Do I need to upload my PDFs?
Core PDF editing and measurements run on your device. The account service does not need your drawings. Read about data handling.
Can I export quantities to a spreadsheet?
Yes. Export measurements as CSV or copy a takeoff legend as a table. Values and units use separate columns so you can use the numbers in formulas.
Can others open my marked-up PDFs?
PlanDiFy saves standard PDF annotation appearances. Advanced measurement data and custom tool behavior may differ between PDF applications.
When can I download PlanDiFy?
Public downloads and account registration are being prepared. Availability will be listed on the Downloads page. Introductory access dates and pricing have not been announced.
