About suggesting tools

Universe Tools grows thanks to simple, practical ideas from real users. If you often think “I wish there was a quick tool to do this,” this page is the fastest way to share it. A good suggestion is usually very short but specific: explain the goal of the tool, list the inputs a user would type (numbers, dates, units, options), and describe the output they expect (a result value, a table, a conversion, a formatted text, a downloadable file, etc.). If you can, add one concrete example: “If I input X and Y, I should get Z.”

Why this helps: most tools are easy to build when the use case is clear. For example, a converter needs the units and formulas; a calculator needs the required fields and the exact rules; a generator needs the format and constraints. With a clear description, we can implement your idea faster and ensure the tool matches your real-world need.

Privacy stays the same as on the rest of the site: this page does not send anything to a server. It simply opens your email application with a prefilled draft using mailto. You remain in control: you can edit the message, change the recipient, or discard it before sending.

Tip: include the tool name you imagine (even a rough one). It helps us categorize it and create the page faster.

What is this page for?

This page lets you suggest a new calculator, converter, or generator for Universe Tools. You describe your idea in a few lines, then your email client opens with a ready-to-send draft. Nothing is stored on the website.

Who is this useful for?

It’s useful for anyone who frequently needs a quick tool and wants to request it: students, freelancers, business owners, people comparing prices, converting units, planning budgets, or automating small everyday calculations.

Concrete examples

  • “I want a tool that converts net salary ↔ gross salary with country presets.”
  • “A calculator for paint needed: room size + coats + coverage → liters.”
  • “A generator that outputs a clean invoice text from fields (client, items, VAT).”
  • “A converter for m³ ↔ liters ↔ gallons with quick presets.”

Common mistakes

  • Not specifying the exact inputs (units, ranges, options) and the exact output format expected.
  • Not giving a concrete example (X + Y should return Z), which makes the rules ambiguous.
  • Mixing multiple tool ideas in one message (harder to implement and categorize).

Alternatives and limitations

You can also suggest tools via social media or contact pages, but this page is designed to be fast and structured. It uses mailto, so it depends on your device having an email client configured. If no email app is configured, nothing will be sent.

Educational summary

A strong tool suggestion is short and specific: (1) goal, (2) inputs, (3) expected output, and (4) one example. This page helps you send that in seconds while keeping the same privacy principle as the rest of Universe Tools: local-only behavior and no server-side storage.
