Crowdin AI

Crowdin integrates with top AI providers, including OpenAI, Google Gemini, Microsoft Azure OpenAI, and more, allowing you to leverage advanced AI-powered translations that consider additional context at different levels. These translations can be applied to your content with a few clicks using pre-translation via AI.

Additionally, you can expand your AI provider options by installing respective applications from the Crowdin Store.

Configuring AI

Crowdin AI integration provides powerful capabilities for enhancing localization workflows. Configuring AI involves setting up providers and creating prompts.

Configuring AI Prompts

Prompt engineering is crucial for guiding AI in understanding context and providing accurate translations. Customizing prompts within Crowdin ensures that AI algorithms comprehend the nuances of your project, resulting in improved translation quality.

  • Contextual Prompts – customize prompts to provide contextual information, such as project-specific terminology, style preferences, and target audience considerations. For example, include instructions on translating technical terms consistently or maintaining brand tone across languages.
  • Placeholder Utilization – incorporate placeholders to dynamically insert context-specific information into prompts, enabling AI to generate translations aligned with project requirements.
  • File-Level Context – use file-level context to provide instructions and contextual insights, enhancing AI’s understanding of content nuances. Include file descriptions, summaries, or references to glossaries and style guides.

To configure AI prompts, follow these steps:

  1. Open your profile and select AI on the left sidebar.
  2. In the Prompts tab, click on the needed prompt type (e.g., Pre-translate).
  3. Click Add prompt.
  4. In the appeared dialog, set the prompt parameters:
    • Select Enabled
    • Title
    • AI Provider
    • AI Model
    • Additional context (Basic mode) – specify which data will be included in the prompt using the following fields:
      • Company description
      • Project description
      • Audience description
      • String context
      • String identifier (key)
      • Translation max. length
      • Other languages translations – select specific language tranlations to be considered by AI as additional context or leave this field as is to use translations from all languages.
      • Glossary terms – allows AI to consider domain glossary terms.
      • TM suggestions – allows AI to consider TM suggestions.
      • File content – allows AI to consider a whole file as the context for translating a segment of strings, improving translation accuracy for text documents. Although, when using file content as an additional context it can lead to increased token usage, potentially resulting in additional costs.
      • File context – allows AI to consider a textual description of the file added in the file settings. Read more about File context.
      • Public project description – allows AI to consider public project description.
    • Advanced mode – click Advanced mode to compose your prompt in the most precise way. While composing your prompt in the Advanced mode, you can increase translation quality by leveraging context information in your prompts using the following placeholders:
      • %sourceLanguage% – The source language of a project.
      • %targetLanguage% – The target languages a project is translated into.
      • %json% – A collection of strings from the current segment, including the string identifier (key), context, text, maximum length, and translations to other languages (if the translations placeholder is specified).
      • %fileName% – The file name of the current segment.
      • %fileContext% – The file context of the current segment (can be provided via the file settings modal in the ‘Files’ tab).
      • %fileContent% – The source file content of the current segment.
      • %tm% – Translation Memory (TM) matches relevant to the current segment.
      • %terms% – All the glossary terms relevant to the current segment.
      • %fileTranslations% – Translations of the current segment into the specified language.
      • %projectName% – Crowdin project name.
      • %projectPublicDescription% – Project public description.
    • Project prompt availability – select specific projects where a prompt can be used or leave this field as is to allow a prompt usage across all projects.
  5. Click Create

Configuring AI Providers

Crowdin supports various AI providers, each offering unique models and features for translation tasks. By configuring providers, you can tailor AI functionality to suit your specific localization needs. Whether using managed by Crowdin services or integrating your own API keys, Crowdin enables seamless integration with AI services.
