Your Online Helper is exactly what the name suggests: a lightweight set of everyday tools, all running in your browser, none of them asking for an account or sending your data anywhere.

What you'll find here

• SitePulse — check whether any website is up or down in real time.
• Mortgage Calculator — estimate monthly payments, interest, and amortization.
• Conversion — convert units across length, weight, temperature, volume, area, speed, time, and data.
• Color Picker — grab colors, copy HEX / RGB / HSL, and explore harmonies.
• Lottery Picker — random numbers for popular lotteries (for entertainment only).
• Password Generator — strong random passwords using your device's crypto source.
• QR Code Generator — turn text or URLs into downloadable QR codes.
• Word & Character Counter — live counts as you type.
• Encoder & Decoder — Base64 and URL encoding/decoding.

How it's built

Everything is plain HTML, CSS, and JavaScript — no frameworks, no tracking scripts, no third-party analytics. Each tool is self-contained. If you're curious about how something works, you can open the page's source and read it end to end.

Privacy

Tools save their state in your browser's local storage, where it stays. Nothing is uploaded to a server unless a specific tool says so (SitePulse uses public proxies when a direct check is blocked). See the Privacy at a glance page for the short version, or the Legal page for the full details.

Installing as an app

Your Online Helper can be installed on your phone or desktop like a native app. Look for "Add to Home Screen" or "Install" in your browser's menu. Once installed, it opens in its own window and works offline.
