How to give AI examples: few-shot prompting for beginners

Some things are hard to describe but easy to show. You might struggle to explain your writing style in words, but you can paste three emails you've written. You might not know how to describe the exact format you want, but you have a sample from last month. Giving the AI examples is one of the most reliable ways to improve results, and it has a slightly technical name: few-shot prompting.

"Shot" just means example. A "zero-shot" prompt gives no examples. A "one-shot" prompt gives one. "Few-shot" means a handful, usually two to five. You don't need to remember the terms; the idea is simply: show, don't just tell.

Why examples work so well

When you describe what you want ("friendly but professional"), the AI has to interpret your words, and its interpretation might differ from yours. An example removes that guesswork. It shows length, tone, vocabulary, structure, and formatting all at once, including details you might not think to mention.

The basic few-shot template

The final line is important. Without "don't copy their content", the AI sometimes reuses phrases or ideas from your examples too closely.

Use case 1: Matching your writing voice

This is the most popular use for everyday users. If AI drafts sound stiff or generic, paste a few things you've written and ask it to write the way you do.

Asking the AI to describe your style first has a bonus: you can save that description and paste it into future prompts, even when you don't have examples handy.

Use case 2: Getting a consistent format

When you need several outputs that look the same (meeting notes, product listings, weekly updates), an example is far clearer than a description.

Use case 3: Sorting or labeling things

Examples are great for teaching the AI how you categorize things, such as sorting expenses, tagging customer feedback, or classifying emails.

That last instruction ("mark it Unsure") is a good habit any time you ask AI to sort things. It surfaces edge cases instead of quietly misfiling them.

How many examples should you give?

• One is often enough for tone or a simple format.
• Two or three is a good default. They help the AI see what's consistent across examples and what varies.
• More than five rarely helps for everyday tasks and makes your prompt long.

Choose examples that are genuinely good and reasonably varied. If all your examples are about the same topic, the AI might think the topic is part of the pattern.

Common mistakes with examples

Examples that contradict your instructions. If you say "keep it under 50 words" but your examples are 200 words, the AI may follow the examples. Make them consistent.

Using bad examples. The AI will copy weaknesses as faithfully as strengths. Pick your best work.

Pasting private information. If your example emails include names, addresses, or confidential details, remove or replace them before pasting.

Forgetting to say what to copy. Be clear whether you want the AI to match tone, format, length, or all three.

Combining examples with the rest of the formula

Few-shot prompting works best alongside the other basics: a clear task, context, and a stated format. You can think of examples as a powerful version of the "format" and "tone" parts of the 5-part prompt formula. Pair them with a role (see role prompting) for even more control.
