How it works

Continuous Localization Workflow

1. Upload source content – Developers push code to repositories; Crowdin detects changes and pulls new strings.
2. Add context – Automatic context harvesting with screenshots, style guides, glossaries, Translation Memory, and vector databases.
3. Pre-translate texts – Generate draft translations using TM, MT engines (e.g., DeepL, Google Translate), and AI providers.
4. Quality assurance – Translators and proofreaders review translations for accuracy and context; QA checks flag issues.
5. Deployment – Approved translations sync back via CI/CD; auto pull requests are created.
6. Continuous localization – The workflow runs 24/7, automatically triggering whenever new content is added.
