Facts read from this source
-
Auto translation definition Report an error
“Auto-translation (AT) is a feature that allows you to translate your texts automatically using MT (machine translation) services, or AI models (LLMs).”
-
Auto translation providers Report an error
“OpenAI: AI-powered service that can translate texts with a very good quality and understanding of context and variables. Google Translate: One of the most popular translation services. Decent quality translations and fast processing times. DeepL: Machine translation service with AI features. Known for its high-quality translations, especially for European languages. Anthropic: Claude models by Anthropic, used with your own Anthropic API key. Gemini: Google Gemini models, used with your own Google AI Studio API key. OpenRouter.ai: Service that allows you to connect more AI providers and models for auto-translation, including OpenAI, Anthropic, Mistral, Gemini, LLaMA and others. Custom AI: You can also use your own AI model for auto-translation by providing a endpoint and API key in your project settings.”
-
Auto translation availability Report an error
“Auto-translation is available for all plans, but the number of characters you can translate depends on your plan.”
-
Auto translation scope Report an error
“With the auto-translation feature, you can translate automatically a single translation, an entire language or all languages at once.”
-
Auto translation default behavior Report an error
“By default, all auto-translation requests update only untranslated texts in your project. You can change this behavior in the additional options section to force translate all texts.”
-
Auto translation quick option Report an error
“Quick Auto-translate option uses the translation provider configured in the language settings.”
-
Auto translation options Report an error
“Override existing translations (to re-translate all texts, even those that already have a translation) Allow using keys as source text (for keys without source text).”
-
Auto translation background Report an error
“The auto-translation process runs in the background, so you can continue working on your project while the translations are being processed.”
-
Auto translation automation triggers Report an error
“With auto-translation automation, you can run auto-translation automatically when: new texts are added to your project source texts are updated”
-
AI context Report an error
“You can fine-tune the auto-translation process by providing additional context to translation services that use AI like OpenAI, Anthropic, Gemini, OpenRouter.ai and DeepL. For example, you can specify the tone of voice, style, or any other specific instructions for the translation, or just give more background information about your project.”
-
AI per language context Report an error
“For AI models, you can also set the context for specific languages in the Languages tab. Click on the language options (three dots), open Settings, and enter your custom prompt in the Additional context for AI field.”
-
AI key context Report an error
“SimpleLocalize additionally provides the AI provider with context from translation keys and translation data (e.g. key description, key settings), which helps improve translation quality.”
-
Glossary Report an error
“Glossary helps keep translations consistent when using auto-translation. They allow you to give AI provider or DeepL hints on how to translate specific words or phrases.”
-
Deepl own key glossary sync Report an error
“When using your own DeepL API key, SimpleLocalize automatically fetches glossaries from your DeepL account and uses them during auto-translation.”
-
Deepl builtin glossary plan Report an error
“When using SimpleLocalize built-in DeepL, you can create and manage glossaries directly in SimpleLocalize project settings (available from Team plan).”
-
Custom AI endpoints Report an error
“/v1/responses - newer endpoint, that supports more features (recommended) /v1/chat/completions - legacy but still widely supported”
-
Local AI models Report an error
“You can also run an AI model locally on your machine for auto-translation. To do this, set up a local server that exposes one of the supported endpoints mentioned above. Use LM Studio to run your local models and expose the API endpoint to SimpleLocalize via ngrok.”
-
Translation memory perfect matches Report an error
“Apply perfect matches: When enabled, SimpleLocalize will automatically apply translations that are an exact match in the Translation Memory, before running auto-translation. This can save you time and reduce costs if you have many repeated texts in your project.”
-
Large texts limit Report an error
“Allow to auto-translate large texts (over 25,000 characters)”
-
Custom API key quota Report an error
“Using your own API key for auto-translation doesn't affect the auto-translation quota, so you can translate as many characters as you want.”
-
Variable exclusion Report an error
“Exclusion variables help auto-translation providers to better understand which words or phrases should NOT be translated during the auto-translation process.”
-
Exclude words phrases Report an error
“You can add a list of words or phrases which will be automatically excluded on every auto-translation. This option is always enabled.”
-
Icu message exclusion Report an error
“SimpleLocalize automatically detects ICU messages and excludes variables used in those messages.”
