask "what did I spend at Costco last quarter," the agent calls the tools, you get an answer. That's the whole product.

Which one fits?
Two clear personas here. Most people will recognize themselves in one or the other within a sentence.
The dashboard person
You open a spreadsheet on Sunday morning. You have a favorite column layout. You look at the month's totals, tweak a category, notice that dining is up. You already run a household budget in Sheets and you'd like the raw transactions to arrive there without CSV imports.
Tiller is exactly for you. The daily push, the templates, the ownership of the sheet. It's the shortest path to what you already do.
The agent person
You already live in Claude or ChatGPT. You ask them for things all day. Opening a spreadsheet to look at your money feels like the past. You'd rather type "what were my top 5 merchants in June" and get an answer in the same window where you're already working.
BankBridge is exactly for you. No new app, no new tab, no formula to write. Paste the key once, ask questions forever.
They coexist fine
Some people run both. Tiller for the deliberate Sunday review, BankBridge for the Tuesday-afternoon "wait, did that Anthropic charge go through twice" question. The two don't step on each other because they answer different kinds of questions.
Two banks on BankBridge plus Tiller is around $17/mo combined. Fine if you'll use both surfaces regularly.
If you have to pick one
- Pick Tiller if the sheet is where you'll look. That's the whole product and it's good at it.
- Pick BankBridge if the agent is where you'll ask. No dashboard, no new app, no learning curve past pasting a key.
- Pick both if you already look at the sheet each week and want ad-hoc chat on top.
