Show HN: Co-Op Translator – Automate Docs and Image Localization (opens in new tab)

We created Co-op Translator to solve a real problem: scaling documentation localization across multiple languages in a CLI or CI/CD-friendly way.

While contributing to Microsoft's open-source education repos (like ML-for-Beginners), we hit a bottleneck:

Every small update in Markdown or diagrams had to be manually reflected across 10+ translated folders. It wasn't sustainable.

So we built Co-op Translator — a CLI and GitHub Actions toolkit that automates both text and image translation using Azure AI or OpenAI APIs.

It's designed for maintainers, educators, and developer teams who want to localize documentation without the manual grind.

It supports both public and organization-level GitHub Actions setup, and works with either Azure OpenAI or OpenAI directly. No vendor lock-in.

Note: I'm not a Microsoft employee. I maintain Co-op Translator as a community contributor within Microsoft's Azure OSS ecosystem.
