AI localization workflow

Collaborative Localization for the AI Era

Translation JSON should be generated output, not your collaboration layer.

Editing Translation JSON Directly

No shared review workflow
Translators blocked from the process
Copy changes bottleneck through engineers
Translations drift across languages
JSON merge conflicts
Duplicate or inconsistent strings

Shared Localization Workflow

AI agents add source strings through MCP
Team reviews and verifies translations
PMs edit copy without waiting on engineers
Translators work in the dashboard
Generated translation JSON stays synced
Developers keep using their existing i18n library

One command setup

Quick start with the CLI

Run the init command from your app repository to create your i18nexus account and first project, detect your i18n library, set up languages and namespaces, and import existing translations.

It can also configure the MCP for AI coding agents and add i18nexus listen so local translation files stay synced while you build.

i18nexus becomes the source of truthLocal JSON generates from shared workspace

npx i18nexus-cli init

Create the workflow once, then manage source strings in i18nexus instead of editing generated translation JSON by hand.

Change the checkout CTA banner to say, "Your payment is secure. Complete your order when you're ready."

Found the checkout banner in CheckoutPayment.jsx

i18nexus MCP

add_string({
  key: "checkout.payNow",
  value: "Your payment is secure. Complete your order when you're ready.",
  description: "Context: Primary CTA banner on the checkout payment step."
})

Saved source string with AI translation context

Codex

I updated the banner copy in the app and saved the new string in i18nexus with context from the checkout payment step. i18nexus automatically translated it so your team can review everything in the dashboard.

AI Agent Workflow

AI Agent MCP Workflow

The i18nexus MCP gives AI coding agents a direct line to your i18nexus project, so copy changes become source strings as the feature is being built. Each string includes context for better AI translation, and translation JSON files stay generated, never edited by hand.

After evaluating a few alternatives, we found i18nexus to work the way we thought the ideal translation service should. The automated translations are very good out of the box, the web UI is intuitive and easy for non-technical contributors to use, and the API makes integrations with CI/CD trivial.
