AI Localization Agent
Turn your coding agent into a localization specialist. Add our MCP server to GitHub Copilot, Cursor, Claude, Codex, or Windsurf and let your agent translate i18n files without dumping unnecessary data to its context. See AI Localization Agent Setup Guide
Your agent gets format-safe translations, persistent terminology, and incremental updates that stay reliable across sessions.
What changes with MCP
Instead of improvising translations in context, the agent can hand localization off to a purpose-built engine.
- Persistent glossaries keep product terms consistent across every file and every future run.
- Custom instructions lock in tone, market preferences, and brand wording.
- Server-side format checks protect keys, placeholders, and file structure before results come back.
- Incremental translation skips unchanged strings, saving quota and preserving approved translations.
Why AI Localization?
- With AI, you can automate localization, reducing manual effort and speeding up the process.
- AI is code-aware and preserves i18n file formats, keeping keys intact and correctly handling placeholders.
- With AI, you can translate less common languages where human translators may be scarce.
- AI understands context, reducing mistakes in ambiguous phrases compared to traditional machine translation.
- With AI, you can translate large volumes of text in minutes, accelerating global releases. It also tailors translations to regional variants, selecting vocabulary that matches local cultural context.
- AI ensures uniform translations across files, avoiding inconsistencies in terminology and following predefined style guides.

Localization on your terms — a private, dedicated instance
When your unreleased strings can't go to a shared service, we run the same AI localization engine as a private, single-tenant instance we deploy and manage for you — in your cloud region, with your data inside your own infrastructure. Enterprise control without hiring a localization team.
- Your data stays yours — an isolated instance in your region, with the database in your own infrastructure.
- Bring your own AI model and keys, kept under your security and compliance controls.
- Format checks built for your exact i18n files, so AI translations are double-checked and can't break your production build.
- Predictable flat pricing with no per-character limits — replacing the cost of an in-house localization team and toolchain.
