Brand voice profile

Choose how your brand should sound — the language and country it writes in, the rules it writes by, the words it never uses — and get a plain-text voice profile to paste above a request to any writing tool, with one sample sentence written to it. It is the same profile, rendered by the same code, as the Voice panel in the Playground.

Pick a language and country, then as much of the rest as you want. Everything but the language and country is optional, and a part you leave empty is simply left out of the profile.

Profile name (optional — up to 80 characters) Language and country — required. Every rule in the profile is written in this language, in this country's version of it.

Voice attributes: pick the ones that describe how you want to sound. Each one you pick is written into the profile word for word.

Says the point first — Put the conclusion in the first sentence. No warm-up paragraph, no restating the question. Short sentences — Keep most sentences under 20 words and let none run past 35. One idea per sentence. Plain words over jargon — Use the word a reader would use out loud. If a term of art is unavoidable, define it in the same sentence, once. Every claim carries its evidence — Attach the source, the measurement or the worked example to the claim itself, in the same paragraph. If there is none, write that the claim is an opinion. Leads with the number — Where a number exists, give it before the adjective: the figure, its unit, and what it was measured on. Never a comparative with no baseline. Names the obvious objection — State the strongest objection a skeptical reader has, in their words, before answering it. Do not answer an objection nobody would raise. Refuses hype — No superlatives, no revolutionary, no game-changing, no unlock. Describe what the thing does and let the reader be impressed or not. States its limits as plainly as its claims — Say what the thing does not do, and where it stops working, in the same voice as the benefits — not in a caveat at the end. Argues against the common view — Open by naming the advice everyone repeats, then say plainly why it is wrong here, with the evidence for the disagreement. Opens with one specific scene — Begin with a single concrete moment: one person, one place, one thing that happened. Draw the general point out of it afterwards, never before. Talks to one reader — Write to one person as you. No we the company, no dear customers, no audience addressed in the plural. Ends with something to do — Close with one action the reader can take today, small enough to finish in an afternoon. Who it is written for (optional — up to 600 characters) Reading level (optional) Words and phrases never to use, one per line (optional — up to 40, each up to 300 characters) Preferred structures, one per line (optional — up to 40, each up to 300 characters) Example sentences in this voice, one per line (optional — up to 40, each up to 300 characters) Anything else that matters (optional — up to 600 characters)

No account. No AI call. Nothing is uploaded: this runs in your own browser, so what you choose never reaches us to be kept.

What it reads

This turns the choices you made into written instructions about style — the same text the Playground's Voice panel exports — and shows one fixed sample sentence written in your voice and in the other countries that share your language. It reads your choices and nothing else.

Profile name
Language and country — required, and written first, because every rule after it is written in that language

Anything else that matters
How to structure the piece — the same four rules the draft grader grades against, written out in full
What the profile does not do — printed inside the exported text itself, so the tool reading it is told too

What it does not look at

whether anything written to this profile is true: a profile describes style, and a model following every rule in it can still invent a statistic, a quotation or a source
whether text you already have sounds like this voice — it writes the instructions, it does not read or grade a draft
whether a passage was copied from somewhere: nothing here compares any text against any other text
whether the voice suits your readers, your market or your product — it records the choices you made and does not judge them
any language other than English, Spanish or French, because those are the three whose sample sentence it can show you
how a particular writing tool will follow the profile: the text is instructions, and a tool can still ignore some of them

Instructions you keep

The profile is plain text on purpose: it survives a paste into a chat box, an email or a text field that eats formatting, and it keeps working if you never come back here. Nothing in it asks a tool to imitate a real person — the attributes describe a style, by design — and it says in its own last section that it shapes style, not truth.

Holding a draft already? The draft grader marks it against the same four structure rules the profile writes out, and the Coding Guide works to the same standard.
