P7 Free Scheduling

Open Pathizer P7

One .XER or .XML schedule file, or a USACE SDEF file

Takes
Your latest schedule update (.XER) and the one before it

The free tools show what’s in your schedule file. Reviewing all of your project’s updates, the Health Score and drafted narratives come with Enterprise. What Pathizer Enterprise adds.

Which tool to use

To build or edit a schedule, use P7 Free Scheduling. Set up projects, a WBS and activities, and link the activities. P7 works out the dates by critical path and draws a Gantt chart. It opens .XER and .XML schedule files, and exports .XER files.
To have your own AI help in P7, use Connect to AI. Your Claude or Codex can build and edit the open schedule. It works through a small program, called a connector, that runs on your computer.
To look at a schedule someone sent you, use the Schedule Viewer. It opens .XER and .XML files, Microsoft Project .xml files and USACE SDEF files. You can look, but not edit.
To check how well one schedule is built, use the Health Check. It runs the DCMA 14-point checks that one .XER file can answer. These are 14 standard checks schedulers use.
To see what changed between two updates, use Update Compare. It lists the activities and relationships that were added or deleted. It also shows changes to start, finish, duration and float.

What happens to your files

The Schedule Viewer, the Health Check and Update Compare open your file in this browser tab. Your file is never uploaded.
The Schedule Viewer sends Pathizer nothing about your file.
The Health Check and Update Compare send Pathizer a short note when the tool opens, when a file loads and when a result shows. The note says which tool and which step. It has nothing from your file.

What happens to your schedules in P7

Your schedules stay on your device. They are saved in this web browser.
In Chrome and Edge, you can also pick a folder on your computer. P7 saves your projects there as files.
If you have not picked a folder, P7 warns you after 5 minutes of editing. Until you pick a folder or download a copy, your work is only in this browser. If you clear your browser data, it is gone.
Connect to AI talks only to the connector on your own computer.
P7 sends Pathizer one short note a visit, and only if you allowed ad cookies and accepted the P7 privacy notice that describes it. It is sent the first time you export a .XER, create a project, schedule a project or connect your AI.
That note says which of those you did, the ad link you clicked to get here, and when. It has nothing from your schedule.

What the free tools do not do

The free tools show what's in your schedule file. They work on one file, or one pair of files, at a time. They keep no history of your updates.

These come with Pathizer Enterprise:

Comparing every update in your project's history
Measuring delay and recovery from one update to the next
The Health Score
Drafted narratives

Questions

Do I need an account?: No. None of the four tools asks you to sign in. None of them needs a card.
Which file types do they take?: P7 opens .XER and .XML files, and exports .XER files. The Schedule Viewer opens .XER, .XML, Microsoft Project .xml and SDEF files. The Health Check and Update Compare open .XER files. The Viewer, Health Check and Update Compare take files up to 20 MB.
Is my schedule sent to Pathizer?: No. Your files are opened in your browser and never uploaded. Pathizer does get a few short notes: the Health Check and Update Compare steps, and the one P7 note if you allowed ad cookies. None of them has anything from your schedule.
