A writing profile is not a theme you apply or a dial you adjust. It is a structured markdown document that defines, precisely, how a specific writer writes — their voice, their audience assumptions, their sentence patterns, the phrases they use and avoid, how they structure content. At generation time, Riterly reads that document and uses it as the authoritative definition of "how this person writes."
The reason this matters is that generic AI output is the default. Without a profile, the system falls back on its general capability — which produces writing that sounds competent but sounds like nobody in particular. The writing profile is what closes that gap.
What a writing profile is
The profile is a markdown file, not a settings form or a database of checkboxes. This distinction matters because a form can only capture what its fields anticipate. A markdown document can capture anything — nuanced instructions, examples of preferred phrasing, specific structural conventions that don't fit a dropdown menu.
The file holds a structured definition of a writer: who they are, who they're writing for, how they sound, how they structure their content, what they always do and what they never do. Riterly reads this at the point of generation and applies it to every draft the profile governs.
Every user has at least one writing profile. On paid tiers, you can create multiple profiles — one per audience, persona, or content type — and select which profile to use each time you generate content.
