I’ve been building a CLI tool to automate i18n string translation based on JSON files (like used in i18n frameworks).

It currently implements Google Gemini or Ollama support with flexible model choices. Also deduplicates across files and caches results to avoid repeats and reduce API usage, plus it uses dynamic batch sizing. Additionally, it implements also a MCP server, supports batch processing, doing translations to multiple languages at once with filename templating etc.

Would love feedback or ideas from others working on similar things.
