LogicReader

The logic behind every schedule, visible.

LogicReader is a schedule-intelligence platform for engineering and infrastructure projects. Compare revisions, build defensible logic, assess risk, summarise huge programmes, and audit every dependency — on top of the Primavera P6, MS Project, or Asta schedules you already produce.

Free, and free to keep using — open a schedule, read it, and work on it. We ask for your email so we can send you a confirmation link; nothing is shared. Paid plans, for building and exporting at scale, follow shortly — tell us what you need and we will shape them around it.
