About Computezy
Free, browser-based tools for everyday tasks — no download, no sign-up, no nonsense.
What it is
Computezy is a growing collection of free, browser-based tools that work instantly without any installation or account. Each tool is purpose-built to be fast, accurate, and genuinely useful — the kind of utility you'd normally need to download an app or find a cluttered website for.
Everything runs in your browser. No data is sent to any server. Open a tool, use it, close the tab — there's nothing left behind.
Our tools
Four tools are live now, with more on the way. Each has its own dedicated page with full details, features, and a FAQ.
An accurate screen ruler that renders at true physical size using your display's pixel density. Supports cm, mm, inches, points, and pixels with three calibration methods.
A live word counter that tracks words, characters (with and without spaces), sentences, paragraphs, and reading time the moment you start typing — no button clicks needed.
Instantly converts text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case. Paste, pick a style, copy — done.
An animated spinning wheel for fair random selections. Add names, spin, remove winners after each draw, and save lists for reuse — perfect for giveaways, classrooms, and team decisions.
How we build
No barriers
No sign-up, no paywall, no mandatory download. Open the URL and start using it.
Privacy by default
Tools process your input locally in the browser. Nothing you type or measure is sent anywhere.
Built for accuracy
We take precision seriously. The ruler calibrates to your actual screen density; the counter matches the word-counting rules of major word processors.
Always free
No premium tier, no feature gates. Every tool is free in full, for personal and commercial use.
What's coming
The roadmap includes tools across categories — developer utilities (JSON formatter, JWT decoder), calculators (compound interest, age, quadratic solver), science tools (projectile motion, molar mass), and more. Each will follow the same standard: open and use, no friction.
