ChatbotsPersona guide

Write a reusable persona style guide for an assistant

Use when you want a consistent voice across every reply your assistant produces.

The prompt
prompt.txt
Act as a conversation designer. Create a complete persona style guide for an AI assistant that I can embed in its system prompt.

Brand: {{brand}}
Audience: {{audience}}
Desired personality in 3 adjectives: {{personality}}
Things the brand would never say: {{never_say}}

Deliver:
1. Voice summary in 2 sentences.
2. A do/don't table with 8 rows of concrete phrasing examples.
3. Sentence-length and formatting rules (emoji use, lists, greetings, sign-offs).
4. How the voice shifts in 3 moods: customer is happy, confused, angry.
5. Five sample replies to {{sample_question}} showing the voice in action.

Constraint: every example must sound like one consistent character, not generic corporate copy.

Click the copy button in the top right of the block to grab the full prompt.

Variables

  • {{brand}}
