Prompt Engineering: Write prompts that get reliable results from any AI, from everyday chats to context engineering, explained for beginners. It is a 55-page illustrated PDF from the oJAYo team, written in plain language and up to date for 2026.
A prompt is what you type to an AI. Prompt engineering is the skill of writing prompts, and arranging the information around them, so the AI gives you useful, reliable results. It is one of the fastest-growing search topics of 2026: Google reported that searches for “prompt” in South Africa rose 1,200% in a year, and similar interest shows up worldwide.
Some say prompt engineering is no longer needed because models are smarter. In practice the opposite is true at work: clearer requests still get better results, and as people build assistants, agents and team workflows, the skill has grown into context engineering, deciding everything the AI sees, not just the words of one request.
