Output Format Control

Tell AI the structure, length and layout you want for its answer

The Problem

AI gives you 3 paragraphs when you wanted bullet points. Or a long essay when you needed a summary table. You spend time reformatting the output to make it usable.

The Solution

Explicitly specify the exact format you want in your prompt. Be precise about structure, headings, length, and layout.

"Provide your answer in this format: [specify exact structure]"

Before You Rely on This

The examples on this page are made up to show the technique. No test results have been published for it, so try it on your own work and judge it by what you find.

This guide is about how to word a prompt. It does not make a client's document or information safe to put into an AI tool. What you may enter depends on the plan your firm has, its agreement with the vendor and your firm's policy: Claude Projects for Client Matters sets out the checks for one tool. To practise, use a precedent or a published document that contains no client information, and refer to parties by role.

Why It Works

LLMs can generate content in virtually any format - they just need to know which one you want. By default, they produce prose paragraphs. Tell them otherwise and they'll comply.

Example Formats

Provide your answer in this format:

1. SUMMARY (3 bullet points max)

Keep the total response under 300 words.
