Extract, govern, and ship structured content from your codebase.

Contentrain helps teams turn hardcoded UI text, docs, and structured content into a governed, reviewable content layer. Agents can extract, create, translate, and update content, while Contentrain enforces schema, Git review, and portable file output.

Agent extracts or updates content → Contentrain standardizes → Human reviews → Any platform consumes

Try it in 30 seconds

npx contentrain init        # create .contentrain/ workspace
npx contentrain serve       # open the local review UI

That's it. You now have a governed content workspace with models, validation, review branches, and a local UI — no account, no cloud, no proprietary content format.

Start here:

• See the 2-minute demo
• Open the normalize guide
• Read the docs

What Contentrain is for

• Rescuing hardcoded strings from existing apps and turning them into structured, translatable content
• Starting new projects with a real content layer instead of scattering copy across components
• Serving the same content across web, docs, mobile, and backend systems from plain JSON and Markdown in Git

What it is not

• Not an AI writing app
• Not a database-first or dashboard-first CMS replacement for every team
• Not a proprietary content runtime that locks your app to one platform

What it looks like

Before: Hardcoded strings scattered across your codebase — no structure, no translations, no review.

export default function Hero() {
  return (
    <section>
      <h1>Welcome to our platform</h1>
      <p>Start your free trial today</p>
      <button>Get Started</button>
    </section>
  )
}

After: Content lives in .contentrain/, typed and structured. Source files use i18n keys.

export default function Hero() {
  const t = useTranslations()
  return (
    <section>
      <h1>{t('hero.title')}</h1>
      <p>{t('hero.subtitle')}</p>
      <button>{t('hero.cta')}</button>
    </section>
  )
}

// .contentrain/content/marketing/hero/en.json
{
  "cta": "Get Started",
  "subtitle": "Start your free trial today",
  "title": "Welcome to our platform"
}

The normalize flow extracts strings, creates models, and patches your source files — all through reviewable git branches.

This is the strongest entry point into the product:

take the content chaos already in your codebase and turn it into a governed, reviewable content layer.
