A Brand Voice That Survives Volume

What it is for

Voice defined loosely holds for about ten pieces. This is how to define it so the fiftieth still sounds like the first: concrete rules, named things to avoid, and examples of the near-misses rather than the obvious failures.

The skill Copy

Voice defined as adjectives does not survive volume. "Friendly, professional,
approachable" produces a different output every time because it constrains
nothing.

Define it as decisions instead:

- **Person and number.** "We" or "I"? Do you address the reader as "you"?
- **Sentence length ceiling.** An actual number. "No sentence over 22 words."
- **Two words you always use and two you never use.** Not a long list — a long
  list is ignored. Two of each is remembered.
- **The joke policy.** None, one per piece, or freely. Ambiguity here is what
  makes a set feel inconsistent.
- **How you refer to the competition.** By name, as "other tools", or not at all.
- **One paragraph you consider perfect**, pasted in full. This does more than
  every rule above combined.

Test the definition before using it: generate the same brief three times and
read the three openings. If they could be from three different companies, the
definition is still adjectives.

How to install it Copy

1. Open the tool and start a new conversation, project or template.
2. Paste the text below wherever the tool keeps standing instructions
   — usually called system prompt, instructions, or persona.
3. Save it so it applies to every run rather than a single message.
