AI Character Creator
Create your own AI characters
HammerAI offers a fully private, powerful AI character creator experience. With our desktop app, you can build, design, and chat with AI characters that you customize — from their personality and speech style to their backstory and visual appearance. You have full control over the character's traits, behaviors, and how they interact with you. Whether you're writing a novel, roleplaying, or just experimenting with fictional personalities, HammerAI makes it simple and fun. All chats and character data are saved locally, ensuring your work remains private. You can also combine story writing mode with image generation to bring your characters to life visually. Unlike other platforms, HammerAI offers a blend of local LLMs and easy-to-use tools with zero login required, no subscription pressure, and complete creative freedom. You can even use our advanced system prompt editor to fine-tune the way your character thinks. HammerAI is ideal for writers, roleplayers, or anyone who loves character-based storytelling powered by AI.
🤗 Free
HammerAI is 100% free to chat - both for local models which run in your browser, and cloud-hosted models which run on our servers. You can also write stories, generate images, and build lorebooks ✨
🤫 Private
Cloud-hosted messages are processed on secure servers, or you can choose to run the LLM on your local machine for total privacy. Your messages are not saved anywhere but your computer 🔒
