About this app

─────────────────────────────────────────
KimiAI — Your very own AI character,

Have realistic conversations.

─────────────────────────────────────────

It's not just a "chatbot."

KimiAI's characters learn more and more about you through conversations.

The more you talk, the closer you become, and the more their responses change.

This feeling of "growing a relationship" is KimiAI's greatest charm.

Your ideal AI boyfriend/girlfriend, a reliable senior, a kind family member—

Create as many of the beings you desire as you like, freely.

◆ Talk with your favorite character
The gallery features a wide variety of unique official characters.

Add the character you like to your collection and start a conversation right away.

Of course, you can also create your own character from scratch, or easily create one using a template.

* Customize personality with over 15 personality traits
* Detailed settings for tone of voice, how to address someone, and relationship type (friend/lover/married couple, etc.)
* Freely simulate romance with an AI boyfriend/girlfriend
* Personalize likes and dislikes, and even speaking style
* Automatically generate system prompts with AI (leave it to the AI ​​if you're unsure!)
* Generate original icons with AI

◆ The more you talk, the more the character "gets to know you"
KimiAI has a "closeness system."
As you talk more, your bond with the character deepens,
and their responses, speaking style, and sense of distance gradually change.

They might be a little distant at first.
But before you know it, they'll be using casual language and remembering your preferences.
That change is somehow delightful.

If you tell them your name and introduce yourself, the character will speak to you based on that.

◆ Simple Tricks to Avoid Stumbling Over Conversations
- If you're unsure what to talk about, the AI ​​will suggest topic options.
- The AI ​​automatically generates "recommended situations" for each character. Start your conversation from a scene that interests you.
- If you're unsure how to reply, the AI ​​will suggest response options, so simply choose one.
- If you want to rephrase something, you can freely regenerate or rewind your response.

◆ Use Two Chat Modes
▼ Casual Chat Mode
- 1 point per message, perfect for casual everyday conversations or killing time.
- You can enjoy it essentially for free within the range of the free points you receive daily.

▼ In-Depth Conversation Mode
- 5 points per message, allowing for deeper and more emotional conversations.
- A special time where the character fully engages with you.
- Your intimacy level will also increase significantly.

◆ Choose Your Reply Tempo
▼ Instant Reply Mode
- A fast-paced conversation where you get a reply immediately after sending.
- Ideal for when you want to talk quickly or exchange messages at a good pace.

▼ Real Mode
You'll receive replies after a short delay, just like with a real person.
This special mode lets you experience thatドキドキ (heart-pounding) feeling of waiting after a message has been read.
As your relationship deepens, replies will become faster.

◆ Earn Points Daily
・Receive 20 points automatically every day just by logging in (no action required to receive)
・1 point per message in Chat Mode, 5 points per message in Deep Conversation Mode
・Even if you run out of points, you can immediately resume by purchasing a pack.
