Cover designer: how to compose an exact prompt for a vector cover
"Cover designer" is a web tool for creating vector covers with a readable title and thoughtful composition. To make the result match the task, it is important to formulate the request accurately. In this article we will look at what data to enter in the fields, how to avoid typical errors and what to pay attention to when checking. We will not delve into general AI reasoning, but focus on the practical use of the tool.
Open tool: Cover designer ↗What is "Cover designer" and what tasks it solves
"Cover designer" is a web tool that creates a vector cover based on your textual description. You fill in three fields: "Your text or idea", "Style, style or format" and "Output format". The tool generates one result in a separate panel, which can be copied or downloaded as SVG or PNG. It is important to understand that this is exactly vector graphics, not a photorealistic image. The tool does not support export to DOCX or PDF, does not perform batch processing and does not save results automatically.
The main task is to help you quickly get a cover layout that can be used as a basis for further work. For example, for a book, brochure, presentation or podcast cover. The tool does not guarantee that the final design will be perfect right away, but it gives a starting point that can be refined in a vector editor.
It is important to consider the limitations: the maximum length of the first field is 8000 characters, the second - 1000 characters. The output format is selected from available ones (SVG, PNG). The tool does not generate audio or video, does not clone voice and does not create photorealistic images. All these limitations are important to consider when formulating the task.
Bad prompt: "Make a beautiful cover". Good prompt: "Cover for a book about houseplants, title "Green Balcony", style - minimalism, format - SVG".
Field "Your text or idea": what to write to get the desired result
This field is the basis of the task. Here you describe what should be on the cover: title, subtitle, key elements, color palette, mood. The more specific the description, the closer the result. For example, if you want a cover for a cookbook, indicate the title, author, genre and preferred colors. If it is a cover for a report, describe the topic, key numbers or graphs that should be reflected.
Avoid general phrases like "make it beautiful" or "something modern". The tool cannot read minds. Instead, list specific elements: "Title: "Urban Gardens". Subtitle: "Practical guide". Colors: green, white, gray. Style: clean, geometric. Place the title at the top, subtitle at the bottom." You can also specify what images or icons to use: "plant silhouette", "abstract lines".
Remember, the tool creates a vector composition, not a photograph. Therefore descriptions like "photorealistic sunset" will not work. Better to use vector graphics terms: "flat shapes", "gradient", "contour lines". If you are not sure about the terms, describe in simple but specific words: "background of geometric shapes", "large sans-serif font".
Bad: "Cover for a book". Good: "Cover for book "Green Balcony" about growing plants on a balcony. Author: Anna Petrova. Style: minimalism, lots of white space. Colors: green, white. Title in large font in center, author - small at bottom. Add simple vector drawing of a plant pot".
Field "Style, style or format": how to set the visual direction
The second field allows you to specify the style: minimalism, retro, futurism, handwritten, strict, playful. You can also specify the tone: official, friendly, mysterious. This affects the choice of fonts, colors and composition. For example, for a business report a strict style with blue and gray tones is suitable, and for a children's book - bright and playful.
If you do not specify the style, the tool will choose something by default, which may not match your expectations. Therefore it is better to explicitly specify: "style: minimalism, sans-serif font, cold colors" or "style: retro, warm shades, vintage elements". The field limit is 1000 characters, which is enough for a detailed description.
You can also indicate the output format in this field, but usually there is a separate field for that. Do not duplicate information unnecessarily. If you want the cover to be in landscape orientation, specify it in the format field or in the description.
Bad: "Stylish". Good: "Style: minimalism, Montserrat font, color palette: green, white, light gray. Tone: calm, professional".
Output format field: choosing between SVG and PNG
The tool supports two vector formats: SVG and PNG. SVG is scalable vector graphics that can be edited in Illustrator, Inkscape or Figma. PNG is a raster format, but in this case it is also created from a vector composition, so it retains clarity at sufficient resolution. Choose SVG if you plan to edit the design, and PNG if you need a ready-made image for insertion into a document or presentation.
In the "Output format" field you usually need to choose one of the options. Do not specify other formats here, such as PDF or DOCX - they are not supported. Also remember that the tool does not perform batch processing: one request - one result. If you need several variants, you have to generate them one by one.
If you are not sure which format to choose, start with SVG. It can always be exported to PNG later. Moreover, SVG allows easy color or font changes without loss of quality.
In the "Output format" field choose SVG if you want to edit the cover later in a vector editor. Choose PNG if you need a ready-made image for a blog post.
Example of bad and good prompt: comparison
A bad prompt is often too general: "Make a cover for a book". The tool does not know the topic, title or style. In the best case it will generate an abstract composition that is unlikely to fit. A good prompt contains specificity: "Cover for book "Green Balcony" about growing plants on a balcony. Author: Anna Petrova. Style: minimalism, lots of white space. Colors: green, white. Title in large font in center, author - small at bottom. Add simple vector drawing of a plant pot. Format: SVG".
The difference is obvious: in the second case the tool gets clear instructions on content, style and composition. This increases the chances of a satisfactory result. However, even a good prompt does not guarantee an ideal result - the tool may make mistakes, and the result will have to be refined.
Another example: for a podcast cover about technology you can write: "Cover for podcast "Technologies of the Future". Title large, subtitle "Trend review". Style: futurism, dark background, neon accents. Format: PNG". This prompt contains all necessary elements.
Bad: "Cover for a book". Good: "Cover for book "Green Balcony" about growing plants on a balcony. Author: Anna Petrova. Style: minimalism, lots of white space. Colors: green, white. Title in large font in center, author - small at bottom. Add simple vector drawing of a plant pot. Format: SVG".
How to check the result and consider limitations
After generation carefully examine the obtained cover. Check the readability of the title: is it overlapped by other elements, is the font size sufficient. Make sure the composition is balanced and matches the selected format. If something is not right, try to change the task: clarify style, colors, element placement. The tool does not guarantee an ideal result right away, but iterations help improve it.
Remember the limitations: the tool does not support export to DOCX or PDF, does not perform batch processing, does not automatically save results. The maximum length of the first field is 8000 characters, the second - 1000. If you exceed the limit, the task will not be accepted. Also the tool does not generate photorealistic images and does not create audio or video. All this is vector graphics.
If the result contains errors (for example, unreadable text or strange composition), do not despair. Try to rephrase the task, break it into parts or simplify it. Sometimes adding specific details helps: "use sans-serif font", "place text on the left", "add geometric pattern". Experiment, but within the tool's capabilities.
After generation you see that the title is too small. Add to the task: "Title must take at least 30% of the cover height". This specific requirement will help the tool.
Practical tips for formulating the task
Try to write the task so that it can be understood by a person unfamiliar with your project. Avoid pronouns and references to context known only to you. For example, instead of "make it like last time" write "style: minimalism, colors: blue and white". The more autonomous the description, the better.
Use a structured approach: first indicate the goal (book, podcast, report), then title and subtitle, then style and color palette, then special composition wishes. Such order helps not to miss important details. If you are limited in characters, shorten, but not at the expense of specificity.
Do not be afraid to experiment with formulations. If one variant did not work, try another. For example, if the tool does not understand "futurism", replace it with "dark background, neon lines, geometric shapes". The main thing - maintain specificity and avoid general phrases.
Instead of "make it modern" write "use flat icons, sans-serif font, gradient from blue to purple".
"Cover designer" is a useful tool for quickly creating vector covers, but its effectiveness depends on the quality of the task. Clearly describe content, style and format, avoid general phrases, consider limitations. Check the result and if necessary correct the task. Remember that the tool does not guarantee an ideal result, but with the right approach you can get a good basis for further work. Experiment and do not be afraid to clarify details - this is the key to success.
