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 a character costs 10 credits, which includes generating its initial avatar — the same flat cost for every character, whether it's the 1st or the 20th in an issue. See character costs per issue. Generating their pages later costs the normal page rate (50 credits) on top of that.

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.
• Reference photos (optional) — you can upload a face-likeness photo and a separate style-reference image to guide the generated avatar. Uploaded photos are deleted after generation, for privacy — only the generated avatar is kept. If you regenerate later, the edit modal opens so you can re-upload if you want a fresh reference to guide that generation; it's optional.
• 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 the editor's Cast pane (or the Cast section of the Advanced Script Editor):

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 (10 credits). The AI produces a portrait based on the description.
5. Regenerate the avatar if you don't like it until you have one you'll use as a reference going forward. Each regeneration costs 10 credits — there's no free quota, but no hard limit either.

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 (see what costs 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 up to 50 characters per series — the roster is shared across all its issues, and each issue uses only the characters you select for it. Each character costs 10 credits to define, whether it's the 1st or the 50th. See character costs per issue.

AI-invented characters

When the AI writes or expands a script and needs a character you haven't defined — a background extra with a speaking line, say — it can invent one on its own. ComicInk caps this at 5 new AI-invented characters per issue. Beyond that cap, define the character yourself so the AI has something to work from.

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.

Multiple looks for the same character

Need your character in a costume sometimes and civvies other times? Or aged-up in a flashback? See character avatars (different looks) — each character can have up to 3 alternate looks while keeping the same face and body.

Characters without a human body

Not every character has a human body — a dragon, a ghost, a talking vehicle. See non-human cast members for the Form field, which drops the fields that only make sense for a human body and swaps in a body-agnostic reference sheet.
