Tools that run in
your browser, not ours

Yes, every one of them. There is no paid tier, no trial, no credit limit and no feature held back behind a sign-up. The site is funded by advertising, which is why you will see ad slots on the pages, and that is the whole business model.

No. There is no login, no email capture and no account system on this site at all. Open a tool, use it, close the tab. Nothing is remembered about you between visits except settings a tool deliberately saves in your own browser, such as a japa count.

Nowhere. Every calculator, converter, counter and generator runs entirely in your browser using JavaScript. The numbers you type, the files you convert and the text you format are processed on your own device and never sent to a server. That is also why the tools work instantly and keep working on a weak connection.

The maths is exact - formulas are documented on each tool page so you can check the working yourself. Where a tool estimates rather than calculates, such as food calorie counters, the page says so plainly and explains how much room to leave around the figure. We would rather tell you the error bar than pretend there is not one.

Yes. Every tool is built mobile-first and tested at phone width, with touch-sized controls and result cards that stack into a single readable column rather than shrinking a desktop table. There is no app to install and nothing to update.

Please do. Most of what is on the site started as somebody asking for something specific that existing tools did badly. Email the address on the contact page with what you need and what the current options get wrong, and it goes on the list.
