Breakdown is a Chrome extension developed by John Dimm that allows users to analyze and visualize their financial transactions from Mint and Personal Capital. By loading the data into Lovefield, a browser-based local database, Breakdown can provide insights into spending habits and answer questions like "Where did all my money go?" or "How did I spend more on vacation this year than usual?" The interface is versatile and can work with various types of multidimensional data.

To get started, users need to follow a simple three-step process. First, install the Chrome extension. Then, export the transaction data from Mint or Personal Capital in CSV format. Finally, import the CSV file into Breakdown using the extension. The entire process is straightforward and requires only a few button clicks.

One of the key advantages of Breakdown is that all the data stays on the user's machine. There are no user accounts or logins, and no interaction with any server. Users have full control over their data and can view the Lovefield database in the Chrome Developer Tools.

Overall, Breakdown is a useful tool for individuals who want to gain insights into their financial transactions from Mint and Personal Capital. It provides a simple and secure way to analyze and visualize personal financial data.
