AI companion
An AI companion with a world of their own
Not a chatbot in a box. A character inside a place, with their own language, their own memory of your story, and a private space that stays yours.
What that means here
Company that remembers
A companion here is more than a personality prompt. They live in a world with rules and other people. They remember your chapters. They keep secrets until your character earns them. And when the night ends, everything you two wrote is still there, editable, private, and yours to export.
Start with someone
Private by default
Nobody reads this but you
Your story is yours. We never train AI on your writing. Nobody sees it unless you publish it yourself. And any night you want, you can export everything as a novel, a screenplay, or fanfiction format and take it with you.
Straight answers
What is an AI companion?
A character you spend time with: you play your own character, they play themselves, inside a world that gives the two of you something to do. Unlike a chatbot, they carry a profile the AI reads before every reply, so their voice holds for chapters, and they only know what your character has earned the right to know. Every scene you share becomes part of a story you keep, and the world keeps giving the two of you something new to do, tonight and every night after.
Does an AI companion really remember?
Here, yes. Your scenes become chapters in a real editor, and before every reply the AI reads your story so far, the companion’s profile, and what your character knows. Month-old confessions are still respected in chapter 40. It is memory built like a book, not like a scroll buffer, and it never runs out of pages.
Is it private?
Private is the default. Your story lives in your own space, nobody at Lunafic reads what you write, and nothing goes public unless you publish it yourself. Zero stories are used for AI training, ever. You can also export everything you have written, any time you want, as a novel, a screenplay, or fanfiction format. What you write here belongs to you.
Is it free to start?
Yes, with no credit card. The free tier includes the full studio, every writing format, and a fresh allowance of AI credits every month, which covers dozens of scenes. Paid plans exist for writers who finish what they start: more credits, deeper models, and higher limits. Start free tonight, write the first chapter, and upgrade only when the story asks for it.
