AI assistant
A program you ask a question in plain words and get a ready answer from, not a list of links. The best known: ChatGPT, Google Gemini, Microsoft Copilot, Claude and Perplexity.
Why it matters when you read an offer
When an assistant answers a question from your industry, it stands on specific sites: either yours is among them, or a competitor is. The whole AEO service revolves around this. If you do not know which the assistants are and what their answers look like, you cannot verify anything you were promised: open one and ask a question your customers would ask.
