The LearnLLM AI knowledge base explains how to use AI tools such as ChatGPT and Claude responsibly in your work. You learn how the models work, where they fall short and how to check their output before you rely on it.
All articles are grouped into seven clusters. The buttons at the top take you straight to a cluster, and the latest articles are listed at the bottom.
What you will find in the AI knowledge base
The AI knowledge base has seven clusters, each with its own overview page. Below, each cluster has two articles that make a good starting point.
AI basics
The AI basics cluster covers the groundwork: what AI is, how language models work and which risks come with them. Start with what artificial intelligence is, then read how AI works.
AI models explained
AI models explained goes through the models one at a time: what each one is, what it can do and which tasks it suits. The cluster covers everything from ChatGPT and Claude to Gemini, Mistral and Copilot. Good starting points are what Claude is and which Claude model to choose.
AI tool comparisons
The AI tool comparisons help you choose based on real situations rather than feature lists. Read Claude vs ChatGPT for the two tools professionals weigh up against each other most often, or which AI is best for an overview by task.
Prompt engineering
In the prompt engineering cluster you learn to write instructions that work, with examples you can use straight away in your own work. Start with assigning a role in a prompt and, for multi-step tasks, move on to chain-of-thought prompting.
ChatGPT guide
The ChatGPT guide brings together practical explanations of plans, files, images and voice. Good starting points are what ChatGPT costs and how to upload an image to ChatGPT.
Claude guide
The Claude guide is about working with Claude day to day: Projects, Skills, Cowork in the chat and the plans. In our original Dutch knowledge base, the article on what Claude costs draws more visitors from Google than any other. Creating a Claude project shows how to set out your context once instead of repeating it in every conversation.
AI for business
The AI for business cluster treats AI as a shared way of working across an organisation: rules, risks and use by sector. Read what AI literacy is for an explanation of the obligation under the EU AI Act, or the sector guides on AI for accountants and AI for lawyers.
How to get the most from the AI knowledge base
The AI knowledge base works best if you start with the cluster that matches where you are now:
- New to AI: start with the basics; tool-specific guidance makes more sense after that.
- Undecided between tools: read the comparisons first.
- You already use a tool but do not trust the output: go to prompt engineering and the guide for your tool.
- You want to introduce AI in your team: start with AI for business.
Every article follows the same approach: understand where AI fails, pick one specific use, write instructions that work and build in checkpoints. From my years at major banks I bring the four-eyes principle: nothing goes out without a second check.
Since Google’s January 2026 update, I have seen in Search Console that generic AI explainers lost a lot of traffic on several sites. Content built on first-hand experience and practical examples held its ground. The articles here are written to that standard.
Want to do more than read? If you want to learn a tool step by step, an AI course builds a structured way of working around what you read here. Examples are the ChatGPT Course and the Claude Course. For a whole team there is AI training for teams.
