Image generators are AI tools that use artificial intelligence to turn text into images. These tools employ deep learning algorithms to examine the relationship between text and images, and then use this understanding to create new images based on the given text.

The results of these algorithms continually improve with each version, producing high-quality depictions of real photographs and artwork crafted by humans.

In 2022, several image generators were launched, including OpenAI's DALL-E 2, Leonardo.Ai, Stable Diffusion by StabilityAI, Google's Imagen, Midjourney, to name a few.

Now, let's delve into a closer look at some of these tools.


An AI image generator developed by OpenAI. DALL-E can generate lifelike images from plain text. For example, if you enter the phrase "dog walking in the grass," DALL-E creates an image of a dog in the grass. Trained on millions of images and sentences, it recognizes key features like shapes, colors, and object relationships. The tool can be used for numerous applications, such as graphic design, marketing, education, research, and more. Although still in its early stages, it has the potential to revolutionize the creative and design industry with its ability to leverage diverse data and complex models. The tool is part of the ChatGPT Plus package, offering free access to subscribers.

  • Technology: Uses a generative pre-trained transformer model.

  • Advantages: Fast, user-friendly, included in ChatGPT Plus, providing added value for the subscription fee.

  • Disadvantages: No free trial; without ChatGPT Plus, usage can be relatively expensive.


An AI image generator developed by Google. Introduced during Google I/O 2023 conference, Imagen shares similarities with DALL-E, but employs a different technology. Developers claim it can produce more realistic images than DALL-E due to diffusion models excelling in intricate details and diverse textures.

  • Technology: Uses the diffusion model, a deep learning model that generates a random image and refines it until it meets defined criteria.

  • Advantages:

    - Realism - Imagen creates highly realistic images with intricate details.

    - Creativity - Imagen produces diverse and creative images, thanks to advanced deep-learning algorithms.

  • Disadvantages:

    - Processing Time - Imagen, being a complex tool, requires significant processing time.

    - Accuracy - It may generate unrealistic or incorrect images.

    - Misuse - Imagen may create fabricated or misleading images. While promising, caution is necessary, especially in advertisements.


This free AI-based image generator by Leonardo.Ai is widely acknowledged and respected today. Serving as an online platform, it employs the Stable Diffusion model and other custom models for creating images in various styles.

  • Technology: Utilizes the Stable Diffusion model, an open-source machine learning model.

  • Advantages:

    - Offers a diverse array of models for creating images in different styles.

    - Features a real-time canvas editor that generates images while drawing basic lines.

    - Provides an extensive sample library with user images and instructions.

    - Includes personal training and datasets, allowing users to craft images in a user-defined style.

    - Capable of producing a variety of textures.

    - User-friendly and convenient application.

    - Facilitates the upload of image collections, streamlining custom model training. The algorithm adapts to the user's style, enabling the creation of images in the same style. Additionally, images from other users can serve as inspiration or a guide for accurate instructions, stored in the platform library.

    - Leonardo's free plan is available, presenting an excellent solution with 150 images per day. Payment versions extend up to 60,000 images per month.

  • Disadvantages:

    - In comparison to other tools, Leonardo.Ai requires a significant investment in learning to master all settings and experiment with models.

    - Offers limited customer support.


A tool that converts text into images using natural language processing, Midjourney has gained popularity thanks to its capability to generate high-quality images based on textual input. The tool functions through a subscription-based service, providing users access to its image creation capabilities. The Midjourney team has actively improved the tool, recently launching Midjourney V5 with updates for responsiveness, image quality, and realism. Users can engage with the Midjourney Bot on the Midjourney Discord server to create images based on their instructions.

  • Technology: Utilizing a non-open source machine learning model, differing from Stable Diffusion.

  • Advantages:

    - Lauded for its high-quality image creation, catering to users without artistic skills.

    - Features a user-friendly interface that swiftly translates text prompts into images, facilitating the exploration of new ideas.

    - Prioritizes aesthetic coziness, considering complementary colors and proportions for visually appealing images.

  • Disadvantages:

    - Limited customer support raises concerns about assistance and issue resolution.

    - All photos created with Midjourney are public, potentially posing privacy concerns.

    - Reported issues with sign-up and a lack of a free trial may present accessibility challenges.

In summary, Midjourney offers high-quality image creation, user-friendly operation, and a focus on aesthetic appeal. However, it may encounter limitations regarding customer support, image privacy, and accessibility.

A free tool that streamlines image creation without the need for sign-up.

  • Advantages:

    - Unlike most image creation services that generate only 4 images per prompt, requiring retries and extending the character and concept creation process, is faster. It generates images in real-time as you scroll, enhancing the effectiveness and smoothness of the experience. With PicFinder, you can scroll endlessly between images for each prompt, eliminating the wait for 4 images at a time. Additionally, you can click on a result and scroll through variations of it or modify the prompt using the result as the source. You also have the option to display images based on a sample image that serves as the foundation.

    - The tool excels in high-quality image creation, leveraging extensive training on vast amounts of image data to ensure top-notch results.

  • Disadvantages:

    - Limited editing options and features.

    - Guidelines are quite similar and may display some previously created images. is praised for its user-friendly approach to producing high-quality images with flexibility in customizing image size, all for free. However, it's important to note its limitations in terms of options and editing features. Overall, it stands out as a valuable tool for creating a diverse range of images, though users should be aware of its relatively limited editing capabilities.
