Show HN: PoLibre – FOSS .po editor for machine assisted translation

LibreTranslate released PoLibre, a free and open source .po editor for machine-assisted translation with built-in support for LibreTranslate and offline/online LLMs including Claude, Gemini, OpenAI, Ollama and OpenRouter. The single-binary desktop application also ships a command line for scripts and CI, with commands such as `polibre translate . -l it,de -p libretranslate -k KEY --dry-run`, GitHub Actions annotations and a JSON report, and it validates every translation for placeholders, HTML, URLs, plurals and length before writing it. Machine translation is optional, so PoLibre can be used as a standalone .po editor.
