# Mason AI

> Mason AI is AI-powered plan review and plan check software for private plan reviewers, plans examiners, and plan checkers.

Mason AI is built by a team of AI engineers focused on building code compliance. It is tuned for real plan review workflows — residential, learning/training, and quality assurance — and provides building code citations for every flag so reviewers can trust and verify the output.
