Show HN: I created an NPM package to AI sync my translations in seconds (www.npmjs.com)

linguaisync is a new open‑source NPM tool that automates synchronization of missing translations by calling the OpenAI API. After installing (npm i linguaisync) and exporting your OPENAI_API_KEY, you point the tool at a locales directory and a base language via a JS/JSON config. Run npx linguaisync --all --dry-run to preview or npx linguaisync --all to sync; you can target specific languages, export missing keys, or integrate programmatically using createConfig, analyzeLanguages and syncLanguages. It preserves formatting, HTML and placeholders (e.g., {{var}}), supports multi-file projects, and offers dry‑run, verbose and output options for safe workflow integration. For the AI/ML community this is a practical example of applying LLMs to a common developer workflow: it reduces manual localization effort, speeds iteration, and standardizes quality checks. Technical knobs include batchSize for API efficiency, model and temperature settings (example: model: "gpt-4o-mini", temperature: 0.3), and smart batching to control cost and rate limits. It supports many languages out of the box, is MIT licensed, and can be wired into CI (npm scripts shown) to automate translation maintenance while keeping placeholders and structure intact — a useful pattern for teams wanting LLM-driven localization without sacrificing formatting or pipeline safety.
