MIDNIGHT ORANGE STUDIO / AI CHARACTER STORIES

The story waitsfor your reply.

A character chat app for people who live in web novels and role-play threads. You talk to the character, and what you say and choose decides the next scene.

CHARACTER STUDIES / 01—10

Ten strangers, each with an opening line.

Before anyone gets a voice, we work out who they are and where they live. These studies test how far the range can go, from an underground boxer to a teahouse storyteller. They're concept art for now, not characters you can talk to yet.

01 / HOW IT PLAYS

You're not reading the scene. You're in it.

Web fiction never asks what you'd do, and character chats tend to drift after a few messages. We're building the thing in between: a character who talks back, a scene that moves when you choose, and a story that keeps track. Here's how we want it to play.

01

Pick someone

Each character arrives with a past, a way of talking, and something already on their mind.

02

Answer, or decide

Type whatever you'd say. At the moments that matter, the scene stops and asks what you'll do.

03

Live with it

What you said should still matter three scenes later. That's the hard part, and the part we're building toward.

02 / WHAT WE'RE SOLVING

Three things a character has to get right.

01

A face that reacts

When the conversation turns, their expression should turn with it. We're testing this in a separate desktop prototype before wiring it into chat.

02

A voice that holds

A sarcastic courier shouldn't sound like a gentle herbalist by message twenty. Our mobile prototype anchors each voice with a profile and sample dialogue.

03

A memory that counts

Today the prototype keeps track of the recent conversation. Remembering a choice from last week, and letting it bend the plot, comes next.

03 / BUILD STATUS

Two prototypes. No beta yet.

We have a mobile app for finding characters and chatting with them, and a separate desktop experiment where a character reacts on screen. They aren't connected yet, and nothing is open to the public.

Working nowBrowsing characters, text chat with recent context, and on-screen reactions in a standalone experiment.
Building nextConnecting reactions to chat, remembering the choices that matter, and writing scenes that branch.
Before a betaA small closed beta once the core loop holds together and content safety checks are in place. No date yet.

We plan to charge a monthly subscription. Nothing is for sale today, and there's no waitlist to join.

Next, we plan to test Claude API against the problems above: holding a voice over long conversations, keeping track of context, and staying consistent after a story branches. Claude doesn't power the product today, and this is not an Anthropic partnership or endorsement.

MIDNIGHT ORANGE STUDIO / WHY THIS

A good character should remember you.

Readers already argue with characters in comment sections and keep role-play threads going for months. We want to give that energy somewhere to go: a character who answers, remembers what you told them, and lets the story turn because of you. Midnight Orange Studio is an early-stage startup in Seoul working on exactly that.
