RPA (robotic process automation) imitates what a person does on screen by following fixed rules. AI automation understands the content —a PDF, an email, a WhatsApp message— even when its form changes, and decides the next step. They do not compete: the best solution often combines both.
What RPA is
A software "robot" that clicks, copies and pastes data between systems and follows a predefined flow. It works very well when information always arrives the same way and screens do not change. When a supplier changes its invoice layout or a page is updated, the robot stops and someone has to fix it.
What artificial intelligence adds
- Unstructured documents: reads invoices, contracts or forms in different layouts and extracts the data.
- Natural language: understands informal emails and messages, and replies.
- Judgement calls: classifies, prioritises and detects exceptions according to your rules.
- Tool use: an AI agent decides which system to query and which action to take.
Key differences
| Aspect | RPA | AI automation |
|---|---|---|
| Input | Fixed-format data | Variable documents, emails and messages |
| Logic | Step-by-step rules | A model that understands and decides, within rules and limits |
| Source changes | Breaks and needs reprogramming | Adapts if the content is still recognisable |
| Exceptions | Stops | Classifies them and hands them to a person |
| Integration | User interface (screens) | Preferably APIs and databases |
When to use each
- RPA: repetitive tasks on systems without an API, with data that always arrives the same way.
- AI: processes where someone has to read, understand or decide before acting.
- Both: AI interprets the document and RPA or an API records the result in a legacy system.
How to get started
- Pick a high-volume process, such as logging supplier invoices.
- Measure its current time and error rate.
- Run a pilot with real documents and human approval for uncertain cases.
- Expand in stages once results are measured.
Common mistakes
- Automating a process nobody has clearly defined.
- Using RPA to read documents whose layout changes.
- Letting AI execute payments or critical changes without approval.
- Not measuring: without a baseline you will not know what you saved.
