Why these tools exist

Anyone who runs campaigns repeats the same small tasks every week: tagging links with UTM parameters, checking whether ad spend is paying off, working out cost per acquisition, and squeezing ad copy into character limits. Most tools for these jobs are buried behind sign-up forms, cluttered with pop-ups, or quietly send your data to a server.

Patawise Tools does each job well in a single page. Open a tool, enter your numbers, get the answer, and move on.

What makes them different

  • Private by design. Every calculation runs in your browser. The numbers, URLs and text you type are never sent to us.
  • Explained, not just calculated. Each tool shows the formula it uses, with worked examples, common mistakes and guidance on interpreting the result.
  • Fast on any device. Pages are lightweight, work on phones and desktops, and need no account.

How we check accuracy

Before a tool is published, its formulas are tested against hand-calculated examples, including edge cases like zero values and very large numbers. Pages that depend on platform rules, such as ad character limits, show when they were last verified, and we review them regularly.

Results are estimates for planning and analysis. They are not financial, legal or tax advice. If you spot an error, please tell us and we'll fix it quickly.

Who we are

Patawise Tools is built and maintained by Patawise, a software studio that designs and builds web platforms, mobile apps and AI-integrated products for clients around the world.

The tools are free to use. We keep them free by showing a limited number of clearly labeled ads, and ads never appear inside the tools themselves.
