Pricing models across the reviewed tools vary between per-image/token economics and subscription/credit-based tiers. RAWSHOT AI is the most explicit in the reviews, at approximately $0.50 per image (about five tokens per generation) with a 7-day free trial offering 30 tokens and the note that failed generations return tokens. Photoroom, Super8, Modelfy, Hypotenuse AI, ProntoShoot, Eightcube, Pixelbin, and BackdropBoost are generally subscription and/or usage/credits based, meaning your monthly cost scales with generation volume and any included limits. The Shopify app “AI Background Generator” is subscription-based with usage limits, so you should confirm exact plan tier pricing directly on the app listing before scaling.
