Fast and Reliable AI for Concept Art and Design Workflow
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.
Leonardo AI: Fast, High-Quality Image Generation with Excellent Prompt Handling
What do you like best about the product?

Generation is also fast while still maintaining good output quality. I mainly use it to create YouTube thumbnails and cinematic visuals, and it fits that workflow well.
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.

Improving guidance, tooltips, or presets for common use cases would make the experience smoother, especially for users who are just getting started. While results are generally good, having stronger tools to lock in a specific style or character across multiple generations would be a big plus. It's difficult at the start, but when you use it on a daily basis you get used to it.
