Brand voice & content guardrails builder

Fill in your brand name, voice traits, words you use and never use, claims rules, disclosure stance and who approves what. The tool builds four documents from fixed templates: a brand voice guide (with a block to paste into AI tools), an AI content policy, disclosure rules and a risk-tiered approval workflow. Then paste any ad, post or email: the checker runs deterministic rules — banned words, required disclosure, unsupported superlatives and claims such as 'best', 'guaranteed' or '#1', figures without a source, reading level, length and exclamation density — and gives a pass/warn/fail list and a score. No AI writes the documents; AI only explains a result.

Example data. Example brand: replace the name, words and roles with your own.

# Northwind Coffee brand voice guide (for people and AI tools)

This guide tells writers, designers, agencies and AI tools how Northwind Coffee sounds. Paste the "Instructions for AI tools" block into the system prompt or brand settings of any AI writing tool you approve.

## Our voice
- **warm**
- **plain-spoken**
- **curious**
- **quietly confident**

## Words we use
- fresh
- simple
- together
- craft
- you

## Words we never use
- synergy
- revolutionary
- game-changing

## Claims
- Taste and quality claims are opinion ('we think'), never ranked ('#1', 'best') without a named source.
- Price claims need a date and the comparison basis.
- Sustainability claims need the certificate or data on file before publishing.
- No health claims about coffee.

## Readability
- Aim for a US reading grade of 8 or lower: short sentences, everyday words.
- One exclamation mark at most per piece unless the format calls for more.
