What is Tolgee AI Translator?

Tolgee is an open source localization platform built for developers and translators who need to manage app translations efficiently. The platform's core philosophy is making translation management accessible within the development workflow rather than requiring a separate localization workflow disconnected from coding.

Tolgee integrates with web frameworks through its JavaScript SDK and with native mobile apps through iOS and Android SDKs, connecting the localization management layer directly to the application codebase.

In-context editing is Tolgee's most distinctive feature, allowing translators and developers to edit string translations directly within the running application rather than in a separate translation management interface.

By holding the ALT or Option key and clicking on any text element in the application, the user opens an editor for that specific translation string in its actual visual context.

This context-aware editing reduces translation errors caused by strings being too short, too long, or tonally wrong for the actual UI position where they appear.

Machine translation integration connects Tolgee to DeepL, Google Translate, AWS Translate, Azure, and Tolgee's own AI Translator in a unified interface.

Translators can get suggestions from all connected providers simultaneously and configure which provider to use per language, allowing optimization for translation quality in specific language pairs where one provider outperforms others.

Translation memory automatically suggests translations based on previously approved translations within the project, including a similarity percentage and the original text context, accelerating work on new strings that are similar to previously translated content.

Frequently Asked Questions

How does Tolgee in-context editing work?
Tolgee in-context editing allows translators and developers to click directly on text within the running application to open a translation editor for that specific string. Holding the ALT or Option key and clicking on any translated text element opens an inline editor showing the string in its actual visual context within the application. This allows translators to see exactly how a translation fits in the UI and correct issues with length, tone, or clarity that would not be visible in a standalone translation management interface.
Which machine translation providers does Tolgee support?
Tolgee supports DeepL, Google Translate, AWS Translate, Azure Cognitive Services, and Tolgee's own AI Translator. Suggestions from all connected providers are displayed simultaneously in the translation interface, and providers can be configured per language to use the best-performing option for specific language pairs. Translation AI usage is priced at 0.08 MT credits per input token and 0.3 MT credits per output token for the Tolgee AI Translator and AI Playground features.
Is Tolgee free to use?
Yes. Tolgee is open source and free in several ways. Open source projects can use the cloud version at no cost. Commercial projects can use the cloud version free up to 500 translation keys. Self-hosting on own infrastructure is free with unlimited translation keys and up to 10 seats on the community version. A licensed plan is required for self-hosted deployments with more than 10 seats or for advanced features and support beyond the community version.
What is the Tolgee MCP server?
Tolgee exposes an MCP (Model Context Protocol) server that allows AI coding assistants to interact with the translation management platform directly. Through the MCP integration, AI tools can search translation keys, create and update translations, manage languages, and trigger machine translation without requiring a human to navigate the Tolgee interface. This integration connects AI-assisted development workflows to the localization management layer for teams using AI coding tools like Claude, Cursor, or other MCP-compatible development assistants.
Can Tolgee be self-hosted?
Yes. Tolgee is open source and can be self-hosted on any infrastructure. The self-hosted community version is free with unlimited translation keys and up to 10 seats, providing core localization features and machine translation using the organization's own API keys for DeepL, Google Translate, and AWS Translate. A licensed plan is available for organizations that need more than 10 seats or advanced features and support on their self-hosted deployment. Self-hosting gives organizations full control over their translation data.
