Translate and validate your i18n JSON with AI.

Poliglotify uses AI to transform i18n JSON files into clean, translated versions for multiple languages — without breaking keys, placeholders, or your deploy pipeline.

Built for SaaS teams, indie hackers, and agencies tired of copy-pasting strings into random tools.

From JSON to localized bundle in 3 steps

No custom scripts, no spreadsheets, no broken builds.

Step 1

Upload or paste your i18n JSON

Bring your translation files exactly as they are. We keep the structure intact.

Step 2

Choose target languages

Generate localized JSON files (for example fr, de, es) with consistent tone.

Step 3

Receive translation by email

We validate keys, placeholders, and JSON syntax and send a ready-to-use file.

Built for developer workflows

Poliglotify focuses on one thing: making i18n JSON translation simple and safe.

Structure-preserving translations

Your keys are not touched. Only values change, keeping deployments predictable.

Placeholder and interpolation care

Variables like {name} or %s remain exactly where they should be.

Consistent tone across languages

Use a single source of truth and have consistent tone across all languages.

Powered by modern AI models

Frequently asked questions

Is Poliglotify free right now?

During early access, we offer generous free usage while we learn from real use cases. Pricing may change in the future, but you'll always be notified in advance.

What languages are supported?

We currently support major languages like English, French, Spanish, German, Italian, Portuguese, and others. New languages are added based on demand from early access users.

Can translations contain errors?

Yes — translations are AI-generated. They're typically high quality, but may contain inaccuracies, tone differences, or minor context issues. Always review before pushing to production.

Does it work with my framework?

If your app uses JSON for localization (Next.js, React, Vue, Node backends, etc.), Poliglotify works. We don't enforce any specific library or runtime.
