Why Does AI Use Water?
AI uses water to cool data centers and, indirectly, to generate their electricity. Learn how it works, why estimates vary and what per-prompt figures mean.
What Is an Algorithm?
An algorithm is a set of step-by-step instructions for solving a problem. See everyday examples, how social media algorithms work and what an AI algorithm is.
What Is Machine Learning?
Machine learning lets computers learn patterns from examples instead of following hand-written rules. See how it works step by step, with real examples.
How to Tell If Something Was Written by AI
No method can prove text was written by AI, and detectors can be wrong. Learn the clues worth checking, how accurate detectors are and what to do instead.
What Is a Neural Network?
A neural network is an AI model of connected layers that learns patterns from examples. See how it works, how it learns and how it differs from AI overall.

AI in Schools
How AI is used in schools today, what the research shows about learning, the real pros and cons, and practical questions parents and teachers can ask.
How Does AI Work?
AI works by learning patterns from data and using them to make predictions. Follow the process step by step, from training to the answers you see.
What Is a Deepfake?
A deepfake is AI-made or AI-altered video, audio or imagery of a real person. Learn to protect yourself, check suspicious media and know what the law says.

An AI agent uses tools to take actions and complete tasks. Learn what agents can do today, where they still fail and how they differ from chatbots.
How Long Has AI Been Around?
AI has been a field of research since 1956. See when AI started, who created it, the key moments on its timeline and when it finally became popular.
Which Jobs Will AI Replace, and Which It Will Not
No job is fully AI-proof, but AI changes work task by task. See which jobs face the most change, which are more resistant and what the evidence shows so far.
What Is RAG in AI?
RAG, or retrieval-augmented generation, lets AI look up relevant information before answering. See how it works, how it differs from fine-tuning and its limits.
What Is AI?
AI is technology that lets computers do tasks that normally need human intelligence. See a clear definition and real examples of AI you already use every day.
What Is AI Used For?
AI is used for prediction, recognition, language and creating content. See real artificial intelligence applications in work, health, finance, science and more.
How to Learn AI Skills
Learn AI skills in stages: understand the basics, practice with real tasks, write clear prompts and check results. No coding required to start.
What Is Generative AI?
Generative AI creates text, images, audio, video and code from prompts. Learn how it works, what it can make, how it differs from other AI and where it fails.
What Is a Large Language Model?
An LLM, or large language model, is AI trained on vast amounts of text to generate language. See how LLMs work, how they differ from chatbots and their limits.
What Is an AI Hallucination?
An AI hallucination is confident but false output, like a fake citation or invented fact. Learn why AI hallucinates, real examples and how to reduce the risk.
What Are AI Tools?
AI tools are software that uses AI to help with writing, research, images, audio, code, data and automation. See the main categories and how to choose one.
What Is a Token in AI?
A token is a piece of text an AI model reads and writes. See how tokens compare with words, why they set limits and costs, and how they differ from crypto.
How Do You Use AI?
Start using AI in a few steps: pick an assistant, describe your task clearly, refine the answer and check it. Includes example prompts and privacy tips.
AI vs Machine Learning vs Deep Learning
AI is the broad field, machine learning is AI that learns from data, and deep learning uses many-layered neural networks. See how the three compare.
What Is AGI? How Close Are We to Artificial General Intelligence?
AGI means AI with broad human-level ability across many tasks. There is no agreed definition or test, and no reliable way to say how close we are.
Where Does AI Get Its Training Data?
AI training data comes from web crawls, licensed material, human-written examples and synthetic data. Here is where each source comes from and why it matters.
Generative AI vs AI: What the Difference Actually Is
Generative AI is one part of AI, not a separate field. What divides it from prediction, detection and ranking, and when that boundary changes your decisions.
How to Write a Good AI Prompt
A good AI prompt gives the task, the context, the audience and the format. Four worked before and after examples, and why the better version works.
What Is AI Literacy?
AI literacy is knowing what AI can and cannot do, judging its output, and choosing when to use it. What the major frameworks say, and what it looks like.
Is It Safe to Put Your Information Into AI Tools?
Whether it is safe depends on the tool, the account and what you paste. What happens to your text, what not to share, and how to check any AI tool.
What Is AI Bias?
AI bias is a system producing worse outcomes for some groups. Documented cases in health care, hiring and face recognition, and the mechanisms behind them.
Does AI Remember Your Conversations?
The model does not remember you. The product remembers inside one conversation, up to the context window, and across chats only if memory is switched on.
What AI Still Cannot Do
What AI cannot do now, measured rather than asserted: unreliable self-knowledge, knowledge cutoffs, benchmark scores that do not transfer, and accountability.
Does AI Actually Make You More Productive?
Randomized trials disagree about whether AI makes people faster. What the studies measured, why the results conflict, and what it means for your own work.
Does AI Have Feelings?
AI produces emotional language because it was trained on ours. Whether anything is felt is unresolved, and the companies that build these systems say so.
How AI Voice Scams Work
Your ear is not a verification method. How AI voice scams work, what the research shows about detection, and the checks that actually settle who is calling.
How to Check Whether an AI Answer Is Right
Asking the AI again is not verification. A five-step method for checking an answer, what to check first, and how much effort each claim deserves.
How Does Facial Recognition Work?
A face becomes a template, a template becomes a score, and a score meets a threshold. Where the errors come from, and why accuracy depends on the picture.
What Is an Agentic Workflow?
Follow a single ordinary task through an agentic workflow: where the system chooses, where it calls a tool, where it stops, and where a person signs off.
How AI Screens Your Resume
Three different systems get called AI screening, and they fail differently. What the software really does, what it cannot infer, and what you can ask.
What Is a Reasoning Model?
Some models generate text before they answer. What that buys, where it helps, what it costs, and why the visible reasoning is not a record of the work.
What Is AI Inference?
Inference is the model answering you, once per request. What happens in those seconds, why the words appear one at a time, and why usage gets capped.
What Is an AI Model?
A model is not the app you open. It is the trained part inside it, with its own name, version and end date. Here is where one stops and the other starts.
Can AI Use Your Computer?
An AI can see a screenshot and name an action. Separate software carries it out, on your machine or on the provider's. What that needs, and where it breaks.
