A story you write together, checking what it remembers

Each story has its own memory notebook, so you can see and correct characters and promises at any time. You always decide where the story goes. Grow a story slowly with fictional adult characters, in Japanese.

What you can do

Write a story at your own pace, checking what it remembers

01

See for yourself what the story remembers

Characters, promises, key events and the current scene are kept in a memory notebook for each story. New memories arrive for review, and only the ones you approve are used going forward. If something is wrong, edit or delete it.

02

You always decide where the story goes

Set the directions you want and the topics to avoid. By default, the story never decides your character's lines, actions or feelings for you. Regenerate any reply you don't like. Going back to a save point restores both the scene and the memories.

App screen
03

Price and remaining replies are always clear

The monthly plan is shown in yen, tax included. Before buying, you can check the renewal date and the limit of 1,000 replies per billing period. There are no coins or add-on purchases. After you reach the limit, you can still read your history and memory notebook.

04

If the connection drops, your story is safe

You can tell on screen what is sending, saved or failed. Messages that didn't send can be resent with the text kept. If the app closes, you can resume from the last saved scene and the draft on your device.

How it works

Getting started

  1. Sign up with email and review the terms

    Confirm that this is a service for writing stories with a fictional AI, its adult-only rating and the range of content, then sign up with an email address. You don't need to give your real name.

  2. Choose a story partner or create one

    Choose from six or more original adult characters by reading their profiles and sample conversations. You can also create your own private character by setting a name, age, tone, relationship and setting.

  3. Choose a writing style and begin

    Compare samples and pick, for each story, short dialogue or richer scene description. Then continue the story at the end of the day, at your own pace.

We use processors that don't train on your conversations

Replies are generated by processors under terms that do not use your conversations for training. Where data goes and why is set out in the privacy notice. Conversation text is attached to a bug report only when you choose to attach it.

No coins or add-on purchases

The memory notebook is included in every plan. Reaching the limit never opens a purchase screen on its own. Retries caused by connection failures or system errors don't count toward your usage.

You decide what data to keep or delete

You can stop saving long-term memories at any time. You can request deletion of a single story or your whole account from Settings. Data you ask to delete is removed from generation right away, deleted from our systems within 30 days and from backups within 90 days. Contract records that the law requires us to keep are managed separately, and we explain how.

FAQ

FAQ

Will it remember everything I say?

We can't promise it remembers everything. You can check what the story is referring to in the memory notebook. Only memories you approve are used going forward, and memories from one story are never used in another.

How much does it cost?

The free trial includes up to 10 replies a day. The monthly plan includes up to 1,000 replies per billing period. Check the monthly price with tax and the auto-renewal date on the purchase screen. You can see your remaining replies and next renewal date in Settings at any time.

What kind of stories can I make?

Everyday and romance stories with fictional adult characters. We can't accept explicit sexual content or romantic or sexual settings involving minors. In those cases, we suggest ideas you can enjoy within the allowed range. Important changes to the content range or style are announced with their effective date.

Can I use it without saving memories?

Yes. Even without agreeing to save long-term memories, you can have conversations that aren't kept. You can change this later in Settings.
