Simple to start: sign up, get an API key, and you're translating
Can translate entire websites by just entering a URL

Common questions

Is ModernMT better than SYSTRAN Translate for translating a book?

Yes, if you want the tool to learn your style and corrections as you edit. ModernMT's adaptive engine improves with each fix, making it ideal for long documents. SYSTRAN is faster but won't get smarter as you work.

Can I use ModernMT or SYSTRAN Translate on my phone?

No. Neither tool offers a mobile app. Both are designed for desktop use via web interface or API integration.

Which is cheaper for a freelancer translating 10,000 words a month?

SYSTRAN Translate is likely cheaper if you can get a low-volume plan, but its pricing is not public. ModernMT would cost roughly $15–$30 per month for that volume, which may be too high for a freelancer.

Do these tools work with Google Translate or other CAT tools?

ModernMT integrates with professional CAT tools like Trados and memoQ. SYSTRAN Translate offers an API that can be connected to custom workflows, but it doesn't have direct plug-ins for common CAT tools.

Which tool is more accurate for technical or medical translations?

ModernMT can be more accurate if you upload a high-quality translation memory (TMX) file for your specific field. SYSTRAN is good for general content but may stumble on specialized jargon without customization.

Is SYSTRAN Translate easy to set up for a non-technical person?

Yes, for basic use. You sign up, get an API key, and can start translating text or files through the web interface. The API integration is more complex, but the web tool is straightforward.

SYSTRAN Translate wins for simplicity and speed; ModernMT wins for adaptive learning and formatting – choose based on whether you need a quick fix or a long-term learning partner.

If you just need to translate a few documents or a website quickly without fuss, go with SYSTRAN Translate – it's simpler and faster to start. But if you're a business that translates the same kind of content over and over and want the tool to learn from your edits, ModernMT is worth the extra setup and cost.
