You finally scheduled the webinar. Then you hit the registration page builder and there’s a big empty banner staring back at you. A bare or off-brand cover quietly tells visitors the event isn’t a big deal, and your sign-up rate pays for it.
This prompt fixes that without making you learn design. It is a meta-prompt: you describe your webinar and brand in plain words, and it writes the webinar graphics for coaches prompts you paste straight into Midjourney, DALL-E, or Gemini, plus a Canva layout for the text. Below you’ll see the complete prompts and Canva plan it produces before you ever run it.
When to use this
- You’re building a registration or landing page and need a header that looks designed.
- You’re promoting a free masterclass but want it to feel premium and worth the hour.
- You need matching social and email images that all share one cover look.
- You use Midjourney or DALL-E but your event covers come out cluttered or off-brand.
The prompt
Copy this whole block into ChatGPT, Claude, or Gemini:
You are an expert art director and prompt engineer for AI image tools, specializing in event and webinar marketing. Your job is to write me ready-to-paste image prompts for a webinar/masterclass cover graphic that makes people stop and register. I am a coach, not a designer, so do the creative thinking for me.
Before writing, ask me up to 3 clarifying questions if anything below is unclear or missing. Otherwise, proceed.
CONTEXT
- Webinar/masterclass title: {{WEBINAR_TITLE}}
- My niche: {{NICHE}}
- Who should register (ideal attendee): {{IDEAL_ATTENDEE}}
- My brand mood/aesthetic: {{BRAND_MOOD}}
- My brand colors: {{BRAND_COLORS}}
- Where the cover will live: {{PLATFORM}}
- The image tool I use: {{IMAGE_TOOL}}
TASK
1. In one sentence, describe the cover concept so I understand the visual idea and why it fits my attendee.
2. Write 3 distinct, ready-to-paste prompts for {{IMAGE_TOOL}}, each a different creative direction but all matching {{BRAND_MOOD}} and {{BRAND_COLORS}}.
3. For each prompt specify: subject/scene, composition (leave clean negative space for the title and date), lighting, color palette, style/medium, mood, and the correct aspect ratio for {{PLATFORM}}.
4. Include the correct syntax for {{IMAGE_TOOL}} (e.g. --ar for Midjourney; plain descriptive language for DALL-E/Gemini).
CONSTRAINTS
- Design for a clear focal point with empty space where the webinar title, date, and a call-to-action button will be added later.
- Avoid clutter, text artifacts, and stocky cliches (no fake-smiling handshake photos, no generic lightbulbs).
- Do not try to render the webinar title inside the image; image AIs mangle text. Recommend adding all text in Canva afterward.
- Keep the look on-brand and premium so the page signals a paid-quality event even if it is free.
Then give me a ready-to-use Canva text layout suggestion (where to place the title, date, and CTA button) and 5 reusable style keywords I can append to future event prompts to keep my brand look consistent.
How to customize it
Replace the seven {{VARIABLES}} before you send it:
| Variable | What to put | Example |
|---|---|---|
{{WEBINAR_TITLE}} |
Your event title | The Fully-Booked Coach: 3 Steps to a Waitlist |
{{NICHE}} |
Your coaching niche | business coaching for service-based founders |
{{IDEAL_ATTENDEE}} |
Who should register | coaches stuck under 10 clients who rely on referrals |
{{BRAND_MOOD}} |
Your aesthetic | confident, modern, warm but premium |
{{BRAND_COLORS}} |
Your brand colors | deep navy, warm gold, off-white |
{{PLATFORM}} |
Where it lives + size | a Kajabi registration page header, 1200×628 |
{{IMAGE_TOOL}} |
Your image AI | Midjourney |

Here is the exact prompt, filled in for a business coach running a free masterclass. This is the whole input, nothing hidden:
You are an expert art director and prompt engineer for AI image tools, specializing in event and webinar marketing. Your job is to write me ready-to-paste image prompts for a webinar/masterclass cover graphic that makes people stop and register. I am a coach, not a designer, so do the creative thinking for me.
Before writing, ask me up to 3 clarifying questions if anything below is unclear or missing. Otherwise, proceed.
CONTEXT
- Webinar/masterclass title: The Fully-Booked Coach: 3 Steps to a Waitlist
- My niche: business coaching for service-based founders
- Who should register (ideal attendee): coaches stuck under 10 clients who rely on referrals
- My brand mood/aesthetic: confident, modern, warm but premium
- My brand colors: deep navy, warm gold, off-white
- Where the cover will live: a Kajabi registration page header, 1200x628
- The image tool I use: Midjourney
TASK
1. In one sentence, describe the cover concept so I understand the visual idea and why it fits my attendee.
2. Write 3 distinct, ready-to-paste prompts for Midjourney... [rest of the prompt unchanged]
And here is the complete output the model returns:
Quick check before I write these:
- Will your headshot appear on the cover, or do you want it image-only with no people?
- Is the masterclass live or pre-recorded (changes whether I suggest a “LIVE” badge in the Canva layout)?
- Landscape 1200×628 confirmed for the Kajabi header, yes?
Assuming image-only, live, and 1200×628 (16:9-ish landscape), here’s what I’d build:
Concept: a calm, premium desk-and-light scene that signals “a real strategy session, not hype,” with a clean open left side where your title and CTA button sit, so the design does the credibility work and the text does the selling.
Prompt 1 (premium desk scene):
modern minimalist coaching workspace, a clean desk with an open notebook, a warm cup of coffee and a laptop slightly out of focus, deep navy and off-white palette with subtle warm gold accents, soft morning window light from the right, generous empty space on the left third for text, confident premium editorial style, shallow depth of field, calm and aspirational mood --ar 16:9 --style rawPrompt 2 (abstract brand gradient):
elegant abstract background, deep navy flowing into off-white with delicate warm gold light streaks, subtle soft grain texture, gentle directional glow from the upper right, ultra-minimal and premium, large clean negative space across the center for a headline, modern fine-art print style, confident and modern mood --ar 16:9Prompt 3 (upward-momentum motif):
minimalist conceptual image of a single rising line of warm gold light gently ascending across a deep navy field, off-white soft glow, restrained and sophisticated, no text, plenty of open space on the left for a title, premium editorial poster style, optimistic and grounded mood --ar 16:9Canva text layout suggestion (1200×628): – Left third, top: small all-caps eyebrow in warm gold, “FREE LIVE MASTERCLASS”. – Left third, center: the title “The Fully-Booked Coach: 3 Steps to a Waitlist” in a bold off-white serif or strong sans, 2-3 lines, left-aligned. – Below the title: date and time in a lighter off-white weight, e.g. “Thursday, June 12 · 12pm ET”. – Bottom-left: a solid warm-gold CTA button with navy text, “Save My Seat”. – Optional top-right corner: a small “LIVE” badge so it reads as a real-time event.
5 reusable style keywords (append to any future event prompt):
deep navy and warm gold palette,premium editorial style,soft directional light,generous negative space for text,confident and modern mood
That’s a registration header you can have live in fifteen minutes: generate one of the three in Midjourney, drop it into Canva, and lay the text exactly where it told you to.
Why this works
Three LLM principles are doing the heavy lifting here. Learn them and every prompt you write gets sharper:
- Role priming. The opening line casts the model as “an expert art director and prompt engineer… specializing in event and webinar marketing.” That tells it which slice of its knowledge to draw from. “Make me a webinar image” pulls the bland average of the internet; naming a specialist role pulls art-direction language like composition, negative space, and aspect ratio. Always assign a role.
- Specificity in, specificity out, plus clarifying questions. The model can only be as specific as your input, so the prompt feeds it your title, attendee, mood, colors, and exact platform size. The “ask me up to 3 clarifying questions first” line is the safety net: instead of guessing whether your face is on the cover or whether the event is live, it asks. That single instruction is the biggest fix for generic AI output, because it lets the model fill gaps with your truth rather than its assumptions.
- Constraints are quality control. The “do NOT render the title inside the image,” “no stocky cliches,” and “leave negative space for text” lines each remove a known failure mode. Image AIs mangle text and love clutter; telling the model what to avoid, and routing the text job to Canva, plays each tool to its strength. Telling the model what NOT to do is as powerful as telling it what to do.
Do this now

- Replace the seven variables with your real title, niche, attendee, mood, colors, platform size, and image tool.
- Send it. If it asks clarifying questions, answer them honestly, then let it write the prompts.
- Generate one image, drop it into Canva, and add your title and CTA using the layout it gave you. Publish the page today.
Pro tips
- Always pass the exact pixel size. “1200×628” or “16:9” tells the model the right aspect ratio so your cover isn’t cropped awkwardly on the page.
- Generate the background empty, add text in Canva. Image AIs still mangle words; render clean negative space here and lay the title on top for crisp, readable type.
- Reuse the 5 style keywords. Append the same look-defining words to every future event cover so your webinars, emails, and social promos all match.
- Make a matching set. Ask it to resize the winning concept to a 1080×1080 social square and a 1080×1920 story so your whole promo campaign shares one look.
