ChatGPT
ChatGPT is OpenAI’s chat assistant. It writes, summarises, translates and analyses files from written or spoken instructions. It comes as a free version, individual subscriptions and business plans.
To answer customers with AI, start by having it prepare drafts from your own content, which an employee then approves. For a chatbot on your website, choose a tool that answers only from your information and hands over to a person. Since 2 August 2026, it must say clearly that it is an AI.

Tone: [courteous and concise], polite. Information: [FAQ, delivery times, return conditions]. Customer message: [paste the message without unnecessary data]

Only what it needs to answer, in line with the GDPR principle of data minimisation. Check where the provider hosts the conversations and sign a data processing agreement if it processes them for you. Mention this processing in your privacy policy.
