RPA automates repetitive tasks using software bots that mimic human actions in software systems: clicking buttons, copying data, filling forms. It is effective for rule-based, structured tasks.
An RPA bot breaks when the interface changes or when it encounters an exception it was not programmed for. AI-powered automation handles that variability through reasoning and language understanding. In practice, many enterprise environments run both: RPA for structured, predictable automation and AI for tasks requiring judgment, language understanding, or adaptability to variation.
