What is Tolgee AI Translator?
Tolgee AI Translator is an AI-powered localization tool for translating app text with context. It uses Tolgee’s contextual data, including key relationships, screenshots, key descriptions, project descriptions, language notes, and translation memory, to produce translations that are more accurate and natural than generic machine translation. It is designed to reduce the time and cost of localization while still allowing humans to review and refine the output.
The tool is built around autonomous or semi-autonomous translation workflows. You can add strings to Tolgee, let the AI generate translations, and then review them in the platform. Tolgee’s contextual technology automatically extracts context from your app, so translators do not need to constantly ask developers or designers for extra explanation.
Tolgee also includes customization features for improving AI output. You can tailor prompts, compare different LLM models, test prompt variations in the AI Playground, and use project descriptions, language-specific notes, and key descriptions to shape tone and terminology. It can connect to providers like OpenAI, Anthropic, and Google Gemini, including self-hosted options.
It is aimed at developers, localization teams, product teams, and translators who want faster app translation without losing consistency or context. It is especially useful for teams that need scalable localization workflows and want to combine AI automation with human review.

Frequently asked questions about Tolgee AI Translator
What does Tolgee AI Translator do?
It translates app strings using Tolgee’s contextual data so translations are informed by the key name, surrounding relationships, screenshots, descriptions, language notes, and translation memory. The goal is to make localization faster while keeping translations consistent and contextually accurate.
How is Tolgee AI Translator different from generic machine translation?
Tolgee uses application-specific context rather than translating strings in isolation. It can see how keys relate to each other, access screenshots or Tolgee Context, and use extra project information, which helps it handle ambiguous text and preserve meaning better than a generic translator.
What context can Tolgee use for translations?
Tolgee can use Tolgee Context, key descriptions, project descriptions, language notes, screenshots, and translation memory. It also uses related-key context gathered from the app through the SDK to improve accuracy.
Can I customize Tolgee AI Translator?
Yes. You can customize prompts in the AI Playground, edit default prompt fragments, use variables for key data and screenshots, and add project descriptions or language-specific notes. Tolgee also supports AI Translation Customization for tuning tone, terminology, and cultural sensitivity.
Which AI providers does Tolgee support?
Tolgee can connect to providers such as OpenAI, Anthropic, and Google Gemini, including self-hosted solutions. It also supports multiple providers with smart load balancing to help avoid rate limits.
Does Tolgee support human review after AI translation?
Yes. The website explicitly promotes a workflow where AI generates translations first and humans then review and refine the texts. This is positioned as the best way to balance speed with quality.
Is Tolgee AI Translator available for self-hosted installations?
Yes, but some features are plan-dependent. The site says AI Translation Customization is available in the cloud Business subscription or higher and in subscribed self-hosted instances using the Tolgee AI translator.
Do I need Tolgee Context for good results?
No, Tolgee says the translator can still improve translation quality without Tolgee Context because it knows the key name and can use descriptions, project descriptions, language notes, and translation memory. However, Tolgee says context can improve ambiguous translations radically.
What is included in the free plan?
The Free cloud plan includes 500 keys, 3 seats, and 10,000 MT credits. Tolgee also describes it as a free plan with localization essentials such as in-context translating, translation memory, machine translations, auto translation, activity log, one-click screenshots, single content delivery, and the Figma plugin.
How much does AI translation cost?
Tolgee charges MT credits for AI Translator and AI Playground based on LLM tokens. The pricing page says one input token equals 0.08 MT credit and one output token equals 0.3 MT credit, and gives an example that a typical prompt without screenshots can be about 450 tokens and 42 MT credits.
