Also known as: Brand persona, Writing persona, Voice profile
The persona service is Rankmio's answer to the "all AI texts sound the same" problem. For each project, brand documents are loaded into a library — pitch decks, brand guidelines, sample articles, style guides. From these, the service extracts the essential brand voice characteristics: tone, favourite phrases, typical patterns of argument, specialist vocabulary. In every AI generation this brand context is passed along as a persona instruction, so that the output remains consistent in the brand's voice.
Rule of thumb: better 5 very typical documents than 50 poor ones. Quality over quantity.
An important point of architecture: the persona service supplies the voice, the brief instructions supply the structure. The two complement each other. A brief says: "Write a 1,500-word article on X with H2 question-and-answer headings." The persona adds: "in our typical tone — matter-of-fact, direct, with examples from the B2B SaaS context, without buzzwords, with clear recommended actions at the end."
Example: A marketing agency looks after 6 clients in different industries. Each client has its own library with 4–6 brand documents. AI-generated articles sound consistently different for each client: the SaaS client concise and sober, the B2C lifestyle brand playful and emotional, the B2B consultancy authoritative and fact-based. The classic advantage: editors do not have to manually "bring every AI text into the client's tone" — it already comes out of the generator with the right sound.
