Tiller does offer a tool to help you automate your transaction categorization in Google Sheets, called AutoCat, available via the Tiller Money Feeds add-on for Google Sheets.
By default, Tiller does not automatically categorize your transactions like Mint and other personal finance apps. We believe that manually categorizing transactions helps you build awareness around your spending so that you can be more in tune with your money.
We also know that other tools try to categorize transactions for you and get it wrong. Tiller gives you ultimate control over your categories and categorization.
