About the Service

prompts3 is a prompt catalog service where you can browse, copy, and customize AI image prompts, request image generation, and where advertisers can register campaign creatives.

Service Overview

prompts3 is a free catalog service that lets you browse, search, and copy Korean-language prompts for AI image generation. It is available on the web (prompts3.com) and as iOS and Android apps.
Users can view each prompt's title, description, category, example images, and input fields, and edit them to suit their needs.
When you use the general catalog, prompts3 does not automatically submit prompts to external image generation services on your behalf. Copied prompts are entered directly into external services such as ChatGPT or Google Gemini.
AI-assisted features within the service — such as the prompt-writing chat, image analysis, and search intent analysis — help you prepare text and materials; they do not guarantee the output quality or policy enforcement of external models.
The service is operated by SI (에스아이, siaisoft). Operational inquiries and rights requests are accepted at [email protected].

Features for General Users

Without an account: catalog search, category filters, prompt copying, opening in ChatGPT, and enlarged image viewing.
Members signed in with Apple/Google: favorites, recently used, collections (topic-based folders — automatically synced across web and app devices), notification center (read/cleared states synced), nickname and profile photo, image generation requests, and account deletion. On desktop web, these are available from the quick menu under the profile icon at the top right; in the app, from My Page.
A nickname is required to use account activity features. Your nickname is displayed on your requests and published items.
Image generation requests: submit a title and description (optionally with a reference image), and generation proceeds after automated review. Completion or rejection results are shown in My Images and in notifications, and the mobile app also sends push notifications. Generated works are accepted as asset candidates that may be published publicly in the catalog (Article 4 of the Terms of Service).
Some convenience data such as favorites, recent inputs, and screen state may remain in your browser or device storage, while collections and notification states are stored with your account and appear the same on all devices.
Prompts and example images are creative aids and reference materials; we do not guarantee any specific generation result, accuracy, commercial suitability, or absence of rights infringement.

Advertiser Features

Advertisers can use the separate advertiser console (desktop web) to sign up and log in with an email verification code (OTP), submit business information, register ad creatives, make payments, and check campaign status.
Advertisers who have completed business verification can apply for in-feed card ads, and can prepare creatives either by uploading a banner for AI analysis or by generating i2i ad images from logo or product photos. Ad video uploads are also supported.
Users under the age of 14 cannot sign up, and minor advertisers require the consent of a legal representative.
Payments are processed by Toss Payments; original payment details such as card numbers are held by Toss Payments and are not stored by prompts3.

Ads and Affiliate Content

Some cards, recommendation areas, or links within the service may be advertising or affiliate content, and are marked with an 'Ad' label so users can recognize them.
Ad products are operated as inline ads between cards and are displayed after admin review, business verification, payment confirmation, and creative policy checks. Upon payment, the display period is set or extended in units of 1 week or 1 month.
Google AdSense ads may appear in some slots that have no house ads; in that case, matters related to personalized advertising follow the Privacy Policy.
Ads for adult content, gambling or speculative services, illegal financial services, misleading efficacy claims, political advertising, false or exaggerated advertising, or ads highly likely to infringe others' rights may be refused or discontinued.
Clicking an ad may take you to an external site; the products, payments, privacy practices, and terms of external sites follow the policies of the respective advertiser or external site.

Payments and Refunds

In-feed card ads are prepaid flat-rate products; 1-week and 1-month display options are currently offered.
For ad placements not yet served, you may withdraw your order within 7 days of the payment date; impressions already served are not refundable.
Refund requests should be sent to [email protected] and include your advertiser account information, payment date, campaign name, and reason for the refund.

Before You Use

Image generation results may vary depending on the external model used, its settings, input images, policies, and account status.
Trademarks, people, characters, titles of works, and platform names included in prompts may be descriptive references only and do not imply any affiliation, sponsorship, or official relationship with the respective rights holders.
Prompts3 entries are not verbatim copies of external references; they are restructured into a prompt schema. Upon a rights holder's request, we will take necessary measures such as attribution, modification, or removal (see the Copyright Notice).
Before using generated outputs commercially, please verify for yourself that they do not contain third-party copyrights, trademarks, or likenesses.
