Guide

Getting started

Tap “Try for free” – Nika's DMs @Nika_NivaAi will open in Telegram. Write her anything, even “hi”.
She'll reply with a message that has a “Перейти в бота” (Go to bot) button. In the bot, tap “Подтвердить” (Confirm): this confirms that you're 18 or older and that you agree to the privacy policy, terms and public offer.
The Free plan turns on right away, and Nika will reply in her DMs. She doesn't read messages sent before you confirm.

Optional: sign up with Telegram, Google or email.
Your profile has the same things as the bot: subscription, credits, model, Nika's settings, support.

01
Chatting in DMs

A regular chat in Telegram. Write as you would to a person; you can send several messages in a row, and she'll answer them all at once.
02
The next day

Nika remembers what you talked about and may ask on her own how it all turned out.

Nika doesn't reply instantly and sometimes types with pauses.
At night she replies but doesn't text first.
If she remembered something wrong, tell her: the new fact replaces the old one. If something never happened, say so, and she'll stop relying on it.

The Free plan – a weekly limit with no purchase. Usage is counted over the last 7 days, and the limit renews on its own. It's larger in the first days and gradually drops to a constant level over the week.
When the limit runs out, you'll get the message “Недельный лимит бесплатного плана исчерпан” (Free plan weekly limit reached) and the time when it renews.
After that – a subscription or replies paid with credits. Plans and prices are on the “Pricing” page.

In the bot @NiVaAibot, the “Настройки Ники” (Nika's settings) menu section: the model, how often Nika texts first (never, about once a day, every 4 hours or every 2 hours) and what she processes: photos, voice messages, video messages, videos, links. Texting first and processing attachments use up the limit or credits.
The “Ты и Ника” (You and Nika) button is there too: time zone, what Nika calls you and what you call her, “Что Ника помнит” (What Nika remembers).
You can also switch the model with the /anima, /levia, /lux commands in Nika's DMs. How Anima 3, Levia 3 and Lux 3 differ – on the “Models” page.
On the site – in your profile, the “Nika's settings” section.

You can add Nika to a group chat: “Ника в чат” (Nika in Chat) in the bot or in your profile, the “Подписки” (Subscriptions) section.
Replies in the chat are paid with the credits of whoever added her.
In the chat she replies when someone addresses her: by name, with an @ mention or by replying to her message.

You got a limit message (“Недельный лимит бесплатного плана исчерпан” or “Лимит исчерпан до…”, Limit reached until…): you have no access right now. The renewal time is in the message, with the “Купить кредиты” (Buy credits) and “Обновить план” (Upgrade plan) buttons below it. When access returns, the message disappears on its own.
You got a message with the “Перейти в бота” (Go to bot) button: you haven't confirmed yet. Tap it, then “Подтвердить” (Confirm).
You got “Ошибка обработки запроса. Выполняется повторная попытка” (Request processing error. Retrying): the reply is retried automatically. If you end up with “Не получилось ответить” (Couldn't reply), write again.
Whether Nika is working right now – see status.niva.company.
If everything is fine but there's no reply, write again. Still nothing – contact support: in your profile, the “Поддержка” (Support) section, with the “Поддержка” button in the bot or at support@niva.company. The reply will come in Telegram.
Paid but no access: write to support and attach the transaction.
