Direct answer
What is Crowdin?
Crowdin is a cloud-based localization platform that synchronizes continuous translation across code repositories, design tools, and CMS platforms using AI models, translation memory, and human review.
Crowdin is an AI-powered localization and translation management platform designed to automate multilingual content workflows for software, mobile applications, websites, games, marketing assets, and technical documentation. It connects directly to version control systems like GitHub, GitLab, and Bitbucket, pulling source text automatically when code is pushed and opening pull requests once translations are completed. Beyond traditional translation memories and glossaries, Crowdin integrates AI pre-translation using multiple LLM providers such as OpenAI, Google Gemini, Anthropic, DeepSeek, Mistral, and Azure AI. Its context tools—including Context Harvester CLI, screenshot visual detection, and website context extractors—provide visual and technical UI cues to AI engines and human translators to reduce ambiguity. Crowdin also includes an in-context translation editor, over-the-air (OTA) content delivery for mobile applications, AI QA validation, and an AI Dubbing Studio for localized voiceovers across more than 100 languages.
Crowdin combines direct two-way Git synchronization with deep context harvesting (CLI, live web extractors, and UI screenshot analysis) and multi-LLM orchestration, allowing AI engines and translators to receive exact code and visual context before generating translations.
