Koitone: AI Boyfriend Chat

Koitone is an AI boyfriend and character chat app with a K-drama feel. Create an original character, explore fictional stories, and find your own way into a world of conversation and illustrated scenes.

CHARACTERS WITH YOUR OWN IDEAS
Choose a name, personality, speaking style, relationship and backstory. Start with a few settings or add the details you already imagine. Select a realistic or anime-inspired art style, then give your character a setting to belong to. AI can suggest a world draft from your choices, so you can begin without writing a long introduction.

MAKE A CHARACTER PORTRAIT
Combine appearance options and a written description, or add a reference image you have permission to use. Explore a hairstyle, outfit or expression that fits your fictional cast. A reference photo is optional, and generated results vary with your input.

CONVERSATION THAT MOVES A SCENE
Write a greeting, describe a setting or tell the character what happens next. Replies draw on the character's personality, speaking style and conversation context. Try a rainy cafe, a surprising meeting or an ordinary day with an unexpected turn.

DISCOVER AN ORIGINAL CAST
Browse characters with different backgrounds, including doctors, pilots, performers and heirs. Read their introductions to find a setting that interests you. Choose a character to start exploring, or use the creator to build an original one.

SEE WHAT THE CHARACTER REMEMBERS
Review saved character memories, correct a mistaken detail, pin an important fact or delete an unwanted memory card. This makes it easier to see which information has been recorded while your story develops. AI does not remember everything perfectly. Removing a memory card does not erase the existing conversation history or its summaries.

READ, CHOOSE AND CONTINUE
Story episodes introduce a fictional world and its cast. Read the scenes, choose from the options offered by that episode, and continue into conversation. Revisit your chosen path through the episode history. It is a way to enjoy interactive fiction when you want a prepared starting point, or to find inspiration before writing your own response. Episodes and available choices depend on the content.

COLLECT SCENE ILLUSTRATIONS
As conversations progress and interaction levels increase, new character photos become available. Collect scene images with different rarity levels in each character's album. Locked images can be opened by reaching the required level or through the available Gold coin unlock option.

IMAGINE A CUSTOM SCENE
Use a character's main portrait as a reference and describe the place or atmosphere for a new photo. Generated photos are added to your personal album. You can use another screen while a request is processing and check the notification list when it is ready. Generation is subject to availability, usage conditions and any displayed Gold coin cost.

KEEP CREATING AT YOUR PACE
Keep your own character private, or choose to publish it for other people to discover. Start with a short conversation, try an episode, or spend time developing the character's personality and setting. Koitone suits readers of visual novels, interactive fiction fans, roleplay writers and anyone who likes creating original characters and collecting their illustrations.

FICTION AND PURCHASES
Koitone is a creative entertainment service. Characters, conversations and images are fictional and may be AI-generated; they do not represent real people or facts. You can start for free. Some conversations and image features have limits or require payment. Optional Basic/Pro monthly memberships, Blue coins for conversations and Gold coins for image features are available. Check the purchase screen for current prices and allowances. Subscriptions renew automatically unless cancelled. Manage or cancel through the subscription settings of the store where you purchased.
