ToolkitBook
ToolkitBook is a free collection of browser-based utilities designed for immediate use. No accounts, no subscriptions, and no data uploads—just open a tool, get your work done, and move on.
I built this site to solve a recurring frustration. Whenever I needed a quick tool—to format JSON, generate a password, or convert units—I'd find myself searching the web, only to be met with intrusive pop-ups, cookie banners, and lackluster results. It was a constant drain on my time.
I eventually decided to build the utilities I was constantly looking for. One tool led to another, and ToolkitBook is the result: a single, distraction-free space for the tools I actually use, with all the unnecessary noise stripped away.
Everything on this site runs entirely within your browser. I use plain JavaScript and the occasional third-party library, but your data never reaches a server. Everything stays on your local machine. I don't treat that as a marketing feature; it is simply how these tools ought to work.
I add new tools whenever I notice a gap in my own routine or find a utility worth building. There is no formal roadmap or fixed schedule—just steady updates over time. If anything here saves you a few minutes, it has already served its purpose.
