The prompt

Paste this into ChatGPT with image creation on. Change the subject and the three lines of words for your own, and check the spelling before you send it.

Create a finished graphic design: a poster in A3 portrait (1:1.41) format. It is for: Evening coding bootcamp open house.
It must look designed and made by hand by a skilled human designer and illustrator, in the style described below. Treat the style as a strict art direction.

STYLE: Keycap Type

Signature moves to keep:
- keys tilted in isometric rows
- one letter per key
- tiny rotated margin captions
- white panel inside black frame
- thin black outlines

SUBJECT
Show Evening coding bootcamp open house in this style. Make the subject the hero and fit everything to it: props, setting and details should belong to this subject, not to the example the style came from.

COMPOSITION
Keys cluster on a diagonal in the middle of the white panel, each carrying one letter or word, with tiny mono captions along the edges rotated ninety degrees. The black outer frame gives the poster a presentation look.

TYPOGRAPHY
The keys carry sans capitals; surrounding captions are small mono text, rotated in margins and arrows.
Render exactly these words, spelled exactly as written, and no other text anywhere:
- headline: "Learn To Code"
- second line: "Free intro class, no experience needed"
- small details: "Thu 13 Feb, 18:00, Skolgatan 5, Umeå"
Give them a clear hierarchy: the headline large and dominant, the rest much smaller.

COLOUR
Palette: #FFFFFF, #3B82F0, #F5381C, #18C23C, #F5CC1A, #E8E0CC. Primary coloured keys on white inside a black outer frame. For a brand, use the brand colour for the key tops and neutral cream for others.

TEXTURE AND FINISH
Matte plastic, soft occlusion shadows, thin outline, crisp edges.

AVOID
- glossy chrome
- lens flare
- random symbols as letters
- dark moody scene
- gibberish text
- cluttered desk props
- anything that looks AI generated: plastic sheen, airbrushed skin, overly smooth gradients, glow and lens flare, HDR, stock photo smiles
- gibberish letters, made up words or any text other than the exact words given
- watermarks, signatures, UI elements, borders or frames around the design
- filler decoration: sparkles, floating dots and stars, confetti, random geometric shapes, gradient orbs, ornamental dividers
- uniform line weight, plastic or airbrushed shading, soft storybook gloss, perfect symmetry, melted or merging details, impossible objects
- showing the design as a mockup (a poster on a wall, a phone, a hand holding it): the artwork itself must fill the whole canvas edge to edge, flat and straight on

Do not search the web or look anything up: work only from this brief, so nothing from elsewhere leaks into the design.
Make the image now, in A3 portrait (1:1.41) format, without asking questions first.

Questions

Can ChatGPT make a real keycap typography print?

It makes an image that imitates the look. For a physical version, use the image as artwork and take a print file to a printer that can reproduce the medium: a clean 3d illustration of rounded keycaps in primary colours, arranged in isometric rows, each with a letter printed in black, with thin black outlines and soft matte plastic shading.

What size should I ask for?

This style is set up for poster (A3 portrait), Instagram post (4:5), story (9:16), square post, slide (16:9). Name the format in the prompt, as the examples do, and the layout follows it.

Why do the words come out wrong?

Image models draw letters as pictures, and they sometimes get them wrong. Keep the words short, put them in quotes, and check every letter. In OpenTempl you can leave room for the words and add them as live text.
