Client Testimonial Quote Card Prompt for Coaches

A glowing client review is the most persuasive thing you own, and most coaches let it die in a screenshot folder. The problem isn’t a lack of proof, it’s turning that proof into something people actually stop to read in the feed.

This prompt builds testimonial graphics for coaches the smart way. Instead of fighting a design app, you hand the AI your client’s words, your brand colors, and the platform, and it writes a precise image-generation brief you paste straight into DALL-E, Midjourney, or Gemini. By the end of this page you’ll also understand why the brief is structured the way it is, so your next graphic comes out cleaner.

When to use this

• A client just sent you a heartfelt review and you want to post it today.
• You’re building a “results” highlight reel or a social proof carousel.
• You want every testimonial to look on-brand instead of a random screenshot.
• You’re refreshing a sales page or pitch deck and need consistent quote cards.
• You want a few layout options to test without opening Canva.

The prompt

Copy this whole block into ChatGPT, Claude, or Gemini:

You are an expert brand designer who creates social proof graphics for coaches. Your job is to write a single, precise image-generation brief for a client testimonial quote card that I can paste straight into an AI image tool (DALL-E, Midjourney, or Gemini image).

Before writing, ask me up to 3 clarifying questions if anything below is unclear. Otherwise, proceed.

CONTEXT
- My niche: {{COACH_NICHE}}
- The client testimonial (use these exact words, lightly trimmed for length if needed): {{QUOTE}}
- Attribution to show: {{CLIENT_NAME}}
- My brand colors: {{BRAND_COLORS}}
- Where I'll post it: {{PLATFORM}}
- The mood I want: {{VIBE}}

TASK
Write ONE image-generation prompt that describes a testimonial quote card with:
1. The exact platform dimensions and orientation stated up front.
2. A clear layout: the quote as the hero element, attribution underneath, and a small space for my logo.
3. The brand colors used deliberately (name which color is background, which is text, which is accent).
4. A typography direction (a readable serif or sans pairing, with the quote large and the attribution smaller).
5. A simple, uncluttered composition with generous margins so the text is legible on a phone.
6. The mood and niche reflected in any background texture or shape, without busy stock-photo clutter.

CONSTRAINTS
- Keep the spelled-out quote text inside the prompt in quotation marks so the tool renders it verbatim.
- No fake logos, no watermarks, no human faces unless I ask.
- High contrast between text and background for accessibility.
- Describe a flat, modern design, not a 3D render or photo collage.

Then output, in this order: (a) the ready-to-paste image prompt in a single block, (b) one alternative version with a different layout, and (c) a one-line note on what text I should overlay manually if the AI tool struggles to render the words.

How to customize it

Replace the six {{VARIABLES}} before you send it:

Here is the exact prompt, filled in for a career coach. This is the whole input, nothing hidden:

You are an expert brand designer who creates social proof graphics for coaches. Your job is to write a single, precise image-generation brief for a client testimonial quote card that I can paste straight into an AI image tool (DALL-E, Midjourney, or Gemini image).

Before writing, ask me up to 3 clarifying questions if anything below is unclear. Otherwise, proceed.

CONTEXT
- My niche: career coaching for mid-career women in tech
- The client testimonial (use these exact words, lightly trimmed for length if needed): I went into three interviews calm and got two offers. I have never felt this prepared.
- Attribution to show: Priya M., Senior Product Manager
- My brand colors: deep teal #0F4C5C, warm cream #F4EFE6, soft gold accent
- Where I'll post it: Instagram feed, 1080x1080 square
- The mood I want: calm, premium, trustworthy

And here is the complete output the model returns:

(a) Ready-to-paste image prompt

A flat, modern testimonial quote card, 1080x1080 square, Instagram feed format. Calm, premium, trustworthy mood for a career coaching brand. Background: warm cream (#F4EFE6) with a single soft, subtle deep-teal arc curving along the bottom-right corner as a quiet accent. The quote is the hero element, centered with generous margins, set in a large elegant serif in deep teal (#0F4C5C): "I went into three interviews calm and got two offers. I have never felt this prepared." Below the quote, separated by a short soft-gold horizontal line, the attribution in a smaller clean sans-serif, deep teal: "Priya M., Senior Product Manager". A small empty rectangular space reserved in the bottom-left corner for a logo. High contrast, lots of breathing room, no human faces, no watermark, no busy textures. Minimalist editorial design.

(b) Alternative layout

A flat, modern testimonial quote card, 1080x1080 square, Instagram feed. Calm, premium mood. Background: solid deep teal (#0F4C5C). A large soft-gold opening quotation mark sits top-left as a graphic anchor. The quote text in warm cream (#F4EFE6), large readable sans-serif, left-aligned with wide margins: "I went into three interviews calm and got two offers. I have never felt this prepared." Attribution below in soft gold, smaller: "Priya M., Senior Product Manager". Small reserved logo space, bottom-right. High contrast, clean, no faces, no watermark, no clutter.

(c) Manual overlay note: If the tool garbles the words, generate the background and arc only, then add the quote and “Priya M., Senior Product Manager” yourself in Canva using a serif at ~64px for the quote and ~28px for the attribution.

That is ready to drop into your image tool. Generate, check the spelling of the rendered text, and if a letter is off, use the option (c) fallback.

Why this works

Three LLM principles are doing the heavy lifting here. Learn them and every prompt you write gets better:

1. Role priming. The opening line (“You are an expert brand designer who creates social proof graphics for coaches”) tells the model which slice of its knowledge to use. “Make me a quote card” pulls from the bland average of the internet; assigning a designer role pulls from layout, contrast, and typography conventions that actually look professional.
2. Specificity in, specificity out. The brief never says “use nice colors.” It says which color is the background, which is the text, and which is the accent, with hex codes. An image model can only honor what you name explicitly. Vague input produces a generic card; naming the layout, the type sizes, and the margins produces a card you’d actually post.
3. Constraints are quality control. The “no faces, no watermark, flat design not a 3D render, high contrast for accessibility” lines each kill a specific failure mode AI image tools fall into. Telling the model what NOT to do is as powerful as telling it what to do. And the “ask me up to 3 clarifying questions first” line lets it close gaps by asking instead of guessing, which is the single biggest fix for generic results. The verbatim-quote-in-quotation-marks instruction is a small trick that meaningfully improves how reliably the words render.

Do this now

1. Copy the prompt above into ChatGPT, Claude, or Gemini.
2. Replace the six variables with your real niche, the client’s exact words, your colors, and the platform.
3. Send it. If it asks clarifying questions, answer them, then paste the brief it writes into your image tool.
4. Generate, check the rendered text for typos, and post it today.

Pro tips

• Get permission and keep it real. Use the client’s actual words and a real name or initial. Never invent a testimonial.
• Trim the quote to one breath. The strongest cards hold one or two short sentences. If the review is a paragraph, pull the single most concrete line.
• Build a template, not one-offs. Once a layout works, reuse the same brief and swap only the quote and name so your whole feed stays consistent.
• Expect text-rendering misses. Most image tools still fumble longer text. Generate the styled background, then add the words yourself for crisp type, using the option (c) note.
