React 19, TypeScript, Vite, Tailwind CSS 4, jspdf.

Install and customise

The How to install and How to use tabs list the steps. In short: unzip, npm ci, npm run dev, then copy the tool folder into your own app if you want to embed it.

Good to know

• A browser-only tool: there is no backend or database in the code.
• Planning estimate only; calibrate the weights to your own projects.
