ToolBox (mhouse.top) brings together 260+ free online tools across development, encoding, AI workbench, media processing, documents, charts, and daily utilities — plus a web directory, AI News Radar, and Jing-Jin-Ji local-law lookup. Open a tab and get work done — no friction.
Great tools should be fast, free, and private — not locked behind paywalls, sign-up walls, or data-hungry cloud services. We believe you should finish work in the browser without sending files to unnecessary servers.
Most tools process data on-device with WebAssembly and local JavaScript. Files, text, and media typically never leave your browser. Site-wide Google Analytics / Microsoft Clarity measure traffic — see the Privacy Policy.
