## What is HammerAI?

Chat with thousands of AI characters, roleplay your own stories, generate images, and hear characters speak. HammerAI is the private AI roleplay and character chat app: free to chat, no ads, no tracking, and your chats and characters can stay on your device.

THOUSANDS OF AI CHARACTERS
Browse community-created characters across every genre: fantasy, sci-fi, romance, horror, comedy, and more. Each has a unique personality, backstory, and conversation style. Create your own AI characters from scratch or import them.

AI ROLEPLAY & CHARACTER CHAT
Immersive roleplay conversations with AI characters that remember context and stay in character. Set up your own persona so characters know who they're talking to. Characters have their own voice, and you can choose from over 300 AI voices in multiple languages.

GROUP CHATS
Add multiple AI characters to the same conversation. Watch them interact with each other and with you. Each character maintains their own personality.

STORY WRITING
Co-author stories with AI. Build worlds with lorebooks that define your world's lore, history, and rules so the AI stays consistent across long narratives. You can also generate images for your stories.

IMAGE GENERATION
Generate character portraits, scenes, and illustrations with dozens of AI art models including Flux, Stable
Diffusion, and more.

TEXT-TO-SPEECH
Over 300 AI voices in multiple languages. Give each character their own voice.

CHOOSE YOUR AI MODEL
Most AI chat apps lock you into a single black-box model. HammerAI lets you pick from leading open-source LLMs tuned for roleplay and storytelling: Mythomax, Hermes, Mistral, Lumimaid, Magnum, Euryale, WizardLM, and more. Try a few, find your favorite, or let HammerAI pick a sensible default. Want to dial it in further? Adjust temperature, context window, and system prompt to match your style exactly. Not finding the LLM you want from our options? Use any LLM in the world with our proxy LLM support.

PRIVATE BY DESIGN
Most AI chat apps store every conversation and character on their servers. HammerAI gives you the choice: keep your chats and characters local on your device, or sync them to the cloud if you prefer. Either way, we never run ads and never sell your data.
