RPA vs agentic AI: scripted robots or agents that choose their steps

UiPath's agent documentation draws the line directly. RPA robots are 'deterministic systems' that 'follow structured logic and fixed rules', while agents 'use a probabilistic approach to make decisions based on patterns and real-time data' and are designed to operate in 'dynamic, non-deterministic environments'.

IBM defines agentic AI as a system that 'can accomplish a specific goal with limited supervision'. The word that matters here is goal. A robot receives a sequence. An agent receives an outcome and works out the sequence, which is why the two fail, and grow, in different ways.

Every RPA programme has an exception queue: the cases a robot could not complete, waiting for a person. UiPath's documentation says agents are suited to 'unstructured, exception-heavy workflows where conditions and outcomes vary', which describes the contents of that queue closely.

An agent can open the stuck case, look up the missing information through a tool, decide whether it can finish the case and, if not, escalate it with a summary. UiPath describes agents that escalate to humans when needed. The person still decides the hard cases, but arrives with the context already gathered.

A supplier emails asking to change the bank account on file. An RPA robot can update the field in the ERP once someone has keyed in the request, but it cannot judge whether the email is genuine. A rule that checks the sender's domain catches some fraud and misses the rest.

An agentic flow reads the email, compares the sender with the supplier record, checks recent correspondence for the same request and flags signs of impersonation. It prepares the change and stops. A named person in accounts payable confirms the request by phone on the number already held, approves it, and only then does the update run: by API if the ERP has one, or through the existing robot if it does not.

UiPath describes agentic automation as coordinating agents, robots and people together. That matches a practical split in which the agent decides, the robot executes on screens with no API, and people own the consequential decisions.

• Leave stable, high-volume screen work with the robot. OpenAI's agent guide notes that where its agent criteria are not clearly met, a deterministic solution may suffice.
• Give the agent the steps that need reading, comparing and deciding, starting with the cases that now sit in the exception queue.
• Put a person in front of every action that moves money, changes master data or contacts a customer, and record who approved it.
• Measure the agent against the old exception queue: how many cases it closes, how many it escalates, and how many a person later reverses.

With RPA, the control question is whether the script is correct. With agentic AI, the control question is what the agent is allowed to do. An agent with access to the ERP and to email could take actions nobody scripted, so its tools must be limited, its consequential actions gated and every decision recorded with the input it was based on.

Studio builds the agent side of this split. An agent in Studio can read the case, call tools through integrations and models through Connect, and hand off to an approval step that pauses the run for a named person. Nexus adds policy, approval and audit around agent runtimes.

Swfte does not build or run RPA robots, and Studio cannot drive a desktop screen. If your ERP is reachable only through its interface, the robot stays. SAML SSO and SCIM are in development and not generally available, so check that against your identity requirements first.
