Questions about Crowdin
- Which AI model does Crowdin use?
- ChatGPT runs (partly) on Crowdin, Gemini, Claude. You connect an AI provider yourself (including OpenAI, Anthropic or Google) with your own key, in which case that provider's terms apply to your text (according to the provider); EU (Estonian) company; data is stored by default in the AWS data centre in the US (us-east-1), an EU data centre (AWS Ireland) can only be chosen with ChatGPT Enterprise (according to the provider); ISO/IEC 27001 certified and GDPR compliant (according to the provider); data processing agreement (DPA) with ChatGPT as processor (according to the provider); if you translate personal data, choose ChatGPT Enterprise with the EU data centre.
- What does Crowdin cost?
- free plan; Pro $ 50 per user/month, Team $ 150 per user/month, Team+ $ 450 per user/month; 14-day trial on the Team plan (Enterprise 30 days). Check the current price on the provider's website; rates change often.
- Who is Crowdin for?
- Crowdin is aimed at translation & localisation, IT & software development and non-profit & fundraising. It fits work such as producing a first translation draft and machine pre-translation (post-editing), keeping terminology and house style consistent with term bases and translation memory, and rolling out and maintaining websites, apps and software in multiple languages.
- What should I watch out for with AI in translation & localisation?
- Client source documents often contain personal data or trade secrets: never use the free consumer version of a translation tool for client material. Require a data processing agreement, check that your texts are deleted after translation and not used for training, and choose EU hosting where possible. Many translation contracts and NDAs with end clients prohibit passing texts to third parties without consent, so document which MT engine you use. And stay responsible for the content: AI translations read fluently but can reverse figures, negations and legal nuances.
