PromptHero

The pricing page sells two things: subscriptions and credit packs. Starter ($16 a month billed yearly, $194 a year) lists 3,600 total generation credits, and Pro ($24 a month billed yearly, $296 a year) lists 7,200. Credit packs cost $59 for 1,000 credits and $99 for 2,000, never expire and can be bought without a subscription. The page does not say whether the subscription credits are a monthly or a yearly amount, and it shows no credit cost per image or video, so how many pictures a plan produces cannot be worked out from it. Monthly-billing prices were not visible on the yearly view that opened.

The FAQ adds that failed generations are refunded and that some models start at promotional credit prices that rise later, so a cost seen today may change.

On the free plan every creation is public, and credit-pack generations are public too, with stricter content moderation and standard speed. Private, unlisted generations come with Starter and Pro through a Make private action. The privacy policy says public prompts and images are kept indefinitely, while private content stays as long as the account is active. If you delete your account, personal data is removed or anonymised within 30 days, but content that was public may persist in caches or archives.

The terms published in the FAQ go further: contributors grant PromptHero a perpetual licence to display, distribute, sell and make derivatives from what they post, including on other platforms. Anyone who publishes prompts or images there should read that clause first.

The FAQ calls the site crowdsourced and tells users not to rely on the data, and to check that anything they reuse is free of legal charges. The free plan is marked for personal use only. The pages read say nothing about commercial rights on Starter, Pro or credit packs, so confirm with PromptHero support before using output in client or product work.

The privacy policy states that text prompts and any input images go to third-party AI model providers, currently Replicate and Together AI, and that input images are deleted within 24 hours. The service is rated 18+ in app stores because it can show mature AI-generated content, and Pro lists fewer content restrictions.

1. Create a free account and open the prompt collection for one model, such as FLUX, without paying.
2. Generate one image from a harmless invented prompt, for example a paper boat on a pond at dusk.
3. Open the result while signed out or in a private browser window and note whether it can be found and viewed.
4. Look for a Make private action on the free account and note whether it is offered.
5. Note how many generations the free account allows before it stops, and what credit cost is shown for one image.

Accept if the free result is visible to others and the daily limit and credit cost are stated clearly. Reject if the result is hidden from others on a free account or the limits cannot be found. No result is recorded here.
