Free tools that finish the job

Calculators and planners that give you a finished answer — a materials list, a printable plan, a number you can act on. Everything runs in your browser: nothing is uploaded, nothing is stored, no account needed.

Tools

The first tools are being built. Each one ships only when it does something useful end to end — not a placeholder.

Why these tools are different

• They finish the job. Most calculators hand you a number and stop. These produce the thing you actually needed: a shopping list, a cut plan, a printable sheet.
• Your data never leaves your device. The maths runs in your browser. There is no server to send it to.
• No sign-up wall. No email, no account, no trial.
• They remember your inputs. Come back tomorrow and your numbers are still there.
