A brand guidelines template for an AI influencer has to govern more than colors and fonts. It must define who the fictional persona is, what they may claim, how the identity stays recognizable, when sponsorship is disclosed, which source assets are approved, and who can authorize a change. Without those rules, every new prompt quietly becomes a new brand.

Create an On-Brand AI Influencer with APOB

This guide provides copyable influencer brand guidelines for one visibly adult fictional persona. APOB AI prepared it on August 27, 2026 as educational guidance, not legal advice, and it invents no completed test result. US teams can use the linked Federal Trade Commission material as a baseline; teams operating elsewhere need local review. Build the persona in APOB’s AI Influencer Generator, then test the rules on three unpublished posts before scaling.

Start with the brand and audience contract

Visual styling comes after the business contract. Complete this first page with one accountable owner. Every field must be short enough that a reviewer can use it during production.

Audience

Write one primary audience, one context, and one unmet need. Avoid “everyone interested in lifestyle.” A useful entry is: “First-time apartment renters in US cities who want low-cost, reversible decor ideas.” Add age restrictions, excluded markets, language, accessibility needs, and any sensitive contexts.

Fill in: Primary audience ___; location/language ___; situation ___; need ___; excluded audience ___; accessibility requirement ___.

Add two audience counterexamples. “A college student seeking budget decor” may fit; “a homeowner seeking structural renovation advice” may not. Counterexamples help writers reject adjacent topics that sound relevant but push the fictional persona beyond the approved expertise.

Brand promise

Define what followers can reliably expect and what evidence supports it. A promise should guide content choices, not act as an unverified superlative. Fictional example: “Mara turns small-space design principles into practical weekend experiments and labels sponsored products clearly.”

Fill in: We help ___ do ___ by ___; proof source ___; promise owner ___; review date ___.

Write one approved proof pattern and one prohibited extension. If the evidence supports “shows three reversible storage ideas,” it does not support “will double your storage.” This pairing gives reviewers something concrete to compare when a model makes language more promotional.

Content boundaries

List subjects the persona covers, subjects requiring expert review, and subjects that are prohibited. Include financial, medical, legal, safety, body-image, political, or age-sensitive restrictions where relevant. Add seven prohibited phrases such as “guaranteed,” “risk-free,” or an unsupported “best.”

This boundary should feed the approved planning layer. Map each allowed subject into content pillars for AI influencers so a calendar cannot schedule an off-brand claim simply because it is trending.

Success signal

Choose one outcome for the next thirty days: qualified saves, completed views, approved landing-page visits, or another measurable action. Add a guardrail such as complaint rate or correction count. Avoid declaring success from vanity reach alone.

Fill in: Desired action ___; measurement source ___; review window ___; minimum signal ___; safety/quality guardrail ___; decision owner ___.

Lock the AI influencer persona

The persona record is the identity contract. Version it before generating campaign assets.

Persona facts

Record display name, fictional status, visible adult age range, pronouns, location, expertise boundary, backstory, values, recurring interests, and facts that must never change. Do not borrow a real person’s likeness or biography without authorization.

Fictional example: “Mara Vale; fictional; appears 28–32; she/her; renter in Chicago; experienced home-organization creator, not an architect; values affordability and reversible changes.” Assign persona-v1.0 and an approval date.

Voice and vocabulary

Describe sentence length, rhythm, humor, reading level, preferred terms, prohibited terms, pronunciation, and platform variation. Include three approved sample lines and three “never say” lines. Voice is not a list of adjectives; it is evidence a reviewer can compare.

Keep: direct opening, one concrete example, short disclosure. Avoid: invented personal memories, absolute advice, and fake urgency. Store approved pronunciation for product and place names.

Claim boundaries

Create a claims register with statement, evidence URL, owner, valid-through date, allowed paraphrases, and prohibited extension. If evidence expires or the statement changes, remove it from prompt blocks and scheduled content. An AI-generated caption cannot create permission to publish a claim.

Use human review for health, safety, performance, price, environmental, or comparative statements. Stop production when the generator adds a new benefit, number, testimonial, or credential.

Disclosure rules

The FTC’s Disclosures 101 for Social Media Influencers says material connections should be disclosed clearly, in a place people are likely to notice, and in the content when appropriate. The guide also addresses video disclosures and truthful endorsement statements. Treat this as US-specific guidance and have counsel or a qualified local reviewer adapt it.

Fill in: Material connection types ___; approved disclosure text ___; visual placement ___; spoken placement ___; language versions ___; reviewer ___; local-market exception ___.

Test disclosure in the actual layout before approval. Check the first screen, caption truncation, audio, contrast, duration, and each localized version. A disclosure stored in the guideline but hidden behind “more,” cropped from a vertical video, or left untranslated is not an effective production control.

Build the visual identity system

AI influencer branding needs a controlled reference set because a hex code cannot preserve a face, wardrobe, or camera language.

Reference set

Create an owned master board with front, three-quarter, profile, full-body, and expression views. Add lighting and skin-tone references, hair, body proportions, signature accessories, and forbidden variations. Each image needs an asset ID, origin, rights evidence, approved use, and version.

APOB’s persona-centered workflow is useful here: approved identity references can remain tied to a reusable character rather than being reassembled from unrelated assets for every post. That reduces handoff drift, though every output still needs review.

Color and type

Record primary, secondary, and neutral colors with contrast-approved combinations. Specify headline, body, caption, and on-image text roles. Add minimum size, maximum line count, and mobile readability. Provide a monochrome fallback and a do-not-use list.

Keep example: deep navy background, warm ivory body text, coral accent only for CTA. Avoid: coral body paragraphs, low-contrast text on generated imagery, and unapproved decorative fonts.

Wardrobe and props

Define three approved wardrobe families, recurring props, product-handling rules, jewelry, seasonal variations, logo policy, and cultural restrictions. Describe colors and silhouettes, not vague “premium” style. Every third-party product needs rights and claim review.

For ad-focused execution, connect the approved persona and props to the underlinked Character AI Ads workflow. The link is an execution route; it does not replace the brand guide or rights review.

Shot and crop rules

Specify portrait distance, eye line, camera height, lens feel, background depth, negative space, motion limits, safe areas, and permitted aspect ratios. Include 9:16, 1:1, and 16:9 crop examples using the same owned reference. Mark which body parts and products cannot be cropped.

Create a contact sheet after every batch. Reject frames with identity drift, broken hands, changed product geometry, unreadable text, or unsafe cropping. Do not select only the strongest frame and hide the failure rate.

For each approved crop, mark the safe area for face, hands, product, disclosure, captions, and CTA. Review it at 390px, 768px, and 1440px widths when the asset will appear on the web. Keep a failure example beside every rule so production teams can recognize the boundary quickly.

Create prompt and production guardrails

Turn the brand identity guidelines into reusable production inputs. A prompt is a versioned assembly, not a fresh improvisation.

Prompt blocks

Use this skeleton:

Keep variable details separate from immutable persona facts. If a campaign requests a conflicting identity fact, return it to the approval owner rather than forcing the prompt to reconcile it.

Negative constraints

List prohibited identity changes, claims, logos, ages, products, gestures, environments, text, and sensitive themes. Write observable constraints: “no visible third-party logos” is reviewable; “make it safe” is not. Keep the list concise enough to audit.

No model guarantees perfect consistency. The negative block is a review contract, not a technical guarantee. Two failed full attempts trigger a human edit, simplified scene, or revised brief.

Asset library

For each asset, store ID, name, owner, rights evidence, source file, checksum, locale, status, approved uses, prohibited uses, and retirement date. Separate master references from campaign outputs. Preserve failures in a review folder so future model changes can be retested with the same inputs.

Versioning

Use semantic versions: major for identity or promise changes, minor for approved visual or voice expansion, patch for corrections. Every generation job records persona version, prompt version, model, date, reviewer, and final asset ID. Never overwrite a master reference.

Schedule approved posts only after the version is locked. The AI influencer social media calendar can carry the version and approval status into execution.

Do a monthly version audit. Select three published assets at random and trace each one back to persona version, prompt version, claim evidence, rights record, and final approver. If any link is missing, stop new production and repair the asset history before adding more variations.

Add disclosure, review, and change control

The final section turns the brand style guide template into a publishing gate.

FTC disclosure checkpoint

For US-targeted sponsored content, verify material connection, disclosure wording, prominence, placement, language, and spoken disclosure when needed. The FTC’s Endorsement Guides Q&A explains advertiser and endorser responsibilities. This article does not determine legal compliance; name the qualified reviewer responsible for the market.

Visual/voice QA

Compare face, hair, body, wardrobe, palette, typography, framing, product, pronunciation, tone, captions, and audio against the approved version. Review at normal speed and frame-by-frame at transitions. Attach evidence for every rejection.

Claims evidence

Match each factual or comparative statement to an active claim ID and source. Reject unsupported numbers, invented testimonials, unapproved personal experience, and altered disclaimers. Confirm that translation preserves the same limitation and disclosure.

Change log

Record date, requester, old value, new value, reason, affected assets, approver, and rollback plan. A persona change is not complete until prompt blocks, reference assets, scheduled posts, and locale guidance are updated.

Rehearse one rollback before launching the persona. Change a minor wardrobe rule in a test branch, trace the affected prompt and three sample posts, then restore the prior version. The exercise proves that owners can reverse a bad update without deleting history. Keep old references read-only rather than replacing them.

For localization, store approved translations of the persona name, disclosure, CTA, prohibited claims, pronunciation, and culturally sensitive examples. Require a native-language reviewer. Back-translation can reveal omissions, but it does not replace review of tone, legal meaning, and on-screen fit.

Copyable one-page checklist: audience and action defined; promise sourced; boundaries approved; fictional adult facts locked; voice examples present; claims register current; disclosure localized; master references owned; colors/type/crops documented; prompt and negative blocks versioned; asset rights recorded; two-attempt limit set; visual/voice QA passed; approver named; change log updated. Run it on three unpublished posts. The decision rule is pass only when all three clear the checklist; if one fails, repair the system before publishing the series.

Sign the checklist with guideline version and date, then archive it beside the three sample outputs. Recheck on November 27, 2026 or sooner when the persona, sponsor relationship, market, product claim, platform format, or disclosure guidance changes.
