ChatGPT masterclass 2025: from beginner to AI expert in one guide
ChatGPT training for entrepreneurs is becoming increasingly important in 2025. This complete ChatGPT guide teaches you the essential AI techniques to turn ChatGPT into a powerful business assistant that saves time and delivers better results. Whether you are a small business owner in Belgium or a marketer who wants to learn how to use ChatGPT - this masterclass offers practical ChatGPT tips for directly applicable results.
“AI will not take over your job, but someone who uses AI will.”
For entrepreneurs, this means: learning to work with AI tools like ChatGPT is no longer a luxury, but a necessity.
Why most entrepreneurs use ChatGPT incorrectly
“Write a blog post about marketing” yields generic rubbish. Successful ChatGPT users in Belgium and the Netherlands think differently: they provide context, specify their target audience, and ask for concrete output. The difference between weak and effective ChatGPT prompts determines whether you spend 10 minutes or 2 hours on the same result.
As writing better prompts already explained: the quality of your ChatGPT input determines the quality of your output. But how do you ensure better AI prompts for your Dutch business?
The CLEAR system for better prompts
Forget complicated frameworks. For daily use, CLEAR is sufficient:
C - Context: Provide background information about your situation
L - Length: Specify how long/short you want the output to be
E - Expertise: What role should ChatGPT assume?
A - Action: What exactly needs to happen?
R - Result: What does success look like?
This system builds on the RACE model for ChatGPT prompts, but is easier to apply for daily business tasks.
Example of a weak prompt:
"Write an email for customers"
Example of a strong prompt:
"You are a customer service expert. Write a friendly but professional email (150 words) to customers who receive their order late. Explain that there is a delay due to high volume, offer a solution, and maintain goodwill. The tone should be understanding without being overly apologetic."
Five ChatGPT techniques you can apply today
1. The expert committee
Have ChatGPT provide multiple perspectives:
"Give advice on our new pricing strategy from three roles:
A marketer focused on customer value
A CFO looking at margins
A sales manager who needs to close deals
Compare their advice and give a balanced recommendation."
2. The step-by-step plan method
For complex projects:
"Create a step-by-step plan to double our Instagram followers in 6 months. For each step, provide specific actions, timeline, and expected results."
3. The improvement cycle
Have ChatGPT check itself:
"First, write a product description for our new software. Then evaluate it for persuasiveness and clarity. Rewrite it to a version that scores better."
4. The persona approach
For targeted content:
"Write as Mark, 38 years old, owner of a webshop with 50 products. He wants to sell more but has limited budget and time. Write from his frustrations about complex marketing tools."
5. The format template
For consistent output:
"Create a weekly newsletter with this structure:
Opening line (personal)
Main tip (1 paragraph)
Tool recommendation (short review)
Inspirational quote
Call to action"
Custom GPTs: your personal AI assistants
Custom GPTs are ChatGPT versions that you train for specific tasks. Think of a copywriter who knows your tone of voice, or a data analyst who understands your reports.
“Custom GPTs have helped us to triple our content production without loss of quality.”
Three GPTs that every entrepreneur should have:
1. Content Creator GPT
Upload your best content, style guide, and target audience information. This GPT writes blogs, social posts, and emails in your style.
2. Strategy Advisor GPT
Add your business plan, market analyses, and previous strategies. Ideal for brainstorming new initiatives.
3. Customer Service GPT
Train with frequently asked questions, product information, and your communication style. Perfect for draft answers to customer questions.
How to build an effective Custom GPT:
Start specific: "Email marketing expert for B2B software" works better than "Marketing expert"
Upload relevant documents: Tone-of-voice guide, successful campaigns, customer feedback
Test with real scenarios: Try different prompts and refine the instructions
Update regularly: Add new insights and examples
Practical applications per business component
Marketing and content
Social media planning: "Plan 30 LinkedIn posts for this month around the theme of 'productivity for entrepreneurs'"
Blog ideas: "Generate 10 blog topics that help our target audience with [specific problem]"
Email sequences: "Write a 5-part welcome sequence for new newsletter subscribers"

Sales and customer contact
Personalize offers: "Rewrite this standard offer for a tech startup that wants to grow quickly"
Follow-up emails: "Write a friendly reminder email for customers who have not responded to the offer"
Handle objections: "Give 3 ways to respond to 'you are too expensive'"
These techniques combine excellently with traditional performance marketing strategies for a complete sales approach.
Operations and efficiency
Document procedures: "Turn this phone conversation into a step-by-step guide"
Summarize meetings: "Make a short summary with action points from these minutes"
Training materials: "Develop a checklist for new employees in customer service"
Projects: maintain context
ChatGPT Projects save your conversations and documents per topic. This way you build up knowledge that ChatGPT remembers:
Per client: All communication, briefs and output in one project
Per campaign: From planning to evaluation
Per quarter: Strategic planning and progress
Pro tip:
Upload at the beginning of each project:
Your house style guide or tone-of-voice document
Information about your target audience
Examples of previous work that performed well
Common mistakes and how to avoid them
Mistake 1: Too vague prompts
Bad: "Help me with marketing"
Better: "Give 5 concrete actions to generate more leads for my web design agency"
Mistake 2: Not giving context
Bad: "Write a newsletter"
Better: "Write a monthly newsletter for owners of small restaurants about trends in the hospitality industry"
Mistake 3: Not checking output
Always read what ChatGPT produces. Correct errors, add personal details and adapt to your situation.
Mistake 4: No iteration
If the initial output isn't perfect, provide feedback: "Make the tone more professional" or "Add more concrete examples."
Advanced tips for better results
Upload files strategically
ChatGPT can analyze PDFs, Word documents, and spreadsheets. Upload your best content as a reference for new projects.
Combine with other tools
Notion: For organizing ChatGPT output
Canva: For visualizing ChatGPT concepts
Google Sheets: For data analysis by ChatGPT
For e-commerce, you can also combine ChatGPT with Shopify AI apps and automations for a complete digital workflow.
Build a prompt library
Save successful prompts in a document. This way, you don't have to rethink how to ask something every time.
The future: AI as a strategic partner
Companies that strategically deploy ChatGPT gain a competitive advantage:
Speed: Develop ideas within minutes
Consistency: Always the same quality output
Scalability: More content without extra staff
Creativity: New perspectives and ideas
“Companies that strategically deploy AI see an average of 15% productivity gains within the first year.”
