Hammerai
HammerAI provides free, private AI-powered character chat experiences and creative tools. Users can click on ready-made characters to start unlimited conversations, or create their own characters, write stories, generate images, and build lorebooks. HammerAI supports both cloud-hosted models that run on secure servers and local models that run through a desktop app for users who want to keep everything on their own machines.
The product is aimed at people who want conversational roleplay with AI characters, writers and creators who want story and image generation, and privacy-conscious users who prefer local model execution. The interface includes organization features like My Characters, My Chats, My Images, and favorites, plus category filters and sorting to browse available characters.
