Decide who the brand is
before anyone writes for it.

A brand personality framework is a structured definition of the human characteristics a brand expresses, and the rules that turn those characteristics into how it writes, looks and behaves. It usually includes three to five core traits, a brand archetype, personality sliders that set the degree of each trait, a we-are and we-are-not list, voice and tone rules, visual cues and examples. Its purpose is consistency: every person and partner making the brand expresses the same personality.

Start from evidence rather than aspiration: customer interviews and reviews, the founder's story, what employees believe, and how competitors present themselves. Place the brand on personality sliders such as formal to casual and serious to playful, compare it with competitors on the same sliders, then choose three to five traits and an archetype that are true and distinct. Define each trait in a sentence, pair it with the failure it must avoid, and test it by writing real examples.

Brand personality sliders are spectrums between two opposite qualities, such as formal and casual, serious and playful, classic and modern, or accessible and exclusive, on which a team places the brand. They are useful because most brands share the same positive traits, and what makes a brand distinct is the degree: slightly playful and very playful produce different writing and design. Placing competitors on the same sliders shows whether the brand's position is genuinely different.

Jennifer Aaker's framework, published in 1997, groups brand personality into five dimensions: sincerity, such as honest and wholesome; excitement, such as daring and imaginative; competence, such as reliable and successful; sophistication, such as upper class and charming; and ruggedness, such as outdoorsy and tough. It remains a widely used starting vocabulary, although most brands then define more specific traits of their own within one or two of the dimensions.

The twelve archetypes most often used in branding, popularised by Margaret Mark and Carol Pearson in The Hero and the Outlaw, are the Innocent, Everyman, Hero, Outlaw, Explorer, Creator, Ruler, Magician, Lover, Caregiver, Jester and Sage. Each describes a recognisable character with its own motivations and voice. Brands usually choose one primary archetype and sometimes a secondary one, and use it as shorthand rather than as a rigid script.

Brand personality is who the brand is: its character traits and archetype. Brand voice is how that personality sounds in words, expressed through vocabulary, sentence style and rhythm, and adapted into tone for different situations. Personality also drives visual identity and behaviour, not only writing. A framework usually defines the personality first and derives voice rules from it, because a voice written without a personality behind it tends to become a list of style preferences.

Consider how differently familiar categories feel. An outdoor brand built on ruggedness and the Explorer archetype writes about places and endurance with plain, confident language. A premium fashion house leaning on sophistication writes sparingly and lets imagery carry the mood. A challenger bank using the Outlaw or Jester archetype might use humour about the frustrations of traditional banking. The useful exercise is to describe competitors in your own category this way and find the position none of them holds.

Three to five is the practical range. Fewer than three rarely gives writers and designers enough to work with, and more than five makes the traits blur into a general description of a pleasant company that nobody can apply. Each trait should change a decision, such as which photograph to choose or how to reply to a complaint. If removing a trait would not change any real piece of work, it does not belong in the framework.

Make it easy to apply and hard to ignore. Express every trait through examples, such as a headline, a caption and a customer reply, because people copy examples rather than adjectives. Share the framework by link with agencies, freelancers and new hires, reference it in every campaign brief, and review a sample of real output against the sliders every quarter. A framework that lives only in a launch presentation is forgotten within months.

Yes, with research, drafting and testing, but it should not decide who the brand is. In Storyflow the AI reads the interviews, reviews and notes on the board, proposes traits and an archetype for the team to challenge, describes real competitors' tone for comparison, and writes examples in each trait so weak traits show up quickly. Choosing the personality is a strategic decision for the founders and brand team, and the AI's drafts are where that argument starts.

Not yet. Storyflow is paid-only during early access, with plans from $7.99 a month billed annually ($9.99 monthly). A free plan launches before the end of 2026, and anyone a paid member invites to a board joins free. Inviting the brand team into the workshop is not a cost decision, and agencies and freelancers reading the framework through a view-only link never need an account.
