    The catch
    Getting exactly what you pictured takes practice, and you'll learn a lot of prompt vocabulary.
    Free plan
    No free plan is listed.
    Paid plans

  2. Number 2: Adobe Firefly

    Adobe

    8.2 / 10
    Best for beginners

    Friendly to start with and tied into Adobe's apps. A good pick if you want images for work and already use Photoshop or Express.

    Use it for
    Generating images, extending photos and swapping out backgrounds.
    The catch
    Adobe says images from Firefly's own models are safe for commercial use. Images from partner models, such as Google's or OpenAI's, are your responsibility.
    Free plan
    Free daily generations, no plan needed.
    Paid plans
    Firefly Standard is £9.98 a month including VAT, with 2,000 generative credits. Adobe Firefly pricing (opens in a new tab)

  3. Number 3: Stable Diffusion

    Stability AI

    8.0 / 10

    Use it for
    Custom styles, running image generation locally and building it into your own apps.
    The catch
    Setup and a decent GPU are part of the deal. Businesses earning over US$1 million a year need a paid Enterprise licence.
