XER Compare
Drop two updates of the same P6 schedule and read what changed between them: the finish shift, which milestones moved, what joined or left the critical path, where float was eaten, and the logic and scope edits. The update review, without opening Primavera.

The update brief what a reviewer would write, generated from the two files
How it works. Both files are parsed and compared in your browser with no server, so confidential schedules stay on your machine. Activities are matched by their activity code (the identifier that survives between updates), so a renumbered internal id does not read as a change. Dates follow the same reading protocol as XER Health: actual dates before stale forecasts. Float is read from P6's own values. This is the update companion to XER Gantt and XER Health.
