A collection of calculators powered by an AI translation system that automatically handles content localization, currency formatting, and number internationalization across all languages. No signup needed, no data collection - just fast, accessible tools for everyone.
Built on Next.js 15 and React 19 for lightning-fast performance. Strict TypeScript ensures reliability while Tailwind CSS delivers a responsive design. Supabase powers our database with rapid content delivery across all languages.
Good Tool is a side project by Trevor Loucks that started as an experiment in AI-powered translations. The system now handles localization for several other projects including Dynamoi and Hardly Creative.
