Users generate images from text prompts or optionally upload reference images for use with trained models. The platform offers multiple featured model options with different aesthetic styles, as well as the ability to train custom models on uploaded reference datasets. A real-time generation mode produces images as the user types, enabling rapid visual exploration. The AI Canvas allows image editing, outpainting, and compositing within the browser. Generated images can be downloaded or shared.
Leonardo AI
Leonardo AI is a creative AI platform focused on image generation, with a particular emphasis on game assets, character design, and consistent visual style. It is distinct from general image generators in that it provides tools for training fine-tuned models on user-uploaded reference images, enabling consistent character and object appearance across generated outputs.
The platform is used by game developers, artists, and creative teams who require visual consistency across a body of work — a challenge with prompt-only image generators where characters and styles can drift between generations.
Leonardo AI offers real-time generation and canvas editing features alongside its standard generation workflow, making it a more complete creative tool than simple text-to-image platforms.

Pros & Cons
Pros
- Custom model training enables consistent character appearance
- Game-specific presets produce relevant art styles
- Real-time generation accelerates visual exploration
- Relatively generous free credit model
- API access for programmatic integration
Cons
- Custom model training has a learning curve
- Total credit system can be confusing
- Advanced capabilities require paid subscription or credits
- Less strong for photorealistic versus stylised outputs
- Community features can make the interface feel cluttered
Pricing
Leonardo AI offers a free plan with a daily token allocation for image generation. Paid plans increase monthly token allocation, priority access to featured models, and commercial usage rights. Custom model training, higher resolution generation, and API access are available on higher tiers. Plans are billed monthly or annually.
How It Compares
Leonardo AI competes with Midjourney, Stable Diffusion, and Adobe Firefly in the image generation space. Midjourney produces more artistically polished output but offers no fine-tuning. Stable Diffusion matches Leonardo in fine-tuning capability but requires self-setup. Adobe Firefly targets professional commercial workflows with Creative Cloud integration. Leonardo differentiates on being accessible via web browser with built-in custom model training — a combination not offered by most alternatives.
