The easiest way to create an AI image is to describe the scene you want to ChatGPT or Gemini.
There's nothing to install. You type "make me an image like this," get a result, and if you don't like it, you keep the conversation going and refine it.
But look a little further into AI image generation and you'll find platforms built specifically for it, such as Leonardo AI, Ideogram, and PixAI.
So if ChatGPT can already make images, why would anyone use a dedicated service?
The short answer: it comes down to what you're making the image for and how much control you need.
Free AI Image Generators: Start by Defining Your Purpose
When choosing an AI image generation tool, there are three main criteria to consider.
1️⃣ The first is convenience.
If you just want to type a prompt and get a result with no complicated settings, conversational AI like ChatGPT and Gemini is the easiest option.
2️⃣ The second is fine-grained control over the generation process.
If you want to choose the model and style yourself and steer the output toward exactly what you have in mind, a platform built for image creation, like Leonardo AI, is worth considering.
PixAI specializes in anime, illustrations, and character art
3️⃣ The third is what the final image is for.
A poster with text, an anime-style character, or a photorealistic image that looks like a real photo: each calls for a different tool.
The Easiest Way to Start: ChatGPT and Gemini
✅ ChatGPT's biggest advantage is that you can create images through conversation alone, with no image-generation interface to learn.
Beyond generating new images, you can upload an existing image and edit it, swapping out or removing specific elements. ChatGPT Images is currently available on every plan, including the free tier, which has its own usage limit for image generation.
✅ Gemini works much the same way.
The Gemini app currently supports image generation and editing powered by Nano Banana 2. You can create an image from scratch with a prompt or apply the changes you want to an existing image.
So if your goal isn't AI image generation itself but quickly getting images for a blog post, social media, or a proposal, a general-purpose AI like these is the most convenient place to start.
What Makes Leonardo AI Different as a Dedicated Image Platform?
Leonardo AI is a creative platform built specifically for generating visual content such as images and video. The biggest difference is that you take a much more hands-on role in how the image is generated.
Where ChatGPT works more like describing a scene and then refining the result through conversation, Leonardo AI lets you shape the output using a range of models, presets, and generation settings.
That makes it especially useful if you repeatedly produce content like:
Characters and illustrations
Game art
Webtoon and comic concepts
Brand visuals
Ad creatives
Product concept images
👉 In other words, if you only need an AI image now and then, a conversational tool like ChatGPT is the simpler choice. But if image creation is a core part of your content work, it's worth comparing a platform like Leonardo AI that gives you detailed control over generation.
When Text in the Image Matters: Ideogram
Ideogram is mainly used for work where text needs to appear as part of the image.
Text is a notorious weak spot in AI image generation. Say you want a café poster that reads 'NEW YORK COFFEE CLUB,' or a promo image with 'SUMMER SALE' built into the design.
Generating a background image is one thing. Getting the letters to render cleanly as a natural design element inside the image is a different problem.
Ideogram's main selling point is image generation with strong text rendering, which makes it a good fit for posters, ad creatives, typography, and thumbnails.

Have a specific goal? Consider Canva AI, PixAI, or FLUX
👉 If your goal is to take the image all the way to a finished YouTube thumbnail or Instagram post, a service that combines design tools with AI, like Canva AI, may actually be more convenient. You can add your title on top of the generated image and adjust the fonts, colors, icons, and graphic elements yourself.
👉 On the other hand, if anime-style characters and illustrations are your main focus, a platform specialized in character art like PixAI is worth a look.
👉 If you need photorealistic people, products, or interiors, the FLUX family of models is another option. Note that FLUX isn't a single image-generation site. It's a family of image models developed by Black Forest Labs, and several services offer access to them.
You don't have to commit to a single AI image tool from the start.
For example, you could generate the image you want in Leonardo AI or FLUX, then bring it into Canva to add your copy and design elements and finish the thumbnail. Chaining tools together like this works well.
In the end, what matters in AI image generation isn't which platform is the most famous. It's deciding first what you're trying to make and what still needs to happen after the image is generated.
If you're new to AI images, start with something accessible like ChatGPT or Gemini. When you find yourself needing finer control over the results, expand into dedicated platforms like Leonardo AI and Ideogram :)
