FAQ

What languages are supported?

46 languages: English, Spanish, Chinese, Arabic, Russian, Japanese, German, French, Hindi, Indonesian, Vietnamese, Thai, Korean, Italian, Turkish, Polish, Dutch, Ukrainian, Bengali, Persian, Hebrew, Swedish, Czech, Romanian, Hungarian, Greek and 20 more.

What file formats are supported?

JSON (React/Vue/Next.js), YAML/.yml (Rails/i18next), Apple .strings (iOS/macOS), GNU .po (Django/WordPress), ARB (Flutter) and Android XML, CSV (Godot/Unity), XLIFF 1.2, Java/Spring .properties, .NET RESX and Mozilla Fluent .ftl. Output ZIP keeps the same format as input.

Can I cancel my subscription?

Yes, anytime — cancel through the Creem customer billing portal (link in your payment receipt), or email [email protected] and we cancel within 24h. No questions asked. Your key stays active until the end of the billing period.

Which plan should I choose?

Small UI files → Free · regular use → Pro · high volume or CI → Scale · pay once → Lifetime.

Is the Lifetime deal really forever?

Yes — pay $79 once and Lifetime never expires, with no subscription. Lifetime is BYOK: connect your own OpenRouter key, with a generous 1,000,000 chars/file limit and no monthly cap, and you pay OpenRouter directly for tokens (usually cents per file). All future features included. Launch price — going up soon.

What is incremental re-translation?

Translate a file, then re-upload a changed version — we only re-translate the lines you added or edited and reuse the rest from your last run (remembered in your browser). It's faster, and you don't pay again for lines that didn't change. Works for JSON.
