Plain language: A generative AI tool developed by OpenAI that generates text responses to user prompts. Currently the most widely recognised example of generative AI among the general public.

Technical: A conversational interface built on OpenAI's large language models (GPT-series), enabling users to interact with a generative AI system via natural language prompts across a wide range of tasks.

Misconception: 'ChatGPT' is frequently used as a synonym for all AI, in the same way 'Hoover' became a synonym for all vacuum cleaners. ChatGPT is one specific commercial tool within the much broader category of generative AI.

Real-world example: Students using ChatGPT to draft an essay outline; a professional using it to summarise a lengthy document; a parent using it to help draft a complaint letter.

Plain language: Microsoft's AI assistant, integrated into tools like Word, Teams and Outlook. Also functions as a useful conceptual metaphor: AI as a co-pilot that assists rather than a pilot that takes control.

Technical: A suite of generative AI capabilities developed by Microsoft, integrating large language model functionality into productivity software. The copilot metaphor, AI assisting rather than replacing human decision-making, has broader currency in AI communication beyond the branded product.

Misconception: The word 'copilot' can imply the AI is making decisions independently. The metaphor is chosen specifically to convey the opposite: the human remains in control; the AI assists.

Real-world example: Using Copilot in Microsoft Teams to produce a summary of a meeting you missed; using it in Word to suggest edits to a draft document while you retain final editorial control.
