ChatGPT vs. Claude: Which AI Writes Better Prompts?

AI for Marketing Agencies and Prompt Engineering for efficiency

✍️ Introduction: ChatGPT, Claude, and the Modern Marketer’s Dilemma

You’re juggling social media calendars, email campaigns, SEO, and maybe even a podcast script—all before lunch. You know AI can help, but here’s the catch: the output is only as good as the prompt you feed it.

Sound familiar?

If you’ve ever typed “Write a blog post about email marketing” into ChatGPT and ended up with something… meh, you’re not alone. Marketers everywhere are realizing that prompt engineering isn’t just a tech nerd hobby—it’s a competitive edge.

But here’s the new question: with so many AI tools available, should you be prompting with ChatGPT or Claude? And more importantly, which one helps you write better prompts, especially when your content calendar can’t wait?

Let’s break it down.


🤖 ChatGPT vs. Claude: A Quick Comparison for Marketers

Both ChatGPT (from OpenAI) and Claude (from Anthropic) are powerful large language models, but they handle prompts a little differently. If you’re looking to generate marketing-specific content quickly and efficiently, here’s what you need to know:

FeatureChatGPT (GPT-4)Claude 3
Prompt InterpretationDirect and efficientContext-aware, nuanced
Tone ControlEasy to steerMore natural by default
Long Prompt HandlingExcellent with structured promptsBetter with large context windows
Strengths for MarketersSEO writing, social captions, email templatesBrand voice mimicry, customer support scripts
WeaknessesSometimes robotic with generic promptsCan over-interpret vague prompts

💡 Pro Tip: ChatGPT works best with structured, goal-oriented prompts. Claude shines when you want a softer, more human tone.


📚 Framework: Writing Better Prompts for Marketing Use Cases

Instead of asking “Which AI is better?”, a smarter question is: “How can I write better prompts no matter which AI I use?”

Here’s a simple 3-part framework we recommend at My Magic Prompt:

1. Define the Role

Set the stage: “Act as a SaaS marketing strategist” or “You’re a copywriter with 10 years of B2B experience.”

2. Clarify the Goal

What do you want? A tweet thread? A blog intro? A Google ad headline?

3. Set the Format & Style

Add parameters like tone, word count, or audience: “Write in a witty, Gen Z-friendly tone for startup founders.”

Example:

Prompt:
You’re a seasoned content strategist for a B2B SaaS tool. Write a 500-word blog post intro on AI for marketers. Make it friendly, informative, and slightly aspirational.

This kind of prompt performs well in both ChatGPT and Claude, though Claude may give you more contextually rich output, while ChatGPT responds faster with clear formatting.

❓ FAQ: Common Questions About AI Prompting for Marketers

What’s the difference between a good and bad AI prompt?

A good prompt is specific, structured, and contextual. A bad prompt is vague, overly broad, or lacks direction. Think of it like giving your intern a task—clear guidance always wins.

How can I organize my prompts better?

Use a prompt management tool (like My Magic Prompt’s Prompt Library) or a simple Notion board categorized by use case—emails, blog content, social, etc.

Should I use the same prompt in both ChatGPT and Claude?

Yes! Testing across tools reveals strengths and weaknesses. You might find ChatGPT excels at outlines, while Claude shines in tone-rich copywriting.

Which AI is better for brand voice?

Claude is often better at maintaining a consistent, natural brand voice. ChatGPT can follow tone instructions but sometimes sounds formulaic unless finely tuned.

Can AI help with SEO?

Absolutely. ChatGPT is particularly good at structuring SEO content. Use targeted prompts like: “Create a blog outline for the keyword ‘Best ChatGPT prompt templates for marketers.’”

Do I need to be technical to use AI well?

Not at all. Tools like My Magic Prompt are designed for non-technical users. If you can write a creative brief, you can write a powerful AI prompt.


🤍 Final Thoughts: It’s Not About the Tool—It’s About the Prompt

Whether you choose ChatGPT for its structure or Claude for its nuance, one thing’s clear: your prompt is the lever that moves the AI engine.
