Open-source tools for developers. Studio workflows for teams.

Govern the content your AI ships into code.

Contentrain turns hardcoded UI copy, docs, and structured content into a Git-native system that AI agents can safely operate. Start locally with MCP, CLI, and SDK packages; add Studio when teams need review, roles, media, and delivery.

The Problem

Product content was already scattered. AI makes it spread faster.

UI copy, docs, and locale strings have lived across components and files for years. AI agents now create and change that content faster, multiplying the same governance problem.

Hard to review
Hard to audit
Hard to localize
Hard to scale

Scattered component, documentation, and locale files connected by fragmented workflows and warning markers.

One governed content system

Agent generates. Human approves. Git records every change.

The same typed content models power local developer tools and Studio workflows. Start in the repository, then add editing, roles, and review without moving content to a separate source of truth.

Contentrain AI packages

MCP, CLI, SDK, types, rules, and skills for local, framework-agnostic content work with AI coding agents.

From hardcoded copy to governed content

Start with the mess already in the codebase.

Most teams do not wake up needing a new content platform. They wake up with hardcoded copy, no reliable translation path, and AI agents editing strings directly in source files.

Scan

Find user-visible strings with project context.

Create models and content files in Git.

Repeatable content infrastructure

Agencies can start each client with the same Git-native content workflow, template driven models, Studio review and delivery surface.

Govern the content your AI ships

Turn AI-generated UI copy, docs, and locale strings into structured content you can review and reuse.

Let non-developers edit without losing Git control

Editors work in Studio. Developers keep branches, diffs, validation, and source-of-truth control.

One content contract for web, mobile and APIs

Deliver structured content to web, docs, mobile, and APIs from the same Git-backed system.

Control by design

Governance is part of the workflow. Not an add-on.

Content stays in Git. Models constrain its structure. Bounded tools, validation, branches, diffs, and review keep changes inspectable before they reach production.
