Use Cases
Subject-specific visuals that free slides from stock-photo cliché.
Short answer
Free tools (Bing Image Creator, Google Gemini) are enough for presentation visuals. The key rule for slide imagery is that it must not compete with the text: choose simple compositions, a single subject and low saturation. When generating diagrams, add "no text" to the prompt — AI writes meaningless letters into labels; add those yourself in the presentation software.
Presentation visuals are where AI gives the fastest benefit at the lowest risk. No commercial exposure, a low quality bar, and free tools that are more than sufficient.
Even so, images in most decks do not work — because they are chosen with the wrong question. "What should I put on this slide?" leads to decorative images unrelated to the subject, stealing attention from the text.
The right question is: would this slide be incomplete without this image? If the answer is no, leave it out. If it is yes, what the image should say is already clear, and writing the prompt becomes easy.
Will the image explain a concept, set a mood, or just fill the slide? If it is the third, leave it out; an empty slide beats an irrelevant image.
Add "minimal composition, single subject, muted palette" to the prompt. Busy, saturated images make the text on a slide unreadable.
For diagrams, write "no text" in the prompt and add labels in PowerPoint or Keynote. That keeps the wording correct and means you do not regenerate the image when updating the deck.
The most common mistake with slide imagery is choosing an image that is striking on its own. In a presentation an image never stands alone; there is text over it and a speaker beside it.
A saturated, busy, high-contrast image pulls the audience's attention away from the speaker. It also makes any text placed over it unreadable.
The right image is quiet: a single subject, simple composition, low saturation, generous space. Adding "minimal composition, muted palette, generous negative space" to the prompt reliably produces that character.
Planning the empty space also makes text placement easier. An instruction like "generous negative space on the right" guarantees at generation time the area where your headline will go.
AI image models are not built to carry information. Ask for a flowchart, an org chart or an architecture diagram and you get an image that looks right and means nothing.
Boxes connect but the connections make no sense; arrows leave one place and arrive nowhere; labels are piles of unreadable letters.
The correct use is generating the diagram's VISUAL LANGUAGE, not its content. Write "no text, no labels" in the prompt to produce an empty isometric structure; take the boxes, arrows and colour scheme, then build the labels and the real structure yourself in the presentation software.
If you need an actual diagram, the right tool is a diagramming application, not an image generator. AI supplies the aesthetic layer here, not the information layer.
No. Bing Image Creator is completely free and comfortably meets the quality needed for slide imagery. Google Gemini is also free and understands Turkish prompts better. The only reason to move to a paid tool is wanting one consistent visual style across the whole deck.
It produces something that looks like one, but the content is meaningless: illogical connections, aimless arrows, unreadable labels. Image models are not built to carry information. Generate the diagram's visual language (adding "no text" to the prompt) and build the structure and labels yourself in the presentation software. For a real diagram, use a diagramming tool.
Quiet. A single subject, simple composition, low saturation and generous space reserved for text. The image should not be striking on its own; there is text over it and a speaker beside it. Adding "minimal composition, muted palette, generous negative space" to the prompt reliably produces that character.
Prompts are written in English because most tools give markedly better results with English prompts.

Note: Leaving generous space on the right lets you place slide text cleanly over the image.

Note: The phrases "no text, no labels" are mandatory; without them the diagram fills with unreadable letters.
