AI, for real — not in theory.
Generative AI is changing how every team works. Mastering it is no longer optional, whatever your role.
This domain starts from LLM foundations and prompting, up to expert use of ChatGPT, Claude and Gemini — with a toolbox kept up to date.
Cross-cutting by nature, it's the domain every leader — in marketing, data or finance — benefits from owning first.
The learning path
AI Essentials
Progressive modules, each closed by a checkpoint. Your progress is saved.
AI & LLM foundations
What AI, machine learning, and large language models actually are, how they work at a topline level, and where their capabilities end.
BLOCK 02Prompt engineering
The practical craft of getting great results: structuring prompts, giving examples, asking for step-by-step reasoning, and iterating fast.
BLOCK 03AI in daily work
Turning AI into a genuine productivity multiplier for writing, analysis, research, and admin, plus the judgment to know when not to use it.
BLOCK 04Responsible & trustworthy AI
Using AI safely and ethically: bias, verification, confidential data, copyright, and the topline of AI governance and the EU AI Act.
BLOCK 05Building with AI
How to structure an AI project, navigate the tools landscape (RAG, agents, vector databases, APIs), write basic code, and evaluate outputs against cost and latency.
BLOCK 06ChatGPT & the OpenAI ecosystem
A deep, hands-on mastery path for ChatGPT: models and Projects, Custom GPTs, Actions and Connectors, data analysis and multimodal, Codex and Canvas, agents, the OpenAI API, automation, and a capstone.
BLOCK 07Claude & the Anthropic ecosystem
A deep, hands-on mastery path for Claude: models and Projects, connectors, Skills, MCP, Claude Code, GitHub workflows, the Anthropic API and Agent SDK, automation, and a capstone.
BLOCK 08Gemini & Google AI
A deep, hands-on mastery path for Gemini: models and the app, Gems, Workspace, Extensions, AI Studio and the Gemini API, Gemini CLI and Code Assist, agents, Vertex AI, automation, and a capstone.
The feed
What's moving, right now.
Why your RAG system keeps failing in production
Most enterprise RAG deployments look impressive in demos and underperform in real workflows. Understanding exactly where they break, and why, is what separates teams that get lasting value from those stuck in an endless pilot loop.
AIChatGPT, Claude and Gemini: how to pick the right tool for actual work
Most professionals using AI assistants in 2026 are still defaulting to one tool out of habit rather than fit. Understanding what each of the three dominant platforms does distinctly well changes both the quality of your outputs and the time you spend getting there.
AIWhat LLMs actually are, and why the architecture still matters in 2026
Most professionals using AI tools in 2026 have no idea what is actually happening inside them. Understanding the core mechanics of large language models does not require a PhD, and it changes how you use these systems productively.
The tools
From theory to a real decision.
Skills, MCP, connectors and repos for Claude, ChatGPT and Gemini — a curated, up-to-date library.
