The Take

Extracts user-facing strings from JS/TS, templates, Markdown, and many backend formats, then runs each snippet through OpenAI or Anthropic to score tone against selectable voice templates (Professional/Casual/Technical) and report file+line hits. BYO API key and optional score-sharing keeps raw text local by default — smart for privacy — though I'd like to see CI hooks, rule customization, and threshold tuning to tame noisy LLM judgments.

Post Description

hey,

built a cli that scans your codebase for off-brand product copy. think eslint but for your brand voice.

`npx brandlint`

it extracts user-facing strings (jsx text, error messages, placeholders, i18n), checks them against a voice template (professional, casual, technical), and reports issues with file and line number.

works with anthropic or openai keys. nothing leaves your machine except the score summary if you choose to share it :)

supports ts/tsx, vue, svelte, html, json, yaml, markdown, php, python, and more.

would love feedback. what brand voice rules do you usually enforce in your products, if any?
