How it works

Open the tool and enter your inputs.
Copy or share the result (share link encodes state in the URL).
Adjust until everyone agrees on the rule.

Why this exists

MDN: Set (unique values)
Grammarly: Avoid overused language (repeated words)

Links show the real-world friction. The tool itself does not upload your data.

FAQ

Does this tool upload my data?

No by default. Most tools run locally in your browser. See the Privacy page for details.

What does “Share link” do?

It encodes your inputs into the URL hash so you can share without a server.

Is the result “official” or legally/financially accurate?

It’s a calculator, not advice. For critical cases, verify with official sources.
