Quick start

1 · Install

npm i -g i18n-ai-translate    # or yarn add i18n-ai-translate --dev
export OPENAI_API_KEY=•••     # or GEMINI_API_KEY / ANTHROPIC_API_KEY

2 · Translate a file

i18n-ai-translate translate -i i18n/en.json -o fr \
  -e chatgpt -m gpt-4o

Need more languages? Pass multiple codes (`-o fr es de`) or `-A` for **all** 180+.

3 · Translate a folder

i18n-ai-translate translate -i i18n/en -o fr es de \
  -e chatgpt -m gpt-4o

This recursively translates all `*.json` files in `en` and writes to `i18n/fr`, `i18n/es`, and `i18n/de`.

4 · Keep PRs up‑to‑date

Add a one‑liner GitHub Action to auto‑translate whenever `en.json` changes:

- uses: taahamahdi/i18n-ai-translate@master
  with:
    json-file-path: i18n/en.json
    api-key: ${{ secrets.OPENAI_API_KEY }}
