Leonardo.ai API Custom

What do you like best about the product?

What I like most about Leonardo.Ai is its ability to generate high-quality images with excellent creative control. It offers a good balance between ease of use and advanced features, making it suitable for both beginners and experienced creators. High-quality AI-generated images with impressive detail. Fine control over prompts, styles, and image generation settings. Support for image-to-image generation and AI editing. Fast image generation with a clean, intuitive interface. A wide variety of pre-trained models and artistic styles. For me, the most valuable feature is the level of creative control. I can experiment with different prompts, models, and styles to generate visuals for marketing materials, website assets, presentations, and creative projects without needing advanced design skills. The biggest benefit is productivity. Leonardo.AI enables me to create professional-quality visuals in minutes, reducing the time and cost involved in producing custom graphics while giving me the flexibility to iterate on ideas quickly.

What do you dislike about the product?

The biggest drawback is prompt iteration. While Leonardo.AI is capable of producing excellent images, it sometimes requires multiple attempts and prompt refinements before reaching the exact style or composition I have in mind, which can consume both time and generation credits. It often takes several prompt iterations to achieve the desired output. The credit-based usage system can feel restrictive for users who generate many images.

Instead of relying on stock images or outsourcing artwork, I can generate unique visuals in minutes. Creates custom images for marketing, presentations, and websites quickly. Reduces the time and cost of producing original graphics. Helps visualize ideas and concepts before finalizing designs. Enables rapid experimentation with different styles and creative directions.

Advanced tools, like video generation, drain credits very quickly. It also occasionally struggles with fine details, such as hands and getting text exactly right.

What do you like best about the product?

I really like how Leonardo ai offers a wide range of creative styles, presets, and customization options, which makes it easy to experiment with different themes and visual directions. Whether I need something realistic, artistic, cinematic, or more abstract, there are plenty of choices available that help match the exact mood I’m going for. The interface is clean and beginner friendly, so I don’t feel overwhelmed while using it. Navigation is simple, and adjusting prompts or settings doesn’t require too much technical knowledge. At the same time, it still gives enough advanced controls to fine tune the results when needed. It saves me a lot of time because I can quickly generate high quality, good looking images without spending hours searching for references or doing heavy manual editing. The output quality is consistent, and even small prompt changes can produce noticeably better results, which makes the whole creative process faster and more efficient.

What do you dislike about the product?

One thing I don’t like about Leonardo.Ai is that results can be inconsistent at times. Some generations look great, while others need multiple retries to get the quality right. It can also take a bit of experimenting with settings to fully understand how to get the best output.

What problems is the product solving and how is that benefiting you?

As a freelance graphic designer, I’ve explored many AI tools in 2025, and Leonardo AI stands out as one of the most reliable and versatile platforms I’ve used. At the start, I simply placed short text prompts, and it was able to generate creative images automatically. I found that the more details I provide in prompts, the better and more accurate the results become. This makes the process of creating visuals faster and more efficient than manually searching for stock images or manipulating photos. In my workflow, I use Leonardo AI for a variety of purposes: generating abstract backgrounds, concept art, creative textures, and stock-style images that can be customized for social media posts, website graphics, and client presentations. My company and I use it regularly because it saves time and allows us to experiment with multiple variations quickly. Unlike traditional stock libraries, Leonardo AI produces unique visuals that can be refined and scaled easily. It has become an important tool for brainstorming, creating high-quality graphics, and enhancing my creative output as a graphic designer, making the overall design process smoother and more productive.

What do you dislike about the product?

I don’t like it, mainly because the daily credits are limited, which restricts how often I can generate images and videos. On top of that, most of the more advanced features and models are locked behind paid plans, so it feels like I can’t really use the tool as much as I’d like without upgrading.
