If you’re new to AI, the terminology can feel overwhelming. Words like machine learning, LLMs, automation, workflows, and neural networks get thrown around everywhere — and most guides explain them in ways that make things even more confusing.
This glossary fixes that.
Below is a clean, simple list of the most helpful AI terms you’ll see as you explore tools, build workflows, and learn how to work smarter using AI.
No jargon. No technical fluff.
Just clear explanations anyone can understand.
🔍 Core AI Terms (Explained Simply)
AI (Artificial Intelligence)
Software that can learn, reason, or make decisions like a human.
Examples: ChatGPT, Midjourney, Notion AI.
You’ll use it for: writing, research, automation, content creation, business tasks.
Machine Learning (ML)
A method where computers learn patterns from data — instead of being explicitly programmed.
Example: an AI learns your writing style and can mimic it.
Neural Network
A system that works like a simplified digital brain.
It processes information in layers to understand patterns such as images, language, or speech.
Large Language Model (LLM)
A type of AI (like ChatGPT) trained on massive amounts of text.
It can generate writing, summarize content, answer questions, and create code.
Model Training
Feeding data to an AI so it learns patterns and improves accuracy.
Inference
When you ask an AI a question and it responds — that process is “inference.”
Prompt
The text you give an AI to tell it what you want.
Example:
“Explain quantum computing in simple terms.”
Good prompts = better results.
Prompt Engineering
The art of writing clear, structured prompts so AI outputs exactly what you need.
This is a skill you’ll use every day.
Token
A small piece of text AI reads or generates.
Words are broken into tokens.
Example:
“banana” → might be 1–2 tokens.
A paragraph → 50–80 tokens.
This matters because many tools bill per token.
📊 Data, Tools & Automation Terms
Dataset
A structured collection of information used to train or analyze with AI.
API (Application Programming Interface)
A way for software systems to communicate.
Example: using Zapier to connect ChatGPT to Google Sheets.
Automation
A process where AI or software completes tasks for you automatically.
Examples:
- auto-sending emails
- generating video captions
- organizing content
- scheduling posts
- summarizing messages
This is why AI saves so much time.
Workflow
A sequence of steps (manual or automated) to complete a task.
Example:
Upload → AI transcribes → AI summarizes → You publish → AI promotes.
RPA (Robotic Process Automation)
Software “bots” that perform repetitive digital tasks.
Think of it like automating virtual office work.
Integration
Connecting tools so they work together.
Example: Notion AI + Zapier + Google Drive.
🖼️ AI Creative Tools & Media Terms
Text-to-Image
You type a prompt → AI generates an image.
Example: Midjourney, DALL·E.
Text-to-Video
You write a scene → AI creates a full video.
Example: Sora, Runway.
This is the future of content creation.
Text-to-Speech (TTS)
AI converts written text into realistic voice audio.
Great for voiceovers, social media content, or tutorials.
Upscaling
Enhancing image or video quality using AI.
Avatar
A digital character generated or controlled by AI.
AI Editing
AI tools that automatically edit images, audio, or video.
Example:
Removing background noise, color correcting, or cutting silent moments.
🔐 AI Safety & Reliability Terms
Bias
When AI leans toward certain patterns because of its training data.
Hallucination
When AI generates something incorrect or made-up.
This is why fact-checking is essential.
Model Version
AI tools often release new versions.
Example: GPT-4 → GPT-5 → GPT-6.
Newer versions = more accurate and capable.
📌 Why These Terms Matter
Understanding these terms makes you:
- faster at learning new tools
- better at writing prompts
- more confident as AI evolves
- more productive in your workflow
- more prepared for future opportunities
The more familiar you are with this language, the more powerful AI becomes in your daily work.
