Which of the following is not an RPA tool?

Blackline is a software solution designed primarily for financial and accounting processes, including account reconciliation, financial close management, and financial reporting. It is not categorized as a Robotic Process Automation (RPA) tool, which is intended to automate repetitive tasks across various applications.

In contrast, Blue Prism, UiPath, and Automation Anywhere are all prominent RPA tools widely used for automating business processes. Each of these tools provides capabilities that allow organizations to automate workflows, integrate systems, and enhance productivity by minimizing manual interventions. Therefore, while Blue Prism, UiPath, and Automation Anywhere are built specifically to facilitate automation through bots, Blackline serves a different purpose within the financial software ecosystem.
