I will write a custom prompt for claude or chatgpt
Matt G.
About this gig
Tired of AI that almost gets it right? Need a prompt that actually does what you want not just on the first try, but every time?
I write custom prompts for Claude and ChatGPT that hold up under real use. Whether you need a one-shot prompt for a specific task, a system prompt that shapes how an AI behaves across sessions, or a full modular setup for complex workflows, I'll build it to fit what you're actually trying to do.
What you get:
- A custom prompt or configuration built around your specific use case
- Clear instructions on how to use it effectively
- Revisions included so we get it right
I work primarily with Claude (Anthropic) and ChatGPT (OpenAI), and I know how these systems succeed and fail. That means prompts that work the first time, every time; not template prompts that break under real conditions.
Not sure exactly what you need? Send me a message describing the problem you're trying to solve and I'll help you figure out the right scope.

Need precise instructions for AI systems, or prose that does the same job for people? Both come down to the same skill: figuring out what needs to be said and saying it with brevity.
I work primarily with Claude and know how these systems succeed and fail. That means prompts that follow your workflow instead of fighting it, architectures which hold up under real use, and writing that gets read rather than skimmed.
If you have a problem that's hard to articulate, or you've watched AI confidently miss the point, contact me. That's where I'm most useful.
FAQ
What information do you need from me to start?
A clear description of what you're trying to accomplish, the AI platform you want to use (Claude or ChatGPT), and any specific requirements or constraints. The more detail you give me upfront, the better the result.
Can you work with AI platforms other than Claude and ChatGPT?
I specialize in Claude and ChatGPT because that's where my expertise is deepest. I can build prompts for other major LLMs if needed, but the work will be most reliable on the two platforms I focus on.
What's the difference between a prompt, a system prompt, and a configuration?
A prompt is a single instruction for one task. A system prompt shapes how an AI behaves across an entire conversation or session. A configuration combines multiple coordinated prompts for sustained, complex use. The package you need depends on the scope of your problem. Message me if you're unsure.
How are revisions handled?
Each package includes a set number of revisions. If the first delivery doesn't fit what you needed, tell me what's off and I'll adjust. Most issues get resolved within one revision.
Can you guarantee the prompt will work exactly how I want?
No one can. AI systems are not fully deterministic. The same prompt can produce variable output. What I can guarantee is that I'll build the prompt to give you the best chance of reliable, repeatable results, and that I'll be straightforward with you about what these systems can and can't do.
