GUIDE / CHARACTER CHAT

How to build an AI character chat

Beyond being read, a character can talk to readers directly. AI character chat creates a point of contact with fans outside the work itself. This guide covers the settings that make a character sound like themselves, adding standing art and voice, and publishing.

First-time CromStudio users receive 1,000 coins. They can only be spent on generation inside Studio and expire 90 days after they are granted.

Character comes from specifics, not adjectives

Telling an AI a character is "cheerful" or "kind" produces the same replies for everyone. What works is specifics: catchphrases, how they refer to themselves and others, how joy and anger show, topics they avoid, and their attitude to other characters. The persona tab has separate fields for these.

At publishing time, an operating prompt covering persona, world, speech style, permitted topics and forbidden words can be generated by AI in one go (this uses coins). Include which episode they know up to and what counts as common knowledge in their world, and the character stops inventing things outside the setting when readers ask.

  • Fix first-person and second-person forms and sentence endings
  • Describe how each emotion shows (goes quiet when angry, talks fast when excited)
  • Separate what may be discussed from what should be deflected

Replies are dialogue only

What appears in the chat screen is the character's speech. Stage directions like "(smiling)" break immersion. CromStudio strips directions and delivers dialogue only, but adding "no narration" to the speech-style instructions keeps it stable. Even a quiet character should keep speaking; write them as answering in few words rather than not at all.

Add standing art and voice

The chat screen can show full-screen standing art with lip movement matched to speech. It uses the standing art from character creation, so create the model sheet and standing art first if you have none. Expression variants let the display follow the mood of the reply (standing art, expressions and standing video each use coins).

Link a voice preset and the chat speaks. The voice is shared with the character's anime dialogue, so one decision applies across the whole work.

Combine with choice-driven stories

The same character can also carry a branching story where reader choices change the outcome. Stories are written as twelve-scene episodes with parameters such as affinity and hidden events. Readers who grow close through chat move on to the story, a path that exists outside the work. Characters appearing in a story must have their chat published.

Publish to the crom app

From distribution management, set the character's icon, profile text and genre and publish to the crom manga app. Publishing requires agreeing to the core clauses of the distribution terms and declaring that you are of age. A finished work is not required; the character can be published alone. Reader-side charges for chat and story turns are handled by the app, and a share of that revenue goes to the creator at the rates in the terms.

If you change settings after publishing, update from distribution management. The lead character of a published story cannot be swapped for another, so fix the lead before publishing a story.

Frequently asked questions

Does building a character chat cost anything?

Entering the persona, distribution settings and publishing itself are free. Generating standing art, voice or the operating prompt with AI uses coins.

Can I control what the character says?

Giving personality, speech style, permitted topics and forbidden words as settings keeps replies in character. Writing that off-topic questions should be deflected is effective.

Which languages can readers chat in?

Readers chat in the app's display language and replies come back in that language.

Can I start with just a character and no manga?

Yes. Start by publishing the chat, then add stories and manga later.
