AI Roleplay Studio

AI Roleplay Studio is a browser-based tool for creating fictional characters and experiencing stories with them, powered by Google Gemini AI. Two interaction modes, fully customizable characters, and persistent memory — no servers, no accounts, no data collection.

Bring Your Own Key — free API key from Google AI Studio. Your key and your conversations never leave your device.

📖 Narrative Story Mode The AI writes in third person like a literary narrator. It describes the scene, handles side characters, and builds the story alongside you.

💬 Casual Chat Mode Talk directly to your character like a messaging app. No narrator — just natural conversation.

🎭 Character Editor Design characters from scratch: name, personality, backstory, likes, dislikes, and opening situation. Import and export characters as JSON to share with others.

🧠 Long-Term Memory The tool automatically summarizes old conversations so your character remembers what happened — even across long sessions.

🔒 Privacy by design No accounts. No backend. Your API key and stories live only in your browser's localStorage.
