What are localization quality checks?

Quality checks are automated rules that compare source and target content to identify issues before localized files are released. They can flag missing placeholders, changed markup, incorrect spacing, length discrepancies, empty targets, duplicates, and terminology issues.

In LingoHub, these checks are part of the localization workflow, giving translators and reviewers a clear view of issues that need attention before content moves forward.

How does LingoHub use AI to check translation quality?

LINA, the AI inside LingoHub, checks each translation it writes against the QA rules you set: placeholders, HTML tags, length limits, glossary terms, locale formats and more. As a Translator, LINA translates and pre-checks, and your team approves. As an Agent, LINA approves segments that pass, retranslates a failed one up to 3 times, and marks it Blocked if it still fails.

Localization context in LingoHub combining glossary, style guide, translation memory, labels, and additional project information to guide consistent translations.

Draft with your project context

LINA translates eligible content using your glossary, translation memory, style guide, and available context.

Check against your QA rules

Run checks for placeholders, ICU, tags, length, empty targets, glossary misses, and more as content moves through the workflow.

Retry, then hand off

When a segment fails a check, LINA as an Agent translates it again, up to 3 times, using feedback from earlier attempts. If it still fails, LINA marks it Blocked so a team member can step in.

Everything you need to know about quality checks in LingoHub

Got questions? We have the answers.

How do LingoHub quality checks help prevent technical bugs in my application?

Expand FAQ-entry Icon

Quality checks identify invalid placeholders and mismatched HTML markup before deployment, reducing software bugs caused by missing or extra variables. This ensures your translations are release-ready and do not break your software’s functional code.

Can LingoHub automatically fix common formatting mistakes?

Expand FAQ-entry Icon

Yes, the “Auto-correct” feature instantly detects and resolves inconsistencies such as punctuation errors or extra spaces. This reduces the manual review workload for managers and speeds up the entire approval cycle.

How do I ensure translated text fits within my UI elements?

Expand FAQ-entry Icon

You can customize length quality checks by setting character limits for specific components, such as buttons, headers, or pop-ups. The system provides immediate warnings if a translation exceeds these limits, preventing layout issues in your production environment.

Which quality checks can LINA run automatically?

Expand FAQ-entry Icon

You pick them per LINA in its QA settings. They cover minimum and maximum length, extra spaces and line breaks, missing or extra placeholders and HTML tags, required and not-recommended glossary terms, text left untranslated, quotation marks, date, time and number formats for the target locale, punctuation, end characters and duplicate words.

Does a person still approve translations LINA checks?

Expand FAQ-entry Icon

You decide per target language. With LINA as Translator, it translates and pre-checks segments, and a team member approves them. With LINA as Agent, segments that pass your checks are approved automatically, and your team only steps in on the ones LINA marks Blocked.
