How the web and AI work, in plain language.
SEO, web analytics, APIs, how AI works: we explain the terms you meet in web work so you don't need to be an expert to follow them.
How AI works
Large language models, embeddings, RAG, AI agents: how AI produces its answers.
What is a large language model (LLM)?
A large language model (LLM) is an AI model that learns how words fit together from huge amounts of text and writes by predicting what comes next.
What are embeddings?
Embeddings represent the meaning of text or images as lists of numbers (vectors), so software can find related content even when the wording differs.
What is retrieval-augmented generation (RAG)?
Retrieval-augmented generation (RAG) has AI search relevant documents before it answers and base its reply on what it finds, so answers can cite sources.
What is an AI agent?
An AI agent is a system where a large language model plans steps, uses tools, and checks results to reach a goal. The key is deciding where people step in.
What is speech recognition?
Speech recognition is technology that lets a computer turn spoken words into text. Knowing how it works helps you get more out of dictation and transcripts.
What is text-to-speech?
Text-to-speech is technology that lets a computer read written text aloud. Knowing how it works helps you use read-aloud and voice messages with confidence.
What is a prompt?
A prompt is the text you give an AI: your request plus any background, sources and examples. Clear goals and conditions get you closer to the answer you need.
Websites and search
SEO, web analytics, cookies: the basics of growing a website.
What is SEO?
SEO (search engine optimization) helps search engines understand your pages and helps searchers pick them. Rankings can't be bought; useful content comes first.
What is web analytics?
Web analytics is measuring where your site's visitors come from, which pages they view, and whether they inquire or sign up, so you know what to improve.
What are cookies?
Cookies are small pieces of data a website stores in your browser. They keep you signed in and remember carts, but can also track people across sites.
What is a conversion?
A conversion is an action you decide to count as a result on your website, such as sending an inquiry or booking a trial. Choosing it shows you what to fix.
Connecting tools
APIs and webhooks: how tools exchange data with each other.
What is an API?
An API is a defined way for software to exchange data and actions. Because requests and responses follow an agreed format, separate tools can work together.
What is a webhook?
A webhook is a message a service sends automatically to a URL you choose when something happens, so your tools can react right away without checking again.
What is OAuth?
OAuth is a standard way to let an app use your data in another service without giving it your password, limiting what it can do and for how long.
What is a CSV file?
A CSV file stores a table as plain text, with values separated by commas. Almost any tool can read and write it, so it's a common way to export and move data.
Account security
Passkeys and two-factor authentication: how sign-in stays safe.
What is a passkey?
A passkey is a way to sign in without a password. Your device keeps a private key, the site keeps the matching public key, and you have nothing to type.
What is two-factor authentication (2FA)?
Two-factor authentication (2FA) asks for a second, different kind of proof after your password, like an app code, so a stolen password alone isn't enough.
What is phishing?
Phishing is a scam that impersonates a real company to lure you to a fake site and steal your passwords or card details. Learn to spot it and what to do.
What is the principle of least privilege?
The principle of least privilege means giving each person or tool only the access they need for their work, so mistakes and break-ins do less damage.
