Summary
With my updated Custom GPT, I support turning vague ideas into precise, reproducible, and high-quality prompts. The focus is not on solving a problem itself, but on the clean structuring of tasks, context, and expectations – as a foundation for reliable AI results in professional use.
A lot has changed
Over the past months, I have repeatedly observed the same pattern in many conversations: Good results with generative AI rarely fail because of the model – but almost always because of the prompt. Unclear goals, implicit assumptions, and missing context lead to results that feel random.
This is exactly why I have recently revised my Custom GPT “Prompt of Prompts” (https://marc-widmann.de/prompt) more extensively.
What the Custom GPT is designed for
The Custom ChatGPT is not a problem solver, but a prompt architect. Its sole purpose is to help users develop clear, precise, and effective prompts for large language models – structured, iterative, and reproducible.
It is particularly suitable for:
- Consultants, project managers, and executives
- Users who regularly work with ChatGPT & similar tools
- Teams that require quality, comparability, and traceability of AI results
In short: everywhere prompts are working tools – not toys.
How the approach works
It follows a clearly defined process:
1. Clarifying the objective
First, it is clearly defined what the prompt is supposed to achieve – role, context, objective, and expected output.
2. Iterative improvement
Based on user input, three fixed elements are created:
- a revised prompt
- concrete improvement suggestions
- targeted follow-up questions to close gaps or clarify ambiguities
3. Structure instead of gut feeling
The final prompt follows a clear logic:
- Role / Perspective
- Context / Background
- Task / Objective
- Assumptions & Constraints
- Input
- Output format
- Optional quality criteria
4. Ready-to-use instead of explanatory text
The result is always a copy-ready, directly usable prompt – without meta-commentary or execution of the actual task.
Why this matters to me
In transformation and project contexts, it is not creativity for its own sake that matters, but:
- Clarity
- Repeatability
- Quality of results
A good prompt today is comparable to a well-defined requirement, a clear decision question, or a well-formulated management briefing.
Anyone who wants to use generative AI professionally must learn to lead precisely – including in the interaction with models. The updated Custom GPT supports exactly this: structured, factual, and effective: Custom GPT – “Prompt of Prompt” (https://marc-widmann.de/prompt)
