Rivata User Guide

As of September 24, 2026 · Provided by WebAppBiz (707kib@gmail.com)

Rivata is a program where you talk by voice with an AI character on the screen. It is not a chatbot where you type text; you can see their face and hear their voice, and their facial expressions and gestures move while they speak. You can use the same account on Android phones, iPhones, and Windows PCs, and memories and settings are automatically synced between devices. This guide describes the steps for using it in order, starting from the moment you first turn it on.

1. Installation and Login

  1. Phone — Download Rivata from Google Play or the App Store. When you open it for the first time, agree to the terms of use and log in with a Google account or Apple account. There is no separate sign-up process or phone number verification.
  2. PC — Download the PC version from the introduction page, unzip it, and run it. Since the installation file fills in what it needs after being downloaded, it takes some preparation time for the first time.
  3. Same Account — If you log in with the same account on your phone and PC, the two devices will be linked as belonging to one person.

The PC requires a microphone and speakers. If you have a graphics card, voice recognition is fast, but even without one, you can talk through text.

2. Choosing a Character

Each character is a different person. Their name, age, nationality, occupation, hometown, family, personality, way of speaking, and backstory are all set individually, and they speak accordingly. When you first turn on the app, four default characters are included, so you can start talking right away.

You can read about what makes each character different one by one in the character introduction.

3. Conversing by voice

  1. Just turn on the microphone button and start talking. You can call them by name or get straight to the point.
  2. The character will understand and reply out loud in a natural voice.
  3. You can interrupt while they are speaking. Just like talking to a person, they will follow along even if you cut them off and talk about something else.
  4. It doesn't have to be a quiet place. You can adjust noise cancellation and echo reduction in the settings.

When you want to type, you can send text. The conversation continues even if you mix the two methods.

4. Managing memories

Rivata remembers things learned during conversations. It keeps track of names, things you like, what you do, today's tasks, and even minor things mentioned in passing, and brings them up first next time. This is why the longer you talk, the more it feels like someone who knows you.

Memory tabYou can see everything that has been remembered so far.
Adding manuallyYou can write things down yourself line by line, like "I only drink iced coffee."
Edit/DeleteYou can edit incorrect memories and delete memories you don't want to keep right on the spot.
Detailed profileIf you fill out items like your first meeting, memories, preferences, and speech habits in the table, they will be reflected in the conversation.

5. Customizing your character to your liking

You can edit the name, personality, speech style, profile, and memories. For example, if you change the character's name to what you want to call them, make their speech style more casual, or write down a different job for them, they will change accordingly. Once you edit something, we won't overwrite it again.

You can also create your own character by uploading a single photo. The creation process is handled on our server, and once it's finished, it will arrive in the app.

6. Alarms and schedules

If you say things like "Wake me up at 7 o'clock every morning" or "Remind me to take my medicine at 9 o'clock," it will notify you at those times. When the time comes, the character will speak to you in their voice instead of a mechanical sound. It is also used to help seniors living alone keep track of their medication and meal times.

7. Weather, news, and search

If you ask about today's weather, major news, or things you're curious about by voice, it will find the information and answer in its voice. If you say "Give me a briefing" in the morning, it will summarize the weather, schedule, and news all at once. You can turn off unnecessary features in the settings, and once turned off, those features will not function at all.

8. Using phone and PC together

If you log in with the same account, memories, settings, voices, and characters are automatically synced between your phone and PC. You can continue a conversation you started on your phone on your way home from work on a large screen at your desk. Changes made on any device are reflected on other devices.

9. Language

The screen and the character's speech are available in thirty languages. When you change the language, not only does the text on the screen change, but the character's name, introduction, and profile also change to that language. However, text that you have edited yourself is left as it is.

10. Privacy and Deletion

Conversations and memories are stored on your device and account. You can delete a single memory, a single character, or your entire account at any time within the app. When you delete your account, the data on the server is also deleted. Details are written in the Privacy Policy.
