What AI is, and what it isn't
Artificial intelligence is software that learns patterns from data and uses them to produce outputs: predictions, recommendations, decisions or new content. The EU AI Act defines an AI system by one key ability: it infers from the input it receives how to generate those outputs, rather than only following rules a person wrote line by line.
Where you meet AI at work
- Chat assistants that draft, summarise and answer questions.
- Features inside everyday tools: email suggestions, meeting transcription, CRM lead scoring, HR screening, fraud alerts.
- Systems your company builds: pricing models, chatbots on the website, internal agents.
Many people use AI daily without noticing, because it arrives as a feature, not a separate product.
What AI is good at
- Drafting and rewriting text quickly.
- Summarising long documents.
- Finding patterns in large amounts of data.
- Answering routine questions at any hour.
What AI is not
- Not a source of truth. It can be fluent and wrong at the same time.
- Not neutral by default. It learns from data that may carry past bias.
- Not responsible. People and organisations stay accountable for what AI does on their behalf.
Note
A useful rule: treat AI like a fast, capable new colleague who has never worked here, sometimes makes things up, and needs their work checked.
