AI Translations is a new task type that enables you to quickly and accurately translate content in a fully automated way. It uses Lokalise AI assistant built on OpenAI's GPT API to automatically translate content taking into account context, such as your glossary terms, instructions you provide when creating a task, character limit for individual translations.



AI Translations is a new task type that is built on top of the Lokalise AI. AI Translations task provides the following capabilities:

  • Create a task to translate content in 30 languages and their variations (see full list below)

    • The task will be automatically assigned to Lokalise AI assistant

    • During the ongoing task, all translation keys will be automatically locked until Lokalise AI assistant finishes the job for the respective language

  • Provide additional instructions to Lokalise AI upon task creation, such as specifics about target audience, tone of voice or formality level to be used

  • Receive notifications upon language translation completion

  • Leverage existing terminology to ensure that all translations respect your glossary terms

On average, AI Translations takes just a few minutes to complete but this heavily depends on the amount of content and number of languages that you decide to perform it on. You would be able to see estimated time of completion once you selected languages and scope.

Supported languages

AI Translations currently supports 30 languages and their variations for different locales: English, Russian, Chinese Traditional, Chinese Simplified, Japanese, Spanish, German, French, Portuguese, Arabic, Korean, Italian, Dutch, Turkish, Polish, Swedish, Indonesian, Czech, Hebrew, Danish, Finnish, Romanian, Hungarian, Vietnamese, Hindi, Lithuanian, Latvian, Slovak, Estonian, Ukrainian.

This is not an exhaustive list. It will be updated based on the quality level and our confidence in quality for the respective language. In case you want us to support other languages and are happy to help with translation quality evaluation, let us know.

Using AI Translations

Creating a new AI Translations task

To get started with AI Translations, open any project in Lokalise and create a new task. There are two ways to create a task.

First, you can select multiple keys in the editor by ticking checkboxes next to their names and then choosing Create task... from the bulk actions menu. This will open the task creation page with a predefined task scope, limited to the keys you have just selected.

Alternatively, open your project and proceed to the Tasks page:

Click Create a task to open the task creation wizard.

In the task creation wizard you will see a new task type called Automatic translation (Lokalise AI). Choose this type:

Provide the task name and fill in instructions for Lokalise AI. These instructions will be used to translate content more accurately.

Some examples of what you can include as instructions:

  • Translate idioms into equivalents appropriate for the target audience.

  • Maintain a conversational tone.

  • Use simple language.

  • Do not translate idiomatic expressions word-for-word.

  • Avoid unnecessary abbreviations.

Instructions field has a 2000 character limit. Once you have completed instructions, proceed to the next step.

You can also attach a style guide to the task. Please refer to the corresponding article to learn more.

Adjusting task options

Advanced task options will be limited to the following:

  • Save translations performed by AI to Translation memory — you can choose whether you want translations performed by Lokalise AI to be saved into your Translation memory or not.

  • Tag keys after the task is closed — tag translation keys added to the current task once it's completed. This way you'll be able to easily identify these keys afterwards.

  • Save as task template — this task can be used as a base when creating other tasks (scope and languages will be pre-selected).

Adjusting task scope

Select the scope and languages:

  • Task scope — adjust the filter to choose the keys that should be added to the task.

  • Source language — choose the language that should be used as a reference for performing quality evaluation.

  • Target languages — choose one or more languages that should be evaluated by Lokalise AI assistant.

  • Task assignees — you won't be able to modify assignees as all languages will be assigned to Lokalise AI assistant for automatic translation.

Task summary

To the right, you'll see the task summary and your Lokalise AI words balance:

In this summary you can see the AI words quota for your team and the number of AI words to be consumed in this exact task. Please refer to the Team quotas article to learn about the words quota.

You will also see the estimated delivery time for this task. Please note this is an approximate number and it can fluctuate depending on the load on our system.
