Claude vs ChatGPT: 10 examples of prompts for marketing - how to adapt to each model
Comparison of prompts for Claude and ChatGPT in marketing 2026. How Claude and ChatGPT read prompts differently, 10 examples with analysis for each model, decision matrix when to take which model. Claude Artifacts, Projects, ChatGPT Tasks, Custom GPTs.
I use Claude and ChatGPT every day. And he noticed: the prompt that Works great in ChatGPT, but produces garbage in Claude. And vice versa. Case not which model is better. The point is that they are designed in different ways.
I have been working with AI since 2024. Wrote several dozen via neural networks articles, dozens of prompts for client projects and our own templates that I reuse every week. Below is not a theory prompt engineering, but the practical difference that I identified during two years.
The main misunderstanding about Claude and ChatGPT: they think that the difference is who is smarter? The difference is how they read the prompt. Claude reads as a specification analyst. ChatGPT is like a copywriter brief.
1. How Claude and ChatGPT read prompts differently
Claude treats a prompt as a set of instructions. Each paragraph is a command. If you write “write a post and add a CTA at the end” - Claude will do exactly this: he will write a post and add a CTA at the end. Even if It makes more sense for a CTA to be in the middle.
ChatGPT treats the prompt as a conversational context. Same phrase “write a post and add a CTA at the end” - ChatGPT can interpret like “write a post that ends with a CTA” or “write a post that ends by including a CTA.” The spread is greater.
Practical conclusion: Claude's prompts require more precision. For ChatGPT - more context and examples.
2. Answer format: tabular versus narrative
Claude is the king of structured output. If you ask for a table comparisons on 5 parameters with 4 instruments - Claude will give an even table with headings, rows and correct columns. ChatGPT can make a table in markdown, but sometimes 3 columns instead of 4 or strange order of lines.
ChatGPT is better in narrative formats: social media post, newsletter, product description. Where style and tone of voice are more important, and not the scheme. Claude also knows how to write “lively”, but if you don’t specify the format - will write it as a report according to GOST.
This contrast is key when choosing a model. Details about what ChatGPT covers tasks in marketing, I looked into ChatGPT guide for marketers.
3. Context window: Claude multiple times larger
Claude has 200K tokens. This is War and Peace in its entirety + a couple more novels. GPT-4o has 128K tokens. In practice: Claude can hold in memory the entire history of the dialogue of 50 messages and do not forget that you requested in prompt No. 1.
I had a case: I uploaded an 80-page report (.pdf) to Claude, asked to pull out all the numbers for 5 channels into a table and write conclusions for each. Claude did it without a single edit. ChatGPT with the same the file began to lose context on page 40.
For marketing tasks this means: analysis of competitors, analysis big semantics, report processing - leave it to Claude. Short tasks, drafts, creativity - ChatGPT.
4. Claude Artifacts and Projects vs ChatGPT Tasks and GPTs
Claude and ChatGPT have add-ons that change the approach to prompts. Briefly about the key ones.
Claude Artifacts — Claude creates a document inside dialog: HTML page, Mermaid chart, table, SVG chart, React component. This is not just text, but a visual object. Useful for a marketer: Claude can draw a sales funnel, collect dashboard in HTML or make infographics.
Claude Projects - permanent projects with files context and instructions. Download the tone of voice guide once and the brand book - every new dialogue in the project remembers them. For regular working on a content plan is irreplaceable.
ChatGPT Tasks - scheduled asynchronous tasks. For example: every Monday at 9:00 send the top 5 news marketing. ChatGPT executes and sends the result. Free in Plus. This is convenient for monitoring, digests, and weekly reports.
GPTs (Custom GPTs) - custom versions of ChatGPT for task. Marketing GPT with downloaded product materials - works as a consultant for the entire team.
5. 10 examples of prompts for marketing with analysis
Below are 10 real prompts that I use. Everyone is adapted under Claude and ChatGPT. The difference is not accidental - it reflects the strengths sides.
| # | Problem | Claude (accent) | ChatGPT (accent) |
|---|---|---|---|
| 1 | Blog article | Structure, sections, output | Tone of voice, involvement |
| 2 | Competitor analysis | Table, 5 parameters | Brief conclusions, insights |
| 3 | Post for TG | Format, length, CTA | Sharpness, attention retention |
| 4 | Product Description | Characteristics, benefits, pains | Selling style, emotions |
| 5 | Brief for creativity | List of requirements, restrictions | Idea, options, tone |
| 6 | Email newsletter | Structure, subject, segment | Title, openness |
| 7 | Audience segmentation | Groups, criteria, matrix | Behavioral patterns |
| 8 | Translation while maintaining meaning | Accuracy, terms, context | Adaptation to culture |
| 9 | Product FAQ | JSON-LD format, structure | Answers in human language |
| 10 | Prompt for another AI | Exact instructions, examples | Brief, context, style |
Example No. 1 in expanded form. For Claude the prompt looks like this: “You are the editor of a B2B blog. Write an article on topic X. Format: title, lead (3 sentences), 5 sections with H2, conclusion (150 words). Requirements: numbers in each paragraph, without general phrases, style like a practitioner without academics. Length: 1500 words." For ChatGPT the same request: “Write an article about X. It’s for business owners. Write vividly without filler, with numbers. Approximate length 1500 words. Do it this way so that you want to read to the end.”
The difference is obvious: Claude writes according to structure, ChatGPT - according to mood. My complete collection of working prompts is in the article about 7 prompts I use every week.
6. When to take Claude, when to take ChatGPT: decision matrix
After two years of using both models, I have a simple system. Not “which model is better”, but “what task is which model”.
| Task type | Model | Why |
|---|---|---|
| Long analytical texts | Claude | Maintains structure, does not lose thought for 2000+ words |
| Short creative posts | ChatGPT | Better tone of voice, more variability |
| Code/HTML/SVG | Claude | More precise syntax, less hallucinations |
| Translation and localization | ChatGPT | Better cultural adaptation |
| Analysis of large documents | Claude | 200K context vs 128K |
| Ideas and brainstorm | ChatGPT | More options, less formulaic |
| Structured data (JSON, tables) | Claude | Exact format, no extras |
| Selling texts | ChatGPT | Better sense of audience tone and context |
If you have a team of one, use both models. I divided my pipeline like this: Claude - article writing, analysis, structuring. ChatGPT - TG posts, newsletters, creative ideas. This speeded up the work by ~40% versus using one model.
By the way, I have about the “one marketer with AI” pipeline separate material — there I count how many roles AI replaces and in what amounts it converted.
7. What doesn't work: typical failures
1. Copy the prompt from ChatGPT to Claude without changes.You are guaranteed to get a different result. ChatGPT prompts are too much colloquial for Claude. Claude prompts are too dry for ChatGPT.
2. Write “write something marketing.”Claude will produce a 10 sentence paragraph with common phrases. ChatGPT will return 5 options, but none of them will work. Specific task + format = specific result.
3. Use only one model.On my projects, the Claude + ChatGPT combination gives 30-40% results better than each individually. They are not competitors, but different tools. Like a knife and fork.
4. Don't give the model feedback.Claude learns from your refinements faster than ChatGPT. After 3-4 corrections Claude writes noticeably better in the desired style. ChatGPT is changing more slowly.

8. Conclusion
The difference between Claude and ChatGPT is not who is smarter. The difference is architecture of prompts. Claude - specification. ChatGPT - brief. Write prompts based on this, and not on general ratings. Use both models in parallel: Claude - for structure and analysis, ChatGPT - for creativity and tone. Test it. Adapt. Don't be lazy to write two prompts instead of one - this pays off in the quality of the output.
