Vector Database
A database built to store embeddings and find the closest matches quickly. It is the part of an AI search system that decides which of your pages is relevant to a question.

AI Brand Mention
Your business being named in an AI answer, with or without a link. Worth tracking separately from traffic, because a mention can win the customer without ever producing a click.
AI Search
Searching by asking a question in ordinary language and getting a written reply, rather than typing keywords and choosing from links. It changes what a website has to do: be readable and quotable by a machine, not just findable.
Text-to-Speech
Turning written text into spoken audio. Modern voices are convincing enough to be used for real narration, which raises its own questions about disclosure.
LLM (Large Language Model)
The kind of AI behind ChatGPT, Claude and Gemini. It is trained on an enormous amount of text and predicts what should come next, which is enough to answer questions, summarise, translate and write.
Watermarking
Marking AI-generated content so it can be identified later, often invisibly. Part of the same effort as provenance, and equally early.
AI Policy Page
A public page stating how a business uses AI and what it does with customer data. Increasingly expected, and cheap to write honestly.
