About PathProof

PathProof reads Microsoft Project or Primavera P6 schedules and performs automated compliance checks, risk analysis, and update comparisons without uploading files. It runs the DCMA 14-point assessment, Monte Carlo simulations for probabilistic finish dates, and update-to-update comparisons that highlight every change between schedule versions. The tool also checks update integrity for common errors such as out-of-sequence progress or actuals recorded after the status date. An AI assistant allows users to ask plain-language questions about logic chains, milestone movements, or delay drivers, with answers citing specific data points. All analysis executes locally on the user’s machine, and results can be exported to Excel or PDF for governance reviews. The application targets professional schedulers and project controls teams who need to validate schedule quality and detect risks before reporting to stakeholders.

Frequently asked questions about PathProof

What is PathProof and what does it do?

PathProof is a desktop application that reads Microsoft Project or Primavera P6 schedules and performs automated compliance checks, risk analysis, and update comparisons without uploading files. It runs the DCMA 14-point assessment, Monte Carlo simulations for probabilistic finish dates, and update-to-update comparisons to highlight changes between schedule versions.

Who should use PathProof?

The tool targets professional schedulers and project controls teams who need to validate schedule quality, detect risks, and ensure update integrity before reporting to stakeholders.

Does PathProof require an internet connection or file uploads?

No, all analysis executes locally on the user’s machine, and the schedule never leaves the user’s device. No file uploads or cloud processing are required.

How does the AI Schedule Assistant work in PathProof?

The AI assistant allows users to ask plain-language questions about logic chains, milestone movements, or delay drivers. It cites specific data points and uses the user’s own Anthropic or OpenAI API key, though the assistant is optional and all analysis can run without it.

What types of reports can PathProof generate?

PathProof can export audit-ready reports to Excel or PDF, including schedule quality scores, risk forecasting results, update-to-update comparisons, and update integrity checks formatted for governance reviews.

How do I get started with PathProof?

Download the application for Windows or Mac, install it without admin rights, and drop in your Microsoft Project or Primavera P6 schedule file. A free 7-day trial is available, followed by a free beta registration with an email address.
