PixArmory

Plans for PixArmory start at $7.99 a month, and credits drive everything: four credits make one image.

PixArmory is an AI photo editor that transforms, enhances and creates images, with tools for background removal, upscaling, style transfer and image generation.

Starter gives 200 credits, or 50 images, plus image history and HD downloads.

Pro costs $15.99 a month for 600 credits (150 images), faster priority processing and email support.

Studio is $39.99 a month for 2,000 credits (500 images), and it adds batch processing, API access, dedicated servers and 24/7 technical support.

Every plan carries a 30-day money-back guarantee.

If you would rather not subscribe, three one-off credit packs never expire.

Emergency is $4.99 for 80 credits (20 images), Standard is $9.99 for 200 credits, and Value is $24.99 for 600 credits.

Value works out cheapest per image of the three.

The catch is the credit cap: despite the unlimited tool access, the number of images you can produce depends on your plan or pack.
