We ran 100 of the most common AI prompts through PromptIQ Pro — the kind of prompts people type every day on Claude, ChatGPT, and Gemini. The results were sobering: 62% scored below 55 (a D or F grade). Not because the tasks were hard. Because the prompts were missing almost everything the AI needs to do its job well.
Here’s what we found, and more importantly, how to fix it.
The F-grade prompts
The lowest scorers had two things in common: they were short, and they had no structure. Here are some real examples (paraphrased):
- “Write me an essay about climate change.”
- “Summarise this.”
- “Give me some marketing ideas.”
- “Explain machine learning.”
These aren’t bad requests. They’re bad prompts. The task is clear enough to the person typing it, but from the model’s perspective, almost every decision is left open. Who is the essay for? How long? What angle? What format? What level of technical depth? The model has to guess — and when it guesses wrong, you get a generic, forgettable output.
What the A-grade prompts had
A-grade prompts (85+) consistently had five things:
- A role — “Act as a sustainability consultant” or “You are an experienced copywriter”
- Context — Background that narrows the problem space
- A clear task — Specific action verb, not just a topic
- Format specification — Length, structure, bullet points, JSON, etc.
- An audience — Who this output is ultimately for
When all five are present, the model doesn’t have to guess. It has enough structure to produce something you’d actually use without editing it three times.
The 30-second fix
Take the “write me an essay about climate change” prompt. Here’s the same request, restructured in 30 seconds:
You are an environmental journalist writing for a general audience. Write a 500-word explainer on how climate change is affecting agricultural supply chains in Southeast Asia. Use plain language, avoid jargon, and end with two concrete things an individual can do. Format as a short article with a compelling opening line.
That prompt scores 91 in PromptIQ Pro. The first one scores 12.
The content of the request is almost identical. The difference is specificity — role, context, format, audience, and a constraint (no jargon, concrete ending). Each of those additions takes about five seconds to type, and each one meaningfully narrows what the model has to guess.
Use “Fix My Prompt” when you’re in a hurry
PromptIQ Pro’s Fix My Prompt feature does this automatically. It takes your original prompt and rewrites it with bracketed placeholders for every missing element:
You are a [role]. Write a [length] [format] about [specific topic] for [audience]. The tone should be [tone]. End with [conclusion type].
Fill in the brackets in 20 seconds and you’ve turned an F-grade prompt into an A. That’s the entire workflow: type rough, fix fast, send strong.
