Lunafic V4
Lunafic V4 is the current version of Lunafic, released in October 2026. Lunafic was a professional writing tool that turned into roleplay. You play your own character inside a story world, the AI plays everyone else in their native language, and the story remembers every chapter.
We made V4 because many new players opened a world, typed "Hi" to test it, and did not know what to do next. So V4 makes roleplay easier to start and easier to understand.
New in V4
Someone else builds the world and you play it, like visiting another player's world in a co-op game. The world, its characters, and its wiki stay with the person who built it. Your story is yours, and you can edit any line of it like a book.
When you press Play, you choose your hero, a role the author made or your own character, then pick how the story opens from a few starting choices. Some worlds have endings to reach, and locked endings show a hint so you know what to aim for. Worlds without roles are free play.
Players of a Playable World always play in MC Mode. MC means main character, the character you play, and the AI never writes your character's dialogue, thoughts, or actions. The person who built the world gets two more options in their own world. The MC picker lets them step into any character of the world. Author Mode lets them stop playing a character and tell the AI what happens, then the AI writes the scene with every character.
The person who builds a world adds pictures for its big moments. While you play, the AI shows the right picture when that moment happens. The author makes these pictures, they are not generated while you play.
Memory is what the AI remembers about your story. Press Memory above the reply line or type /memory to see what your last reply used, and fix the memory of any chapter or a promise the AI quotes wrong. This is on paid plans.
Tap Aa and pick Lunafic, Visual novel, Chat, or Light novel. The same story in four looks, with paper colors to match.
Narrative settings has a new Writing tab that works like the options screen of a game. Pick the story feel, the reply length, whether your moves can fail, and how often the characters take the lead.
Every screen was redrawn for the phone first, then brought to desktop, so there are fewer things on the screen at once.
Connect Lunafic to Claude, ChatGPT or Gemini once, then ask about your worlds and stories in plain words. It can read your stories, it never changes them.

What you get
V4 changed how you start. These stayed at the heart of it.
The person who builds a world prepares pictures for its big moments. When that moment happens in your story, the picture shows up right in the reply.
Many AI roleplay apps end a line by jumping ahead, telling you a detail will matter later. Lunafic narration stays in the moment with your character, so what happens next is still yours to decide.
Chapter forty still knows what happened in chapter four. Older parts of the story fold into a recap by themselves, so you never manage memory by hand.
You write your character. The AI plays everyone else and stops when it is your turn, so it never writes your words, thoughts, or actions.
Your story looks like a normal roleplay, but every line can be changed. When the AI gets a name wrong, tap it and fix the word instead of paying for a retry.
Characters can speak their own language, like Japanese, with the translation right under each line, so they sound the way they should.
Straight answers about V4
Lunafic V4 is the current version of Lunafic, released in October 2026. Lunafic is AI roleplay built on a professional writing engine, because it was a writing tool for novelists and screenwriters before it turned into roleplay. You play your own character inside a story world, the AI plays every other character in their own speech styles, the story is saved as chapters and remembered across all of them, and the world shows its own pictures at its big moments. V4 focuses on making roleplay easy to start for players who never roleplayed before.
V3 brought Lunafic back to playing inside stories, on top of the writing engine built for professional writers. V4 keeps that engine and redraws every screen for the phone first. It adds Playable Worlds you play like co-op in a game, a hero and starting choices when you press play, scene pictures that appear at the right moment, four reading looks, and a Memory dialog that shows and fixes what the AI remembers.
Yes, Lunafic V4 is free to start and needs no credit card. MC Mode, the long story memory, Playable Worlds, and scene pictures work on every plan. The plans differ by how much AI usage you get each month and a few Free limits, like the number of story notes, and on Free the Memory dialog, search, and Find and Replace are locked. Paid plans are for players who play long stories every day and want more AI usage.
You play your character, the AI plays everyone else, and the story remembers every chapter.
