How to Write Better Prompts for Claude and ChatGPT
Most disappointing AI responses come from vague prompts, not weak models. Here’s a repeatable method for writing prompts that get useful answers on the first try.

Steps
Step 1: State the Goal, Not Just the Task
Instead of “write an email,” say “write a short email asking my landlord to fix a leaking faucet, polite but firm.” The goal and tone context change the output dramatically.
Step 2: Give the Model Relevant Context Up Front
Paste in the actual document, code, or background details you’re working with rather than describing them from memory — models perform much better with source material directly in the prompt.
Step 3: Specify the Format You Want Back
If you want a table, bullet list, or specific word count, say so explicitly. Models default to prose unless told otherwise, which often isn’t what you actually need.
Step 4: Ask for One Task at a Time on Complex Requests
For multi-step work, break it into a sequence of prompts rather than one giant request — this makes it easier to catch and correct errors early instead of discovering them at the end.
Step 5: Iterate Instead of Starting Over
If the first response is close but not quite right, tell the model specifically what to change rather than rewriting your original prompt from scratch — this preserves useful context from the first attempt.
Tips
- ✅ Save prompt templates that work well for recurring tasks (emails, summaries, code reviews).
- ✅ Ask the model to explain its reasoning briefly if you need to verify a factual claim.
- ✅ Use explicit constraints (“under 150 words,” “no bullet points”) when format matters.
Warnings
⚠️ Always verify factual claims, statistics, or citations an AI model provides — models can generate plausible-sounding but incorrect information.
Q&A
Does prompt length matter?
Not directly — a longer prompt with relevant context usually outperforms a short vague one, but padding with irrelevant detail doesn’t help.
Is there a difference in prompting Claude vs. ChatGPT?
The core principles (clear goal, context, format) apply to both, though each model has slightly different strengths worth testing for your specific use case.
