Brandlint is a powerful command-line interface (CLI) tool designed to enhance product voice consistency by scanning codebases for off-brand UI copy. Similar to ESLint, Brandlint identifies issues such as inconsistent tone, vague messaging, and incorrect casing within user-facing strings. The tool provides detailed feedback, highlighting the exact locations of issues with file and line numbers, ultimately helping to improve the user experience.

Key Features

• Voice Selection: Choose from three distinct voice styles - Professional, Casual, or Technical. Each style guides the tone and messaging aimed at users.
• Comprehensive Scanning: Brandlint intelligently extracts user-facing strings from various file types and frameworks, ensuring thorough coverage of your codebase. It scans JavaScript, TypeScript, HTML, templates, and more, ignoring unnecessary directories such as node_modules and dist.
• AI-Powered Analysis: Leveraging AI, Brandlint analyzes the extracted strings against predefined brand voice guidelines to deliver actionable insights.
• Detailed Reporting: After a scan, Brandlint generates a comprehensive report, including a color-coded score, issue breakdown by file and line, and a summary of top problem categories such as tone and clarity.
• Shareable Score Cards: Users can easily create shareable score cards at brandlint.com/score/<id>, complete with an Open Graph image optimized for social media sharing, and a one-click option to tweet the results.
• Continuous Monitoring: Integrate Brandlint as a GitHub App for automated checks on pull requests, providing inline suggestions to maintain brand voice consistently across all contributors.

Usage Example

To initiate a brand scan, run:

npx brandlint

Set your API key from Anthropic or OpenAI as an environment variable to streamline the scanning process:

export ANTHROPIC_API_KEY=sk-ant-...
# or
export OPENAI_API_KEY=sk-...

Supported File Types

Brandlint supports a wide array of file types, ensuring compatibility with numerous frameworks and languages including:

• JavaScript and TypeScript: .js, .ts, .tsx, and more.
• Frameworks: .vue, .svelte.
• Markup and Templates: .html, .ejs, .hbs, and others.
