Frequently Asked Questions

How is this different from DeepL or Google Translate?

This tool uses frontier AI models like GPT-4o and Gemini 2.5 Flash that understand context and nuance far better than traditional machine translation. There are no character limits, no signup required, and your text stays private — it goes directly from your browser to the AI provider. You control the cost by bringing your own API key.

Is this free?

Yes, the tool itself is completely free. You just need an API key from OpenAI or Google. A typical translation costs $0.001–$0.01 depending on the model and text length — far cheaper than any translation subscription service like DeepL Pro.

Which languages are supported?

20 languages: English, Spanish, French, German, Chinese (Simplified), Chinese (Traditional), Japanese, Korean, Portuguese, Italian, Russian, Arabic, Hindi, Dutch, Polish, Turkish, Swedish, Vietnamese, Thai, and Indonesian. Auto-detect is available for the source language.

Is my text private?

Yes. Everything runs in your browser. Your text goes directly from your browser to the OpenAI or Google API — it never touches our servers. There is no backend. You can view the source code to verify.

Which model is best for translation?

GPT-4.1 Nano or Gemini 2.0 Flash for fast, cheap translations. GPT-4o for the highest quality, especially with nuanced or literary text. Gemini 2.5 Flash offers an excellent balance of quality and cost for everyday translation.
