How Tiller Works

Keep a clear view of your spending, etc

for Google Sheets and Microsoft Excel

Tiller automatically imports your spending, transactions, and balances into Google Sheets and Microsoft Excel and keeps everything organized by your custom categories and rules.

  • “Spreadsheets are the ultimate way to have complete control of your data. My workflows have moved to Claude. Agent-based productivity seems in the ‘spirit of Tiller.'”

    @thefakewaves, Tiller Community
  • “Tiller provides the structured financial data, while I use AI to help investigate transactions, compare information from bank exports, and organize receipts and warranties.”

    David O., Tiller Community
  • “The power of Tiller is the customizations within the Google Sheets, and with AI it’s a TOTAL step change to get exactly what you want.”

    Kevin B., Tiller Community

Automation

A personal finance system based in Google Sheets and Microsoft Excel

Unlike apps or AI bank connections, Tiller builds a financial source of truth you own in Google Sheets and Excel. Point AI at your spreadsheet instead of linking your banks. Ask questions about your money and explore your finances with any AI you choose. Your spreadsheet is yours, even without Tiller.
