    Real-Time AI Sketching with Generous Free Generations and Commercial Rights

    Reviewed on Jun 13, 2026
    Review provided by G2
    What do you like best about the product?
    1. Leonardo.Ai lets users sketch and paint while the AI updates the image at the same time, based on their prompts and drawings.
    2. On the free tier, users get around 150 image generations per day.
    3. All images come with commercial rights.
    What do you dislike about the product?
    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 problems is the product solving and how is that benefiting you?
    It helps us generate images with commercial rights for our internal tools and platforms. With model training, we can also create customised images tailored to our product use case and aligned with our customers’ behaviour.

    Leonardo Ai is one of the first ones in the market and in my opinion one of the best AI image production software that is currently on the market. They have an incredible catalogue of tools and you can't beat the pricing. It's easy to use and good on your eyes, doesn't stand out and poke your vision. Fast creation and a range of possiblities.

    If I would cancel my subscription I would lose all my rolled and accumulated credits.

    Leonardo Ai solves my need for fast and quality artists and many different kinds of art, such as coloring books for kids and adults, something I use most.

    Leonardo AI: Fast, High-Quality Image Generation with Excellent Prompt Handling

    Reviewed on Jan 21, 2026
    Review provided by G2
    What do you like best about the product?
    Some of the features I like in Leonardo AI are its high-quality image generation, especially the strong, realistic styles, along with excellent prompt handling. 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.
    What problems is the product solving and how is that benefiting you?
    Thanks to its fast visual generation, it saves me a lot of time compared with manually designing every element for my Youtube channel.

    I use Leonardo.Ai for image generation and appreciate its good ability to create images with the finest quality. What stands out for me is the faster and accurate image generation, along with the accuracy and perfection it offers.
    What do you dislike about the product?
    Image understanding ability should be improved. Basically, humans are weak in prompt generation, so if Leonardo makes clarification on what a human needs, then we can see improved Leonardo.
    What problems is the product solving and how is that benefiting you?
    I use Leonardo.Ai for image generation because it creates high-quality images quickly and accurately.

    What do you like best about the product?
    The best part is that if anyone doesn't know how to right a perfect prompt in order to get the desired image then it provides an option to just type your ideas and it will generate a perfect prompt to generate the exact image you want.
    It not only generates image but also provides wide range of image editing tools to enhance your image or edit your video.
    There are various AI models available to choose from. Which can generate different types of images with a same prompt. You can also upload your image to take it as a reference to generate your desired image or video.
    More detailed features available for video making like different camera sequence, angles and shots from different perspectives. It's a complete package for a film makers.
    What do you dislike about the product?
    For video generation, paid version works better because more credits are required for image to video generation. Though, it's worth it.
    What problems is the product solving and how is that benefiting you?
    It’s a comprehensive platform for filmmakers and professional content creators because, once you have a paid version, you get access to a wide range of features. You can use it across different platforms like Android and Apple, and it works smoothly. You can also subscribe as a team, which makes it easy to use and manage together.

    Leonardo.Ai Boosts Content Creation with High-Quality Output

    Reviewed on Jan 08, 2026
    Review provided by G2
    What do you like best about the product?
    I like Leonardo.Ai for its ability to generate high-quality images and videos, which saves me a lot of time as I post daily on my Instagram page. The images don't expire from the gallery, and there are numerous models available. I also appreciate the daily free credits, which is a bonus. The initial setup is super easy and user-friendly. My team switched to Leonardo.Ai from another service because of its cheaper options and better quality.
    What do you dislike about the product?
    Sometimes I don't get the result I expect even after putting the detailed prompt. Also, on a few models, the cost of credits is very high. Only these things I see require improvement.
    What problems is the product solving and how is that benefiting you?
    I run an Instagram page and Leonardo.Ai saves me time by generating high-quality images daily, allowing me to post consistently without spending hours editing.

    Beautiful Images, But Lacks Intuition in Advanced Features

    Reviewed on Dec 18, 2025
    Review provided by G2
    What do you like best about the product?
    I like that Leonardo.Ai creates very beautiful images with a very powerful and beautiful graphic style, according to what I need.
    What do you dislike about the product?
    There are styles that I feel still need work on UX issues. Sometimes there are things where it's not just about creating an image, but creating a more complex elaboration of the image, it's not so intuitive to do. I wanted to make an image with the style of another or a design within another and it wasn't easy to do, despite them stating it.
    What problems is the product solving and how is that benefiting you?
    Leonardo.Ai helps me create images with personalized and beautiful styles, and also short video clips, using different tools for specific aesthetics.
