These have a written guide instead — what the language is for, a first program, and how to run it on your own computer. Each guide says plainly that it does not run here.

A clear order for learning AI
If AI is your goal, follow these lessons in order and practice with the original examples.
Prefer a single overview first? Read the beginner AI roadmap, then use the plain-English neural network guide when you reach machine learning.
Understand what AI actually is
about 10 min of readingStart with AI Fundamentals. It explains how modern AI works in plain English — what a model is, how it learns, why it sometimes makes things up. Everything else on this site builds on these ideas.
Start AI Fundamentals →Learn to write prompts that work
about 8 min of readingPrompt Engineering for Real Work teaches the structure behind good prompts — why vague requests get vague answers, and how to iterate instead of settling for the first response. The Prompt Engineering hub collects the course, the guides, and the templates in one place.
Start Prompt Engineering →Apply it to your actual work
about 12 min of readingUsing AI in Everyday Work covers the practical side — emails, summaries, research, meeting notes — plus the judgment calls: what to verify, and what never to paste into an AI tool.
Start Using AI at Work →Understand AI agents before you use one
about 18 min of readingAgentic AI explains what changes when AI can act rather than only answer — how tools and the plan-act-check loop work, where agents fail, and the guardrails worth having. Take it once you are comfortable writing prompts.
Start Agentic AI →Practice with ready-made prompts
ongoingThe Prompt Library has original templates for writing, studying, job hunting, coding, and more — each with instructions and a real example. Copy one, fill in the blanks, and see the techniques from step 2 in action.
Browse the Prompt Library →Pick your tools
ongoingThe AI Tools Directory explains what each well-known tool actually does, who it suits, and its pricing model — independent write-ups, not marketing copy. Start with one general assistant and add tools only when a real need shows up, and read the head-to-head comparisons when you are weighing two specific tools.
Explore AI tools →Keep going
ongoingThe guides go deeper on single questions — how AI actually works, why it makes things up, how to fact-check it, and whether to trust an agent with real tasks. New lessons, tools, and articles are recorded with dates on the What's New page, so you can see what has been added since your last visit.

Two habits worth keeping from day one
- When you hit an unfamiliar term, look it up in the AI Glossary — every definition is one plain-English paragraph.
- Before trusting an AI answer that matters, read How to Fact-Check AI Output — it's the one article we'd make required reading.
