What is i18nizer?
i18nizer is a CLI tool that automates the tedious process of internationalization in React and Next.js projects. It extracts hardcoded strings from your JSX/TSX files, generates AI-powered translations, and rewrites your components to use translation functions.
No runtime dependencies, no SaaS, no lock-in. Just a CLI that fits into your existing development workflow.
Key Features
AI-Powered Translations
Generate translations using OpenAI, Google Gemini, or Hugging Face at development time
Automatic Extraction
Extract translatable strings from JSX/TSX files with intelligent filtering
Component Rewriting
Automatically rewrite components to use t() translation functions
Smart Key Generation
AI-powered English camelCase keys for consistent, readable translation keys
Intelligent Caching
Cache translations and keys to avoid redundant AI requests and ensure consistency
Framework Integration
Built-in support for i18next, next-intl, and react-i18next
Why i18nizer?
Internationalization is essential but tedious. The manual process involves:
- Finding and extracting every hardcoded string
- Creating translation keys that are consistent and readable
- Manually translating content to multiple languages
- Rewriting components to use translation functions
- Maintaining JSON files across locales
i18nizer automates all of this, letting you focus on building features instead of managing i18n boilerplate. It works with your existing i18n setup—no runtime changes, no vendor lock-in.
