Frequently asked questions

What AI terms should a small business owner understand first?

Artificial Intelligence, Prompt, Hallucination, Human Review and AI Governance. Together they cover what AI is, how you ask it for help, how it can go wrong, how to catch mistakes, and how to keep its use safe and appropriate in the business.

Do I need technical knowledge to use AI?

No. Most business-focused AI tools are designed to be used in plain language. A short internal policy, a small number of approved tools, and a human review step matter far more than technical knowledge.

What is the difference between AI and automation?

Automation follows fixed rules the same way every time. AI produces output based on patterns and context — useful for drafting, summarising and comparing, but it needs a person to check the result. Many practical workflows combine both.

What is an AI hallucination?

When an AI system produces information that sounds confident but is inaccurate or invented. Always review AI output before it is used in customer communications, quotations, contracts or policies.

Why does human review matter?

AI is a strong first draft, not a final answer. A short review step catches errors, tone problems, made-up facts and anything that shouldn't leave the business — and it keeps a real person accountable for the decision.

What is AI governance?

The set of rules, roles and checks a business uses to keep AI safe, accurate and appropriate. For a small business this can be a single page: approved tools, what must never be pasted in, when human review is required, and who to ask if in doubt.
