Promptchan is an online AI-driven creative platform that combines generative image and short-video synthesis with persistent, persona-driven AI characters and chat/voice interactions. The service centers on creating highly customizable characters — often described as “AI girlfriends” — where users can define appearance, personality, outfits, poses, and sexual or fetish preferences; those characters can be used both for one-off image/video generation and ongoing conversational interactions.

The toolset includes multi-style image generation (photorealistic, anime, 3D, illustration), an edit/pose system that lets users adjust composition and body positioning, upscaling and quality options, and short video generation with temporal consistency for character continuity. A community gallery and remixing features let users browse, favorite, and adapt creations made by others. The platform exposes developer-facing endpoints and workflows for automation and integrations, and it uses a credit or “gem” economy where free users receive limited monthly credits and paid subscribers receive larger allotments, priority processing, and access to advanced features such as higher resolutions, video, and API access.

Typical use cases include adult-oriented image and short-video creation, character design for hobbyist or fantasy projects, rapid prototyping of stylized characters, and private conversational/roleplay experiences. The audience is mainly adult creators and consumers seeking uncensored creative freedom, artists who want detailed pose and style control, and developers who want to integrate generation capabilities into other apps. Important caveats for prospective users are the platform’s explicit focus on adult content (with associated moderation and age-verification processes) and that it is a proprietary, hosted service rather than open-source software.
