What is an AI image generator?

An AI image generator from text is exactly what you think it is. It is an AI-powered tool that takes a text prompt, processes it, and creates an image that best matches the description given in the text prompt. Don’t confuse them with AI image-sourcing tools though. AI image generation is completely different from sourcing. While image-sourcing tools can be used to search and download existing images available on different platforms, an AI image generator creates entirely new images that do not exist in reality.

Narrato is an AI Content Workspace that offers both these capabilities. The AI Images tool allows you to create your own customized AI images with just a few words.

There is also the Free Image Search tool, which allows you to search for attribution-free stock images (sourced from Unsplash, Pexels, Pixabay, and Canva) to go with your content.

The idea of generating images from text using AI has been around for several decades. But the recent advancements in the field of text-to-image generation have made it possible to develop more sophisticated tools that are able to create high-quality images with different art styles. This has opened up a world of possibilities for anyone working with visual content. Your prompt could be anything, like “an apple-shaped chair in a sunlit lounge with a teddy bear sitting on it” to “a donkey in a spacesuit”. Take a look at these two AI photos created using Narrato’s AI image generator.

With an AI picture generator, you can dream up whatever you’d like and bring it to life! Create images of animals, landscapes, characters, objects, 3D models, and more, and customize and personalize them with various details. You can truly let your creativity run free since the only real limit is your imagination.

How do AI image generators work?

An AI image generator uses an advanced machine learning algorithm known as artificial neural networks (ANN) to generate new images. The ANN, which is modeled on biological neural networks, is trained on a large number of image-text pairs. It processes this information to learn everything, whether it’s Van Gogh’s paintings, the blue color, or what different objects look like. After learning the patterns and styles from the existing data, the AI image generator can interpret every text prompt to create new images mimicking any art form. And it does so in a matter of seconds. This means that the user can see the resulting AI image almost immediately.

Using AI image generators in content marketing

The world of content marketing, as it exists today, is radically different from what it was a few years ago. It’s not so much about quantity anymore, as it is about quality. And while content SEO and traffic generation are still important, the focus has shifted toward creating content that engages the audience and truly resonates with them.

If the content space is like a battle arena, only the most creative brands will come out on top. So, businesses have realized the need to employ new techniques for content creation, marketing, and content distribution. While large enterprises often have a dedicated content team, along with content strategists, writers, editors, and visual designers, small and medium businesses without a large content team remain at a disadvantage. In this case, the outcome of the battle might seem predictable. Except that it isn’t. SMBs now have a buddy they can turn to for assistance — AI tools.

Artificial Intelligence (AI) tools have revolutionized the world of content marketing by streamlining the content workflow and automating several processes. If you’re having trouble coming up with creative content topics, you can turn to AI topic generators. If you need a writing assistant to help you with creative blocks, there is the AI writer. If you’re looking to optimize your content for SEO, you can create complete content briefs using an AI SEO content brief generator. And latest entrant among these AI tools is the AI image generator. With an AI image generator in your content creation tool stack, adding visual elements to your blogs, social media content, and other marketing content becomes a breeze.

We’ve talked a lot about AI image generators until now, and we’re sure you must be curious to learn the practical applications of these tools. The upcoming sections will cover the art of creating AI created images in greater detail.

How can content marketers use AI image generators like Narrato?

Crafting engaging visual content is no easy task; it requires careful thought, attention to detail, besides some level of creative skills. A recent Venngage survey has found that the biggest challenge for 31.8% of marketers while creating visual content is producing it consistently. Coming up with great designs every time was also a major challenge for 19.6% of surveyed marketers.

Coming up with original images and graphics is not possible every time, and you can depend only so much on stock photos. AI-generated images can come to your rescue here. By using Narrato’s AI image generator as your creative sidekick, you can improve the efficiency of your visual content development process. This text-to-image generator essentially allows you to create 4 artificial intelligence pictures with a single prompt. And these are not just generic-style images. Narrato’s AI image generator gives you the option to choose the style of image, with options like -

There are also additional style options like -

You can access the AI Images tool through the AI Content Assistant on the Narrato Workspace. It’s also available on the content task page, for ease of creating images while writing content. Using this tool is fairly simple. All you have to do is provide the tool with a prompt describing the image with as many details as you want. You can add up to 1000 characters in the image description. After adding the prompt, just select the style of the image from the options available, and click generate. Et voila! Your AI image will be ready.

If the results don’t quite meet your expectations, don’t worry — you can always go back and give it another go. Try switching up the words or adding more detail to really get the image you’re looking for. Experiment with different combinations of text, prompts, and styles until you’re satisfied with the outcome. The custom AI image generated can then be added to your blog posts, website copy, social media content, or, anywhere else.

With the basics of AI image generators covered, let’s take a look at some tips for creating stellar AI-generated photos.

Using AI Image Generators: Tips and Best Practices

Creating truly remarkable AI images requires more than just plugging random words into the AI image generator and hoping for the best. If you want to create something truly special, here are some tips for using AI image generators -

1. Develop a general idea for the AI image

Before you can start experimenting with image description prompts, you need to have a general idea about the kind of AI image you’d like the tool to create. Decide on the subject matter for the image. What is the general feeling you want to evoke through it? What would the scene be like? Would there be any other objects in the frame? This will form the foundation of the AI image generation process.

Here’s an excellent tip — A reverse image search using Pinterest or Google Images can help you develop a better understanding of what you should include. Examine the tags associated with the images to narrow down some words you can use for the prompt.

2. Learn the nitty-gritty of prompt engineering

The accuracy and quality of the AI-generated images depends a lot on how well you’re able to craft the image description prompt. If you know some basics of prompt engineering, creating stellar AI images will become easier. Here are some tips for writing a good prompt -

  • Make sure your description contains a noun, a verb, and an adjective.
  • Don’t limit yourself to one adjective. Using multiple adjectives will help create an AI image that accurately represents the intended concept.
  • To provide better context, use at least 3 words. The upper limit depends on your tool. With Narrato’s AI image generator, you can add a maximum of 1000 characters.
  • If you want the AI image to mimic the style of any popular artwork or cartoon, use “in the style of” in the prompt. Here is an example, where we asked the tool to create “a picture of a sunset in the style of The Simpsons”
  • If you are looking to create artwork in a specific style, try to include the names of different art styles (contemporary, surrealism, minimalism, etc.) in the prompt.
  • Mention the quality your want — high/medium/low/4k/8k. Here, we first asked the tool to generate a low-quality image of a sunset, and then a high-quality image of a sunset. You can clearly see the difference between the two.
  • Specify the color palette for the image in your prompt. Prompt example: “Create an image of a work desk using the color palette yellow”. Here is the result –

3. Learn graphic design, photography, art jargon

The key to creating better AI images is using the right words. And the best way to describe images can be found in the jargon used in graphic design, photography, and art. It’s a good idea to learn the specific terms used in these fields to provide a more accurate prompt to your AI image generator.

  • Photography jargon keywords: Bokeh, exposure, white balance, contrast, saturation, vibrance, hue, tonal range, sharpness, grain/noise, vignetting, etc.
  • Graphic design jargon keywords: Kerning, symmetry, asymmetry, texture, layout, white space, balance, proportion, etc.
  • Art jargon keywords: Surrealism, Impressionism, Minimalism, Brushstroke, Impasto, Avant-garde, and more.

Pro Tip: If you want the AI art to mimic the work of an artist, you can include their name in the prompt. You can also include the name of multiple artists to merge the style of their artworks.

Here, we provided the prompt — “girl watching the sunrise on the beach, in the style of Van Gogh and Vermeer”. This is what it came up with -

4. Repeat your prompt multiple times

When the same prompt is repeated to AI image generators, they are able to learn the associated concepts more accurately. So, if you’re not happy with the results on your first try, try again, and again and again. With repeated prompts, the AI image generator will be able to better understand what you want, especially if it’s an abstract concept.

Pro tip: While repeating the prompt in multiple AI image generation efforts will give better results, you can also achieve this by repeating certain words in the prompt. For instance, “a very very very beautiful night sky”.

5. Experiment with the AI image generator settings

Artificial Intelligence image generators provide a range of settings to customize the output. It is recommended to experiment with these settings to get the desired outcome. Tinkering with the settings will allow you to tailor the AI image output to better suit your needs. You can adjust parameters such as color, resolution, contrast, etc., in the prompt, and choose different styles to create AI images. Try different combinations to get the perfect image output for your content piece.

6. Refine the images with post-processing tools

After you’ve generated the AI images with an AI image generator, you can use post-processing tools like Adobe Photoshop, Luminar, and GIMP to enhance the quality of the images. Post-processing tools can help you fine-tune the AI images so that they look exactly the way you want them to. You can use these tools to adjust the colors, brightness, contrast, and other aspects of an AI image.

Benefits of using AI image generators

AI image generators offer numerous benefits to content creators, marketers and other creatives. With just a few clicks, you can produce images that appear to have been taken by an expert photographer. You can even create images of things that would never be found in reality.

Here’s everything you can get from using AI image generators -

  • Higher productivity: You can create beautiful images and graphics without having to learn the complex art of editing. You wouldn’t have to browse through hundreds of stock photos either to find a perfect image.
  • Unique images: Every single image created by an AI image generator is one of a kind. You can be sure that your visual content will be unique.
  • Greater control over design: With an AI image generator, you’re not dependent on the existing set of design features offered by a graphic design tool. You can add as many details as you like, whether it’s adjusting the textures, lighting, color palette, or anything else.
  • High-resolution AI images: AI text-to-image generators can help your create detailed, high-quality images. With Narrato’s AI image generator, for instance, you get a standard resolution of 512×512 pixels, making it great for any content project.
