Request a tool
If you searched for a calculator and came up empty, that gap is exactly what we build. Tell us what you were trying to work out.
What happens to your request
- A person reads it. Every request lands in the same list we choose each week's build from.
- We check whether a good tool already exists. If one does, we'll point you to it rather than build a worse copy.
- If we build it, it ships to the same standard as everything else here: a cited formula, published test cases, and a dated source — how we verify.
We can't build everything, and we won't promise dates. But the requests that name a real situation — not just a formula — are the ones that usually become tools.
