Purpose-built for long-form roleplay and creative fiction. No technical setup, no content police, just AI that keeps up with your stories.
Multi-model AI
Persistent memory
Content freedom
Hit a wall mid-scene because the AI refuses mature themes? We get it. Your private fiction shouldn't need a babysitter.
Spent 50 messages building a relationship, and suddenly the AI doesn't remember your character's name? Never again.
Don't want to mess with config files, but simple chatbots feel like writing with training wheels? There's a middle ground.
Switch between Claude Sonnet 4.5, GPT-5, and Gemini 2.5 Pro. Different models for different moods - romantic, action-packed, literary.
Pin critical moments. Your character's backstory, world events, relationships-all remembered across sessions. No more repeating yourself.
Create worlds with their own lore, rules, and history. Use them across multiple stories. Your fantasy kingdom or sci-fi colony stays consistent.
Switch between your characters mid-story. Each maintains their own voice, and personality.
