As answered by people managing Diffee and Tools Kept Simple.
Tools Kept Simple's answer:
Every tool runs entirely in your browser, so nothing you type is ever sent to a server. There is no signup, no account and no paywall, and the tools keep working offline once visited. Each page does one job and keeps everything else out of the way: no pop-ups, no autoplay, no clutter.
Tools Kept Simple's answer:
Many free tool sites are slow, covered in ads or send your text to their servers. Tools Kept Simple is fast and calm, keeps your data on your device, and puts the answer first. Thoughtful extras come as standard: light and dark themes, keyboard shortcuts, shareable links, remembered settings and an installable app.
Tools Kept Simple's answer:
Anyone who needs a quick, private tool without signing up: office workers tidying lists and text, writers counting words, cooks converting oven temperatures and weights, students, and developers who want to encode, compare or check something fast.
Tools Kept Simple's answer:
It started from frustration with tool sites that bury a simple job under ads, sign-up prompts and tracking. The idea was the opposite: small tools that each do one job well, look calm, respect privacy and load instantly. New tools are added regularly, each built to the same standard.
Tools Kept Simple's answer:
Plain HTML, CSS and JavaScript with no framework, so pages load fast and run entirely in the browser. A service worker provides offline use and app install. It is hosted as a static site on Netlify.
