Using AI in the Editor

After configuring a prompt with the AI in editor type, Crowdin AI can be used in the Editor as an AI Assistant for translators and proofreaders. This AI Assistant can be communicated with in a chat format, allowing you to send prompts and receive replies.

The AI Assistant is context-aware, meaning it knows the string the translator is working on, the related glossaries, TM matches, the maximum acceptable length of the translation, the related screenshots, etc. This contextual awareness enables the AI Assistant to provide more accurate and relevant assistance.

Here are some tasks the AI Assistant can help with:

• Correcting TM suggestions: If you get a 60% match, the AI Assistant can improve the remaining 40%, ensuring consistency with your terminology and previous translations.
• Serving as an advanced dictionary: The AI Assistant can provide term definitions, translation variants, synonyms, and more.
• Suggesting translations: Similar to other MT tools, the AI Assistant can suggest translations which you can further refine based on your specific needs or save as is.

In addition, the AI Assistant can help in translating knowledge base articles by providing short summaries, helping you grasp the content quickly before translating.

When working in the Editor, you can start using the AI Assistant by clicking the AI Assistant tab in the right sidebar.

For faster and more efficient interaction with the AI Assistant, you can use prompt shortcuts. By default, there are three prompt shortcuts available:

• Rephrase
• Shorten
• Translate all

To add your own prompt shortcuts, follow these steps:

1. Click in the upper-right corner to open the AI settings.
2. Click Add shortcut.
3. Specify a shortcut name and a prompt it will be using.
4. Click Save.

Additionally, in the Editor Settings > AI tab, you can create a custom prompt to provide the AI Assistant with a specific set of instructions that are sent each time you make a request. Note that the custom prompt is project-specific.

When sending prompts to the AI Assistant, the instruction priorities are considered in the following order:

1. Instructions specified in the AI in editor prompt settings.
2. Instructions specified in the custom prompt settings.
3. Instructions specified in the prompt shortcut or manually entered in the AI Assistant chat.

AI QA Check

AI QA Check uses AI to automatically evaluate translations against defined quality standards. It helps translators quickly identify and resolve issues, ensuring accuracy, consistency, and compliance with project-specific requirements. AI QA Check complements and extends default QA Checks by providing comprehensive flexibility, reducing manual review efforts, and enhancing overall translation quality.

How AI QA Check Works

When enabled, AI QA Check evaluates each submitted translation against a set of customizable evaluation criteria (Evaluation steps) defined in the configured QA Check prompt. Issues detected by the AI appear directly within the Editor as warnings, along with concise suggestions for corrections.

Evaluation steps may include:

• Accuracy – Ensuring no content is omitted, added, or incorrectly translated.
• Fluency – Checking grammar, spelling, punctuation, and readability.
• Terminology – Confirming consistent and correct use of project-specific terms.
• Style – Verifying translations align with defined stylistic guidelines.
• Design – Ensuring translations fit design constraints, including length and markup.
• Locale Convention – Adapting formats for dates, currencies, addresses, and more.
• Cultural Adaptation (Verity) – Localizing culture-specific references appropriately.
• General Issues – Identifying other miscellaneous quality issues.

For example, if a translation deviates from established glossary terms or fails to meet local formatting standards, the AI will highlight this and offer recommendations, guiding translators to achieve compliance and consistency.

Setting Up AI QA Check

To use AI QA Check, create and configure a QA Check prompt. Each QA Check prompt contains clearly defined evaluation steps the AI follows to detect translation issues. Unlike other AI prompts, the QA Check prompt includes a dedicated Evaluation steps section, allowing you to customize, edit, or expand upon predefined checks.

You can also enhance the accuracy of the AI’s analysis by including various types of additional context relevant to your project’s content.

After configuration, you can assign a QA Check prompt as the default for either your entire organization or individual projects.

Applying AI QA Check in Projects

To enable AI QA Check in your projects, follow these steps:

1. Create and enable a QA Check prompt.
2. Set it as the default QA prompt in the project’s Settings > AI > Settings.
3. Enable the AI-powered check in the project’s Settings > QA Checks.

Once set, the AI continuously checks submitted translations, ensuring consistent compliance with your project’s quality guidelines.
