Everyone is selling AI agents this year. The pitch is seductive: a digital employee that reads your inbox, books your meetings and runs your back office while you sleep. The reality is more modest — and for a small Swiss business, that is actually good news.

“Agent” has become the most overused word in AI. Every tool now claims to be one. Before you spend money or hand over client data, it is worth being precise about what an agent really does — and what it still cannot be trusted to do.

What an “agent” actually is

A chatbot answers. An agent acts. Under the hood, an agent takes a goal, decides the next step and carries it out using tools — search, spreadsheets, APIs, your own documents. It then looks at the result and decides the next step again. That loop — act, observe, decide, repeat — is the whole difference.

What reliably works today

If the task is narrow, repetitive and has clear rules, an agent can genuinely save you hours every week:

  • Inbox triage and drafting: read, sort and answer routine emails in your tone.
  • Document work: summarise, classify and extract from contracts, invoices and letters.
  • Retrieval over your files: answer questions grounded in your own documents, not the model’s memory.
  • Coding and data: small scripts, spreadsheets and report generation.
  • Workflows with a checkpoint: anything that drafts for you but waits for your approval before sending or paying.

What is still hype

Be careful with the following promises — they sound great and are not yet reliable at business level:

  • The fully autonomous employee that runs for days without oversight.
  • “Set it and forget it” on anything that involves judgement.
  • Sensitive data end-to-end without human review.
  • Long multi-step tasks where the model quietly drifts and confidently does the wrong thing.

Where they fail — and why it matters in Switzerland

  • Hallucination: an agent will invent a clause, a figure or a date rather than admit it does not know.
  • Cost and rate limits grow quickly when an agent loops many times.
  • The last mile: the first 90% is easy; the final polish and judgement still need you.
  • Data protection: under the Swiss Data Protection Act, client data must not flow into tools that train on it without care.

A simple test before you adopt one

Ask three questions:

  1. Is the task repetitive and rule-based, or does it need judgement?
  2. When it gets it wrong, can you catch the error cheaply?
  3. Can you keep sensitive data out — or use a compliant setup?

If you can answer all three comfortably, an agent will probably save you real time. If not, a template and a human in the loop is the better tool.

The honest bottom line

AI agents are real and useful — for narrow, supervised, well-defined work. They are not yet a fire-and-forget employee. The businesses that win are the ones that hand agents the boring, repetitive 20% and keep a human on every final decision.
