Add tasks, or import a plan you exported earlier.
Work Plan Builder
List tasks with durations and finish-to-start dependencies, and get dates computed over working days, skipping weekends and the holidays you enter. See a Gantt chart, and export XLSX, PDF or JSON.

Good to know
- Dependency loops, and manual dates that end before they start, are flagged rather than scheduled.
- Holidays are only the ones you enter. None are assumed.
- Nothing is saved in the browser. Export JSON and import it to carry on.
Your files stay on your machine
This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.
These are the free ones — see the full suiteHow big a file can it take?
There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.
- Dates recompute as you type, which stays quick to around 500 tasks.
- A long plan on a wide date range makes a large chart, so the PDF continues across pages.
Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
