Free i18n tools
Small, sharp tools for everyday translation work. No signup, nothing stored.
Untranslated Key Detector
Scan any website for leaked i18n keys: dot-notation identifiers, missing-translation markers and unrendered placeholders your users can see.
Blade Hardcoded String Scanner
Paste a Blade template and find text that should be behind __() — with suggested keys and a generated lang file.
Pluralization Tester
Pick a language, type a number, see which CLDR plural category applies — live, via your browser's Intl.PluralRules.
AI Translation Cost Calculator
Keys × languages = quota units. Estimate the initial run and the monthly churn for your project.
Lang file converters
Convert between Laravel PHP arrays, JSON, YAML and CSV — nesting, placeholders and plural pipes preserved.
