Robotic Process Automation (RPA) executes predefined rules on structured data—clicking buttons, moving files, filling forms. AI agents use large language models to understand language, make decisions, and handle unstructured tasks. Gartner predicts that by 2026, 30% of RPA implementations will be augmented with AI agent capabilities.

RPA bots follow scripted steps: log in, click, copy, paste, submit. They're fast and reliable for structured, repetitive processes like invoice entry, data migration, and form filling. They break when the UI changes or the process varies.
AI agents use LLMs and integrations to handle language-heavy, decision-rich tasks: personalizing outreach, answering support questions, reviewing contracts, or researching leads. They adapt to variation and work with unstructured data (emails, documents, conversations).
Use RPA for high-volume, rule-based tasks on structured data (e.g. ERP data entry, report generation). Use AI agents for tasks that involve language, judgment, or variation (e.g. email triage, lead research, content generation). Many teams use both: RPA for the structured backbone, AI agents for the flexible front end.
For some tasks, yes—especially those involving language or unstructured data. For structured, high-volume data processing, RPA is often faster and more predictable. The trend is convergence: RPA vendors are adding AI, and agent platforms are adding structured automation.
Most RPA platforms (UiPath, Automation Anywhere) and AI agents offer no-code or low-code setup. You configure rules or prompts in a UI. Custom logic may require scripting in either case.
