What is ChatGPT?
Understand the tool people use every day before diving into the machinery underneath.
Start lessonA practical AI field guide
Learn what AI tools are actually doing.
Start with ChatGPT, then build a working mental model for tokens, context limits, prompting, hallucinations, and source-grounded answers.
Positioning
For people who want useful intuition, not hype.
Explain AI should feel like a well-edited technical guide for non-specialists. The site needs enough polish to feel trustworthy, but enough restraint to avoid looking like a generic AI landing page.
The design system should make the learning path, definitions, examples, and recap moments easier to follow. Decoration should earn its place by making structure visible.
Syllabus preview
Move from everyday tools to reliable judgment.
What are tokens?
See why small pieces of text affect cost, speed, memory, and answer quality.
Read guideWhy AI hallucinates
Learn why confident answers still need checking, and what reduces the risk.
Read guideWhat is RAG?
Learn how trusted source material can make answers more grounded.
Read guideLesson page model
Teach with examples, not visual tricks.
Long-form lessons should feel like calm technical reading. Use short sections, direct analogies, and simple diagrams that explain the idea without adding noise.
Think of context like desk space.
A model can only keep so much information in view at once. If the desk gets crowded, something has to move out before something new can fit.

Course material
A lesson page should feel like focused reading.
Course pages can use the same dark field-guide system while giving the lesson text a quieter, more readable column.
What is ChatGPT?
ChatGPT is an app that lets you talk to an AI model in plain language. The important part is not the chat box. It is the model behind it.
Think of it like a very fast writing partner
You give it words. It predicts useful next words based on patterns it learned from training data. That means it can explain, summarize, draft, compare, and reason through many everyday tasks.
Articles and blog
Room for timely ideas, not just course lessons.
The same design should support explainers, opinionated guides, tool breakdowns, classroom resources, and updates without making everything feel like a course module.
