AI Novel Writing Assistant
Use AI to help write your novel
HammerAI is the perfect AI-powered novel writing assistant. Designed for desktop users who value privacy and creative control, HammerAI allows you to brainstorm ideas, write chapters, build character arcs, and develop entire books — without ever needing to upload your content to the cloud. The story writing interface is fully integrated with a local LLM engine via Ollama, meaning you can work offline and keep your drafts completely secure. You can write in your own voice while receiving AI suggestions to improve pacing, dialogue, and plot development. Our editing tools allow you to format your novel with headings, bold text, colored annotations, and more. HammerAI gives you total freedom to explore genres from fantasy to romance to thrillers, and our story-saving system means you can pick up where you left off anytime. Whether you're a first-time author or a veteran writer, HammerAI is a powerful creative partner that never compromises your data or creativity.
🤗 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 🔒
