About HammerAI
HammerAI is a free AI chatting platform that allows users to interact with AI-powered roleplay characters. The platform emphasizes privacy by processing cloud-hosted messages on secure servers, or users can run language models locally using Ollama on their desktop for complete privacy control. Users can chat with hundreds of customizable AI characters, generate images, write collaborative stories, and build personalized lorebooks and personas. The platform serves creative writers, roleplayers, and storytellers looking for an uncensored, unrestricted AI companion experience. A key distinction is the combination of complete free access with genuine privacy options—users can choose between cloud or local processing without account requirements. One notable limitation is that the platform operates without content filtering, which may limit its appeal to users seeking moderated interactions.
