OpenTeller

About

Most budgeting applications connect to your bank via a third-party aggregator, and free services typically cover that cost by analyzing your spending habits. OpenTeller operates without any intermediary. You sign into your bank directly within the app, set it up just once, and then synchronize with a single tap. It works with any bank in any country, and your login details never leave your device. When using no account mode, your information stays encrypted within your personal iCloud. All categorization is processed locally using Apple Intelligence. You also have the option to integrate your own AI. An MCP endpoint allows tools like Claude and ChatGPT to access your data.
