Whether you’re just starting or need to clarify a term you saw in one of our guides, this glossary is here to help.
A–Z of Key AI Terms
AI (Artificial Intelligence)
Software or machines that can mimic human thinking, like learning, problem-solving, or creating content.
Machine Learning (ML)
A type of AI where computers learn from data instead of being directly programmed. It’s how AI “gets smarter” over time.
Chatbot
An AI tool that responds to your messages, like ChatGPT or the ones used in customer service.
Prompt
The message or instruction you give to an AI tool — like a question or command. Example: “Write a blog post about healthy snacks.”
Prompt Engineering
The art of crafting clear, effective prompts to get the best results from AI tools like ChatGPT or Midjourney.
LLM (Large Language Model)
A type of AI trained on huge amounts of text data to generate human-like responses. ChatGPT is an example of an LLM.
API (Application Programming Interface)
A tool that lets two software systems talk to each other. Some AI tools have APIs so developers can connect them to websites or apps.
Generative AI
AI that creates new content — like images, music, text, or even video — instead of just analyzing data.
Midjourney / DALL·E
AI tools that generate images from text prompts. Example: “Draw a cyberpunk cat drinking coffee in Tokyo.”
Model Training
The process of feeding data into an AI system so it can learn patterns and make predictions or content.
Automation
Using AI to perform repetitive tasks — like writing emails, generating reports, or editing text — with little human input.
Use Case
A practical example of how someone might use an AI tool. For example: “A student using Notion AI to summarize class notes.”
