Using Nisatsu safely

Two things here are written by a language model, not by a person:

• Stories. When you ask for a story, a model writes it from your topic and the words you already know. Stories other learners published were written the same way.
• Ask Nisatsu AI. When you tap a phrase in the reader and ask about it, a model writes the answer.

Nobody reads either one before you do. A content filter checks both, on the way in and on the way out, and blocks sexual content, graphic violence, and self-harm. A filter is not a proofreader: it looks for harm, not for mistakes. What we will and will not host is set out in the Community Guidelines.

A language model writes a wrong answer in the same confident voice it writes a right one. There's no hesitation to read, no face to check.

So it can hand you a reading that doesn't exist, a word nobody uses, or a grammar rule it invented, and none of that will look any different from the parts it got right. Being confident isn't the same as being correct, and here it tells you nothing either way.

Before you rely on something it told you, check it somewhere else. The dictionary entry in the app, a textbook, a teacher, or someone who speaks the language will settle it faster than asking the model again.

You can report anything in Nisatsu that shouldn't be there.

• An Ask Nisatsu AI answer. Tap Report under the answer, then say whether it was wrong, harmful, off the topic you asked about, or something else.
• A story someone published. Open the story's options menu and choose Report story.
• Someone's profile. Shared profiles carry Report profile and Block profile. Blocking takes effect right away, in both directions.

Reports go to a person on our team. They do not go back into the model, and reporting does not change the answer already on your screen or delete your chat. If something needs attention sooner than a queue, email contact@nisatsu.com instead of waiting.

Ask Nisatsu explains sentences. That's the whole job. It isn't a counselor, a doctor, or a friend. It doesn't know you, it won't notice that you're having a bad week, and it isn't a safe place to work something difficult out.

If you're struggling with something, tell a person: a parent or guardian, a teacher, a school counselor, or a crisis line. They're free, they're confidential, and you don't have to be in danger to call one.

• In the US and Canada, call or text 988.
• Anywhere else, findahelpline.com lists lines by country.

Your Ask Nisatsu questions and the answers are saved to your account, so the chat is still there when you come back to that phrase.

To write an answer we send the question, the phrase and the sentence it sits in, and the recent turns of that chat to OpenAI. We do not send your name, email, phone number, or account ID with it, and none of it is used to train anyone's model.

Deleting your account deletes those chats with it (Account → Settings → Privacy & data → Delete your account). The Privacy policy has the full version, including what survives and for how long.

You have to be 13 or older to have a Nisatsu account, or 16 or older in the EU and EEA. We ask you to confirm that when you create the account, and we never ask for your date of birth.

If you are under 18, tell a parent or guardian you are using an app where a language model writes the stories and answers your questions. It is their call as much as yours.

A parent or guardian who wants an account closed and its data deleted can email contact@nisatsu.com. The steps, the evidence we ask for, and how long it takes are in the Children section of the Privacy policy.

Write to us at contact@nisatsu.com. A real person reads it.
