Design briefs: a template for humans and AI alike

A brief is the cheapest part of any design job and the one that decides how many rounds of changes follow. Here is a template short enough to fill in and complete enough to trust.

The short version

  • A design brief is a short document that sets out what a design must achieve, for whom, with which words, in which formats and by when.
  • A good design brief fits on one page and separates fixed facts from open choices.
  • The same brief works for a human designer and an AI, as long as the words, formats and definition of done are written out exactly.
  • Briefs for AI need fewer reasons and more exact facts, because an AI often guesses where a person would ask.
  • Keeping your brand rules in a brand kit lets every brief stay short.

A design brief is a one page note that tells a designer what to make: the goal, the audience, the exact words, the formats and sizes, the brand rules, the deadline and what counts as done. Written well, it works just as well for a freelance designer as for an AI designer, because both fail in the same place: the gaps. Below is a template you can copy, a filled example and the small differences between briefing a person and briefing an AI.

What a design brief is for

A brief does three jobs. It makes you decide what you want before anyone starts, it gives the designer everything they need in one place, and it becomes the yardstick for feedback. When a draft comes back, you check it against the brief rather than against a feeling. Most rounds of changes trace back to something the brief never said.

AUDIENCE
Who sees it, where, and for how long?

OPEN CHOICES
What the designer may decide:

DONE MEANS
What is delivered, in which file types, checked how:
Paste this into a document, an email or an AI chat. Delete any section that genuinely does not apply.

Two sections do most of the work. Words should be final, not "something about the sale", because rewriting copy after layout means redoing the layout. Open choices tells the designer where their judgement is welcome, which is the difference between a collaborator and someone following instructions.

Specific beats polite. Every entry in the right column produces a guess.

For formats, use the platform's real upload size rather than a description. Social media image sizes lists them all. For feeling, a place or an object ("like a printed concert ticket") is far easier to act on than adjectives, as design by describing explains.

A filled example

Here is the template completed for a small studio announcing a class. Notice how short each answer is.

  1. 1

    Project and goal

    Northside Yoga, new 7am class. Due Friday, approved by Sam. Goal: get regulars and newcomers to book the first session.

  2. 2

    Audience

    Office workers nearby, seeing it on Instagram while scrolling, for about a second.

  3. 3

    Words

    Headline "New 7am class." Detail "Mondays and Thursdays, from 12 October." Call to action "Book in the app."

  4. 4

    Formats

    Instagram post 1080×1350, story 1080×1920, Google Business post 1200×900.

  5. 5

    Brand, feeling and open choices

    Use the brand kit. Calm, early, unhurried. The designer chooses layout and whether to use a photo.

  6. 6

    Done means

    Three PNG files, the date checked against the timetable, approved by Sam.

New 7am class.
Mondays and Thursdays, from 12 October

The post the brief describes: exact words, one headline, calm.

New 7am class.
Book in the app

The story from the same brief, with the call to action taking the detail line.

Instagram post

1080 × 1350

Story

1080 × 1920

Google Business post

1200 × 900

The three deliverables from the example, to scale. Listing exact sizes in the brief removes a whole round of questions.

Common design brief mistakes

  • Draft copy. "Words to follow" guarantees a second layout. Send final words or wait.
  • Too many goals. One piece of design can do one job well. Split a brief that asks for awareness, sales and sign ups at once.
  • Moodboards with no notes. Ten reference images say ten different things. Write one line under each saying what you like about it; brand moodboards shows how.
  • No approver. If three people can say no, name the one who says yes.
  • Missing sizes. "For social" becomes a guess. List each format and its pixels.

Agencies that brief freelancers or clients all week tend to keep this template as a shared document and copy it per job; design agency workflow covers that rhythm.

Briefing a person versus briefing an AI

A human designer

  • Benefits from the why behind each choice
  • Will ask when something is unclear
  • Can be trusted with wide open choices
  • Reads a moodboard well

An AI designer

  • Benefits most from exact facts and limits
  • Often guesses rather than asks
  • Does best with one or two open choices
  • Needs brand rules stored where it can read them

The template above serves both. For a person, add a sentence of reasoning under the goal. For an AI, cut the reasons, keep the facts and make Done means strict, including "do not publish" if the AI is connected to tools that could. AI agents for design covers briefs for assistants that work through several steps alone.

Keep briefs short with a brand kit

The Brand section is the one that bloats. Rather than repeating fonts, colours and tone in every brief, store them once. A written brand style guide does this for people; for AI, the rules need to live where the tool can read them, as brand guidelines for AI explains.

In Gradiently, the brand kit holds your logos, palettes, heading and body fonts, voice, audience and what the brand does. The Designer, Gradiently's AI, reads it, asks for anything the brief left out, writes in your voice and lays the design out on your Mark, the living background that becomes yours alone once you claim it. Your brief shrinks to the goal, the words, the formats and what done means.

Check the brief before you send it

Read it as if you knew nothing about the project. Anything you would have to ask about is a gap; fill it now, not in round two.

Questions people ask

What should a design brief include?

The goal, the audience, the exact words, the formats and sizes, the brand rules, the feeling, the choices left open, the deadline and what counts as done.

How long should a design brief be?

One page is enough for most jobs. If it runs longer, move brand rules into a brand kit or style guide and refer to it.

Can I use the same brief for an AI designer?

Yes. Keep the exact words, formats and definition of done, and cut the background reasoning, which an AI uses less than a person does.

What is the difference between a creative brief and a design brief?

A creative brief usually sets the strategy and message for a whole campaign. A design brief turns that into specific pieces, with words, formats and sizes.
