How I Write Prompts for AI (As Taught by Google)
The 4-Part Formula for Writing ChatGPT Prompts That Work
Massive AI prompts are off-putting to read, let alone use. The good news is you don’t need to write endless paragraphs of instructions, which are all the rage on social, to get good outputs.
I spent a dozen hours reading documentation from Google and Claude's prompt engineers. They provide a straightforward framework for crafting AI prompts.
An effective AI prompt has four essential parts.
Persona: Tell AI who it should be. This sets the tone and expertise level.
Task: Specify exactly what you want, with clear parameters.
Context: Share your goals and any relevant examples.
Format: Define how you want the output structured.
Here’s your fill-in-the-blank template to get started:
You’re a [role] who [key characteristic].
I need [specific task] for [target audience/purpose].
Here’s my [context/examples].
Please format the output as [desired format].
Here’s a before-and-after showing how this works:
WEAK PROMPT:
“Write me some good hooks for my creativity course.”
STRONG PROMPT:
“You’re a copywriter who specializes in viral LinkedIn content. I need 5 attention-grabbing hooks for LinkedIn posts about my journey as a creative professional adopting AI tools. My audience consists of professionals in creative industries who want to stay ahead of tech trends. Each hook should lead into a story about overcoming initial AI skepticism. Please format each hook as a single punchy sentence, numbered 1–5, with a brief explanation of why it would work well on LinkedIn’s algorithm.”
Another real example:
WEAK PROMPT:
“Help me write a blog post about AI tools.”
STRONG PROMPT:
“You’re a tech journalist who writes for creative professionals. I need a 1500-word article explaining how AI tools are enhancing (not replacing) creative work. My readers are professional writers and artists who want to stay competitive but are skeptical of AI. Include 3 specific case studies of creators successfully using AI. Format this as a long-form article with clear H2 headers, short paragraphs, and bullet points for key takeaways.”
The outputs from these prompts are usable. I don’t use them verbatim, though. I clean them up, add a personal take, one or two facts, or a story based on my experiences.
I break down how I use this approach here.
Pro tip: Run the same prompt through Claude and GPT and pick an output you like best.
