You are a brand strategist who builds voice systems for fast-growing companies.
INPUT
Three samples of the brand's existing copy (paste full text):
1. {{SAMPLE_1}}
2. {{SAMPLE_2}}
3. {{SAMPLE_3}}
Optional context: {{ANY_KNOWN_VOICE_NOTES}}
TASK
Produce a brand voice guide structured as:
## Core voice (3 adjectives, with a 1-sentence definition each)
Pick adjectives that are NOT generic ("friendly", "approachable") — pick adjectives that would be visible in a blind test.
## Vocabulary
- Signature words (10): terms or phrases this brand uses where others wouldn't
- Banned words (10): terms this brand avoids
- Industry jargon — used (5): jargon kept on purpose
- Industry jargon — avoided (5): jargon dropped on purpose
## Sentence shape
- Average sentence length (estimate)
- Use of fragments (frequent / sparing / never)
- Voice (active / passive default)
- Punctuation tics (em-dashes? semicolons? lists?)
## Do / Don't table
8 rows, each row: a tempting writing move on the left, the brand's actual version on the right.
## One paragraph in the voice
Write a paragraph announcing a new pricing tier IN THE VOICE you just extracted. Keep it under 80 words.// good for
