These courses are being updated with artificial intelligence. We try to stay at the front of what AI can do: the tools change, and the syllabus is revised so that what you learn still holds when you publish.

Lexema teaches AI prompt semantics: how to tell a tool what you want, what you do not want, and what each word in the brief means. A prompt is not a magic sentence. It is a short contract between a person and a model. If the words are ambiguous, the result is too. The course starts from real work — a page, a service, a message to a customer — and turns that work into a brief that can be repeated and reviewed.
It begins with intent. What has to come out: a draft, a list, a structure, a variant. What it must not invent: prices, dates, awards, names, guarantees. What context to give: area, tone, audience, business limits. The prompt is written in layers: goal, safe facts, prohibitions, output format and rejection criteria. A vague line such as “make it professional” is replaced with a concrete instruction: “use short sentences, name the village and do not promise deadlines”.
Semantics is practised by reading the result aloud. If a sentence could sit on any website in the trade, it is marked. If the model has shifted the meaning of a word in the brief, the prompt is corrected, not only the text. Synonyms that are not synonyms in a business are separated: “rental” and “cession”, “enquiry” and “quote”, “delivery” and “publication”. The student leaves a lexicon sheet: allowed words, words to avoid, and examples of a good brief and a bad brief.
Review is practised too. The model proposes. The person decides. What was accepted, what was discarded and why are noted. That memory stops the same mistake when the tool changes name or style. You practise asking for less: one clear block is worth more than three empty pages. If the result does not add a fact the business can stand behind, it is not used.
In about fifteen days a usable method is left: reusable prompts, a list of limits and a review routine. In a week the first well-written brief and its review fit. In a month the method is applied to several kinds of text and the business lexicon is settled. Lexema does not teach you to trick AI or to hide that a tool was used. It teaches you to ask with precision and not to publish what you do not understand.
