Harpy

Harpy is a free online platform that enables users to engage in interactive conversations with thousands of AI-generated characters. The service offers both one-on-one private chats and group chats where multiple AI characters can interact simultaneously, creating a dynamic social experience. Users can participate in roleplay scenarios, build narrative storylines, and explore a wide variety of fictional personas ranging from historical figures to original creations. The platform does not require an account to start chatting, lowering the barrier for immediate exploration. A central feature of Harpy is its character creation system. Users can design their own AI bots by defining personality traits, backstories, dialogue styles, and visual appearances. These custom characters can then be shared with the community or kept private. The platform supports multiple AI models, allowing users to switch between different underlying engines to adjust response quality, creativity, or speed. Harpy also includes community forums accessible from the top navigation bar. These forums serve as a space for users to discuss characters, share prompts, give feedback, and collaborate on story arcs. Event creation is another notable functionality: users can organize themed roleplay events, such as "History Unfolded" where participants build bots rooted in real historical periods or reimagine alternative timelines. These events encourage collective storytelling and add structured activities beyond freeform chat. For deeper customization, Harpy provides prompt presets located in Chat Settings. Users can save and load predefined prompt templates that control character behavior, conversation tone, or specific narrative constraints.
