Shapes

Shapes (talk.shapes.inc) is the #1 multiplayer AI app where users can talk to AI characters, real people, or both in shared group chats. Users can create custom AI characters called 'Shapes' — giving them personalities, memories, and voices — and run them on 300+ AI models including GPT, Claude, Gemini, and more. Shapes can send voice messages, generate images, read PDFs, write code, search the web, and proactively initiate conversations, making them full participants in group chats rather than passive bots.
