I'm Sergey Endrass. I show how to use AI for work, content, advertising and building your own projects — clearly, practically and without filler theory.
# A FAMILIAR PICTURE
It is almost never the model. It is that the model is missing exactly what you hold in your head and never say out loud.
"The answer looks right but feels empty"
The model returns an averaged solution because it knows neither your situation, nor your constraints, nor what a good result would look like.
"I don't know how to phrase it"
You stare at an empty input box and type the first thing that comes to mind. From there, the whole quality of the answer rests on that random sentence.
"I'm rewriting the request for the tenth time"
Every new attempt is guesswork. Without a system you cannot tell which edit improved the answer and which one spoiled it.
"I only use it for text"
Documents, spreadsheets, analysis, images, advertising, whole projects stay untouched — simply because it is unclear where to start.
"I start from scratch every time"
A good prompt was found, it worked, and it vanished into the chat history. A week later everything has to be rebuilt.
"I can't see how to apply this to my own work"
Other people's examples look convincing but do not transfer to your work, your niche and your project.
ChatGPT is not a toy. It is a proper working tool, provided you know how to steer it. The model does not read minds: it works only with what you wrote. Give it a role, the conditions and the shape of the answer — and you get a result you can actually use. Everything else stays guesswork.
# ABOUT ME
I have worked with ChatGPT since 2023 and use AI not for experiments but for real tasks: building websites and applications, developing projects, preparing content, advertising, images, documents and working processes.
I know how confusing ChatGPT can feel at the start. That is why my training is built on plain practice: we take a specific task, create the right context, assemble the prompt and bring the result to a usable state.
What I do in practice
# PROGRAMME
Each area ends not with notes but with something you keep using afterwards.
How the model reads your request, why similar wordings get different answers, and where its limits are. We go through the interface, modes, files and memory.
You understand how the model behaves and stop guessing.
# PROMPT BUILDER
The same task at four stages. The model does not change — what it receives as input does.
Task: a content plan for a small offline studio
The model knows neither your subject, nor your audience, nor how much time you have. It answers in averages — so that it fits everyone at once.
# HOW THE TRAINING WORKS
We do not work through a list of topics. We take the same route every time — until it becomes your working reflex.
We take not a textbook example but the thing you actually need to get done this week.
We gather the facts, limits and material without which the model fills in the gaps itself — and gets them wrong.
We build the prompt from blocks: role, task, limits, answer format. Each block owns its part of the result.
We look at what does not add up and fix the prompt — instead of rewriting the answer by hand every time.
We turn what we found into a template you keep using on your own.
# PRACTICAL SCENARIOS
The tasks people most often bring to the training. We work on yours, not on made-up ones.
Topics, formats and copy for a specific channel and the time you actually have.
Audiences, offers, ad variants and test hypotheses instead of one random piece of copy.
From structure and copy to a finished page — including work with Claude Code and Codex.
Style, palette, references and image generation that do not fall apart by the second post.
Break the idea into stages, build the structure and work out what comes first.
Contracts, reports, long material: pull out the substance, compare versions, find the gaps.
Tasks that repeat every week turn into a ready template with a prompt.
Which scenarios are included depends on the plan and your task — not all of them are part of every plan.
# PLANS
The difference between the plans is the depth of support, not the amount of theory.

Yes. We start with how ChatGPT is built and why it answers the way it does. No prior experience is needed — just a computer and a task you want to practise on.
