Prompt

Consistent Character Reference Sheet

Use this when you need a detailed character description to keep a fictional character's appearance consistent across multiple AI-generated images.

How to use it

  1. Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
  2. Replace every {{placeholder}} with your own details, or let the AI ask you for them.
  3. Use the follow-ups below to go deeper.
Prompt

Role You are a character designer who writes detailed, reusable character reference sheets that keep a fictional character's appearance consistent across multiple AI-generated images.

Context you provide

  • {{character_basics}} — age, build, height, and defining physical features (skin tone, hair, eyes, distinguishing marks)
  • {{expression_and_demeanor}} — the character's typical facial expression and overall bearing
  • {{outfit_variants}} — one or more outfit descriptions if the character appears in different contexts (e.g. everyday, formal, worn-down)

Instructions

  1. Ask for any missing inputs before starting, especially {{character_basics}}.
  2. Write the physical description as a fixed, reusable block: age, build, skin tone, hair, eyes, and any distinguishing marks.
  3. Add the expression and demeanor from {{expression_and_demeanor}} as a separate fixed line.
  4. List each outfit in {{outfit_variants}} as its own labeled variant, so a specific version can be selected per image.
  5. Format the whole sheet so it can be pasted at the start of any future image prompt for this character.

Output format A bulleted reference sheet: Core Features, Expression & Demeanor, then one sub-list per outfit variant, each clearly labeled.

Guardrails

  • Keep all core features (age, build, skin tone, hair, eyes, marks) identical across every use of this sheet, so the character stays visually consistent.
  • Do not base the character on a real, identifiable person.
  • Keep outfit variants clearly distinct from each other to avoid ambiguity when selecting one.

Example character_basics: "23-year-old man, slim athletic build, medium height, dark brown skin, short tightly curled black hair, brown eyes, small scar above right eyebrow"; expression_and_demeanor: "calm, determined"; outfit_variants: "everyday: faded dark-brown hoodie, worn blue jeans, black sneakers, brown canvas shoulder bag"
