Hey Product Hunt! 👋 I built ToolsHub because I was tired of hunting for a reliable free PDF merger, then a QR generator, then a tax calculator — all on different sites covered in ads and paywalls. ToolsHub now puts 35+ tools in one place, across 8 categories — Documents, Codes, Business, Finance, Utility, Images, Converters, and Text. None of them upload your data anywhere. Everything runs in your browser. A few recent additions I'm proud of: the salary tax calculator now shows a full bracket-by-bracket breakdown for 10 countries, and the currency converter now supports 50+ world currencies (including PKR, INR, AED, and NGN) instead of just the major ones. The thing I'm most excited about: every calculation tool (BMI, loan EMI, salary tax, currency converter, etc.) is accessible as an MCP server, which means AI assistants like Claude can call them directly. Ask Claude "what's my BMI?" and it can call ToolsHub's API to answer. Happy to answer any questions — would love your feedback on which tools to add next!
