Defining characters

Characters are the most important reusable thing you build in ComicInk. The whole point of "character consistency" — the same person looking the same across 20 pages — depends on you defining each character clearly.

Defining characters is free (0 credits per character avatar). Generating their pages later is what costs credits.

What a character has

• Name — used by the AI to match the character to panels in your synopsis. The names you use in the synopsis must match the names of the characters you've defined.
• Description — physical appearance, personality, key traits. This is what the AI reads to build the avatar and to render the character in panels.
• Avatar — a generated reference image of the character. This is the visual ground truth the AI keeps coming back to.

How to define one

In a series's character section:

1. Click New Character.
2. Enter a name (e.g., "Maya Chen", "Detective Rourke").
3. Write a description: "Mid-twenties, mixed Japanese-American, short black bob with red streak, leather jacket, sharp eyes, scar on left cheek. Wary, sarcastic."
4. Generate the avatar (free). The AI produces a portrait based on the description.
5. Regenerate the avatar if you don't like it (also free) until you have one you'll use as a reference going forward.

What makes a great description

• Specific physical traits beat vague ones. "Tall woman with red hair" is weak. "Six feet tall, freckled, deep-red curls past her shoulders, green eyes, gold hoop earrings" is strong.
• Distinguishing features. Scars, tattoos, a unique outfit, a specific accessory — these become anchors the AI reuses.
• Age and ethnicity if relevant — be specific so the AI doesn't drift across pages.
• Recurring outfit. Comic characters typically wear similar clothes across an issue. Mention the outfit so each page renders it consistently.
• Personality cues affect facial expression. "Always smirking" or "haunted eyes" subtly steers how the character is rendered.

How character consistency works

When you generate a page, the AI:

1. Reads your synopsis or panel description.
2. Identifies which character names appear.
3. Pulls in the avatars of those characters as visual references.
4. Renders the new page with those characters keeping their established look.

If a character on a page looks wrong:

• Check that the synopsis names the character by the same name you used when defining them.
• Check that the avatar itself is good — if the avatar is inconsistent, every page using it will be too.
• Regenerate the page with the correct character assignment (25 credits).

Renaming characters

If you rename a character mid-series, existing pages still reference the old name. Regenerate those pages with the new name to refresh.

Character roster size

You can define as many characters as you want per series. The first 5 characters per issue are free; characters added beyond that cost 10 credits each. See free and paid character slots.

Sharing characters across issues

Characters defined in a series are available to all issues in that series — define your protagonist once and use them across issues 1, 2, 3, etc.

Characters do not transfer between different series. If you have a shared universe across series, you'll define the character separately in each series.
