What is ChatGPT anno 2025?
ChatGPT is an AI platform built on GPT-4o, OpenAI's latest language and multimodal AI. The platform lets you:
Using text, images, voice and files in your conversations
Build custom GPTs with your own instructions, files and tone-of-voice
Manage projects where context is preserved across multiple sessions
Analyze files such as spreadsheets, PDFs, presentations
Save and share prompt libraries with your team
Where in 2022 you were still giving separate prompts, now you work with full workflows within ChatGPT.
The art of powerful prompts
Why prompts make the difference
A good prompt is like a well-worded briefing: the more specific, the better the output. Prompt engineering is the skill that determines how efficient and valuable your AI work becomes.
Prompt framework: RACE
A useful model for structuring prompts is the RACE model:
R = Role → Give the AI a role: "You are an experienced email marketer."
A = Action → What to do? "Write an AB test for a winback campaign."
C = Context → Who is the target audience, what is the product, what channel?
E = Examples → Give examples or show the desired style
Prompt hacks that work
Add "Think aloud" for more transparent output
Use bullets to force ChatGPT to structure
Let ChatGPT evaluate and improve its own answer
Working with Projects: holding context
One of the strongest features of ChatGPT Plus (with GPT-4o) is the use of Projects:
You create a project by customer, campaign or topic
You can add multiple documents, images or spreadsheets
ChatGPT remembers previous conversations within that project
Perfect for long-term strategic applications
Use scenarios:
Building a content strategy over 6 months
Preparing sales training by target audience
Generating all product descriptions for a new web shop
Pro tip: also use Projects to build presentations with a consistent style.
My GPTs: building your own AI assistant
With My GPTs, you can build your own ChatGPT version, complete with:
Instructions (who are you, what are you doing?).
A specific tone-of-voice
Uploaded documents
API calls or built-in tools
Examples of proprietary GPTs:
An "Email Expert GPT" who only writes email campaigns according to your style
