Toolsnug is a quiet collection of small, useful tools — calculators, converters, generators, and a handful of everyday utilities — built for people who want a straight answer without the friction.
Most online tools have drifted in a direction that is hostile to the people using them. Pages take eight seconds to load behind ad carousels, paywalls appear after the first calculation, popups want an email address before showing the result, and the actual answer is buried under five paragraphs of low-effort SEO filler. Toolsnug is built against that pattern.
Every tool here loads in well under a second, runs entirely in your browser, and gives you the answer immediately. Numbers you enter into a calculator stay on your device — they are never transmitted to any server. There are no accounts, no signups, no email-gated downloads, no third-party tracking pixels, no autoplay video. The explainer prose under each tool is written by a human and exists to actually explain the formula and the inputs, not to pad the page for search rankings.
The site is built as static HTML with a small amount of client-side JavaScript. It works offline once the page has loaded. It is accessible by default — every tool is keyboard-navigable, screen- reader-tested, and respects your operating system's reduced-motion and dark-mode preferences. None of these are features in any marketing sense; they are the floor of what a tools site should do.
How is this funded?
The long-term plan is to fund Toolsnug through display ads — they are not running yet. When they are, the network will be one that does not use behavioural tracking, third-party cookies, or cross-site profiling. A single contextual ad slot, served based on the page itself rather than on who you are. No popups, no autoplay video, no interstitials, no email-gated paywalls. Free always means free; the ads exist so the site can sustain itself without subscriptions.
Who is behind it?
I'm Jan Jetze Beitler, an independent developer in the Netherlands. More of my work lives at janjetze.nl. Another small project I run is steekem.com — a way to share short private notes through one-time, self-destructing links.
I've been building with AI agents for a while now. With Toolsnug I wanted to try that on something real — small, useful tools that load fast and don't waste your time, and that I'd want to use myself.
How the work splits: AI does most of the writing and most of the coding. I decide what gets built, what stays, what gets cut, and I'm accountable for what is here. I don't read every line — but if something on the site is wrong, that is on me, not on the model that drafted it.
