Character craft
An AI influencer character bible: the reusable template
Use this character bible template to keep your AI influencer’s appearance, voice, world and publishing decisions consistent across a growing content library.
In this guide
A character bible keeps an AI influencer recognizable when you change scenes, add collaborators or return to a project weeks later. It should answer practical production questions in a page or two, with links to approved references.
Write the core premise in one sentence
Describe the character’s recurring point of view, not their entire fictional life. “Mallow treats ordinary errands as formal occasions” gives a writer and editor something to use. A long biography about a childhood that never appears in the content may not.
Add a short audience promise: what someone gets by following. That might be visual comedy, unusual styling or a recurring fictional world. Keep the promise stable enough that a new idea can be judged against it.
Use this working template
| Field | What to record |
|---|---|
| Premise | One recurring tension or perspective |
| Identity constants | Face, silhouette, proportions, signature details |
| Flexible styling | Outfits, props and locations that can change |
| Voice | Sentence length, humor, vocabulary and examples |
| World rules | What this fictional character can plausibly do |
| Commercial boundaries | Product categories, prohibited claims and disclosure approach |
| Approved assets | Versioned references, logos, audio and permissions |
| Review owner | Who approves identity, facts and the final post |
Make voice concrete with examples
“Witty and confident” is too broad to guide a caption. Write three lines that fit and three that do not. Mallow might say, “The invitation said casual. I chose not to read it.” A breathless list of superlatives might feel wrong for the same character.
Separate the voice guide from factual answers. A playful character can still give an exact product name, acknowledge uncertainty and hand a question to the team. Personality should never invent shipping promises, prices or a personal product experience.
Define the limits of the fictional world
Decide whether the character talks, uses human hands, changes scale or interacts with real people. These choices affect references and editing. If Marble’s hands are consistently stylized paws, a sudden human hand in a product close-up is a continuity error even when the frame looks polished.
Record exceptions deliberately. A surreal dream sequence can break a world rule, but it should read as an intentional story choice. Otherwise, production errors slowly become an inconsistent identity.
Add a change log that someone will maintain
Keep changes short: date, decision, reason and affected assets. “Changed default glasses to cream frames; new front and profile references approved” is enough. Link the old version so an editor can finish an existing project without mixing references.
Review the bible after the first few posts, then when a major identity or commercial decision changes. Do not rewrite it after every weak result. A useful document reduces repeated decisions; it should not become another source of production work.
Test whether another person can use it
Give a collaborator the bible and one scene idea. Ask them to choose a reference, draft a caption and identify what needs approval. If their choices surprise you, clarify the missing rule with an example. This is more informative than adding another page of adjectives.
Use the bible alongside a reference sheet and a final video checklist. The bible defines the character; the checklist catches what the actual output got wrong.
