About this app

Chat with thousands of AI characters, roleplay your own stories, generate images, and hear characters speak — all for free. HammerAI is the private AI roleplay and character chat app that never tracks you and never shows ads.

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.

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.

IMAGE GENERATION
