What is a tone profile?
A tone profile is a structured representation of how you write. Not a list of adjectives. A measurable set of patterns extracted from your actual writing.
A tone profile is a structured model of your writing patterns. It captures how you construct sentences, which words you reach for, how you punctuate, and how you organize ideas.
It is not a description like "casual and direct." It is a set of measurements: your sentence length distribution, your vocabulary organized by frequency (words you use constantly vs. rarely), your punctuation habits, your paragraph structure, and representative excerpts from your real writing.
What goes into one
Sentence rhythm. Not just "short sentences" but the ratio. Maybe 55% short, 30% medium, 15% long, with occasional fragments. This ratio creates your cadence.
Vocabulary tiers. Your words in three frequency buckets: core register (used constantly, free to use anywhere), signature phrases (used regularly, a few per piece), and rare emphasis (used once every few thousand words, only when the moment earns it). Plus a "never uses" list.
Punctuation profile. Which punctuation does the heavy lifting. Commas, colons, parentheticals, ellipses, or their absence.
Structural habits. How you open sections, how you close them, paragraph length, use of lists or rhetorical questions.
Representative excerpts. Actual passages from your writing, organized by type: default rhythm, openings, transitions, closings, rare emphasis. These are what the AI pattern-matches against when rewriting.
How it differs from a "tone setting"
Most AI tools offer tone settings: professional, casual, friendly, authoritative. These are labels, not profiles. "Professional" means something different for every person. Your professional voice is different from your colleague's professional voice. A tone setting cannot capture that difference.
A tone profile is specific to you. It is built from your data. Two people with profiles labeled "professional" will produce entirely different output because their patterns are different.
How Yourtone builds one
You upload writing samples. The system analyzes them and extracts the patterns into a structured profile. Each sample is classified into one of 14 style categories and builds the corresponding voice slot.
The profile strengthens over time. Every rewrite you approve feeds back into it. After a few dozen approvals, the system has a high-confidence model of your patterns in that register.
The profile is what makes Yourtone different from generic rewriting tools. It is the engine. Every rewrite draws from it. The output sounds like you because the engine was built from you.
