Readable text in AI images: slides, infographics and logos

Words are the hardest thing for an image model: an extra letter, an invented word, a label nobody asked for. Infographics & Data, Business & Marketing and Design & Branding in Prompt Gallery are full of text, and their prompts are written to keep it right. This lesson explains how, so you can change the words safely.

#Read the text rule

Open Pitch Deck Title Slide from the pitch deck kit. Near the end of the prompt is a text rule:

Text: the only words in the image are exactly "[Your Brand]", "Investor
Presentation 2026". Spell every word exactly as written, in a clean [heading font]
typeface, large enough to read on a phone. No other words, letters or numbers,
no placeholder text, no watermark.

Four things make it work:

1. It lists every word that should appear, in quotes
2. It says these are the only words, so the model does not add its own labels
3. It asks for exact spelling
4. It asks for text large enough to read, because small text is where letters go wrong

The negative prompt backs it up: misspelled words, gibberish text, extra labels, lorem ipsum, tiny unreadable text.

#Change the words without breaking the rule

When you change what the image says, change it in both places: where the text is described in the scene, and in the quoted list of the text rule. If the scene says "a subtitle" but the rule does not list it, the model may leave it out or make one up.

Keep the text short. Two to six words per text element is reliable; a paragraph is not. Put long text on the slide yourself afterwards, and let the image carry the picture and a headline.

#Pick the right model for text

Each open prompt lists the models it was written for under Written for, and you can search by model name. Every prompt in Infographics & Data is written for Ideogram, GPT Image, Nano Banana and Imagen, four models known for handling text, and so are most of the slides, posts and print in Business & Marketing. Search ideogram or gpt image to see every prompt written for one of them.

Models change quickly. If a model spells badly, try the same prompt in another one before you rewrite it.

#Build an infographic step by step

Infographics & Data is organised by the shape of the information: Process & Steps, Timelines & Roadmaps, Charts & Stats, Comparisons, Diagrams & Frameworks and Explainers & Guides. Pick the tab that matches your content, not the prettiest picture.

Then:

1. Count your items. A prompt for four steps will not draw six well; find one with the right number or change the number in every place it appears
2. Replace the labels in the text rule with yours, short and exact
3. Keep the numbers you want shown as plain as possible: 42%, not approximately 42.3 percent

#Check every word

Before you use an image with text, read it letter by letter, at full size. If one word is wrong, regenerate; small fixes are often easier in an image editor than in a new prompt.

The next lesson takes any gallery prompt to your image tool of choice: Midjourney, Flux, Nano Banana and others.
