1. Define the audience job before the face
Decide why someone would follow this account if the visuals were removed. A useful answer is specific: quick strength training for busy parents, modest fashion combinations for hot climates, or practical city guides for first-time solo travellers.
Write one sentence in this form: “This account helps [audience] achieve [outcome] through [repeatable format].”That sentence is the editorial filter for every character and content decision that follows.
2. Write a character brief that can survive 100 posts
Define the fictional character’s niche, worldview, personality, voice, boundaries and visual direction. Use details that affect future decisions. “Optimistic” is vague; “encouraging without shame or transformation hype” is usable editorial direction.
Include these six fields
- Audience and the promise made to them.
- Three to five personality rules and voice examples.
- A visual aesthetic, signature environments and wardrobe logic.
- Topics the character covers—and topics it will not cover.
- The account’s transparent synthetic-media disclosure.
- A short origin and motivation that support future stories.
Use the free AI influencer prompt generator to turn these choices into a working brief and starter scenes.
3. Create one canonical visual identity
Generate several candidates from the same brief, then choose one fictional person as the canonical identity. Evaluate more than attractiveness: look for a distinctive but reusable face, believable anatomy, compatibility with the niche and enough range for different expressions and settings.
Save the chosen identity in an identity-preserving workflow. A detailed text prompt can guide appearance, but prompt repetition alone does not reliably preserve the exact same person across a long-running feed.
4. Run a consistency test before publishing
Create a small test matrix before you build the launch grid. Keep the identity fixed and deliberately vary the conditions:
- Close portrait, waist-up frame and full-body composition.
- Indoor, outdoor, daytime and low-light environments.
- Neutral, joyful, focused and candid expressions.
- Three distinct outfits that still fit one wardrobe system.
- A single image and a connected three-image carousel.
Review facial proportions, age, skin tone, body shape and signature details across the set. If the person is not recognisable without the caption, fix the identity workflow before scaling production.
5. Build a content system, not a folder of portraits
Choose three recurring content pillars: one that teaches, one that reveals character, and one that creates a recurring story or community ritual. For each pillar, define a format, the audience takeaway and a visual pattern.
Produce in small batches. A useful first batch is nine posts: two posts from each pillar, one account introduction, one transparent “how this synthetic character is made” post and one experimental format. This is enough to test the system without pretending you already know what will work.
6. Publish with clear synthetic-media and sponsorship disclosure
Treat disclosure as part of the creative system, not legal text hidden in a profile. Meta says it applies “AI info” labels when it detects relevant industry signals or when a person discloses AI-generated content. Review the current platform rules before publishing because policies and interfaces change.
Sponsorship disclosure is a separate obligation. The U.S. Federal Trade Commission says material connections should be disclosed clearly and conspicuously with the endorsement itself; a profile-only disclosure may be missed. Rules vary by market, so obtain professional guidance for the jurisdictions you target.

7. Measure the account promise, then improve the system
Track more than follower count. Record saves, shares, meaningful replies, profile visits and the formats that produce repeat engagement. Compare results by content pillar and creative format so you can decide what to continue, change or stop.
Review character consistency separately from content performance. A technically consistent face cannot rescue weak ideas, and a strong idea should not be discarded because one generation needs revision.
What should you do next?
Build the brief first. Then create and test the persistent visual identity before committing to a large content calendar. Inflova’s current beta supports that foundation: fictional identity creation, character-consistent images, coordinated carousel sets and a downloadable asset library.
