How the two tools could sit next to each other.

Intake stays clean.

Use a pre-check tool to filter incomplete submissions before they reach a reviewer.

Substance gets reviewed.

Once the permit set is complete, the plans examiner reviews the plans with Mason.

Two tools, one outcome.

A complete permit set that meets the code, delivered faster than either tool can produce alone.

See It On Your Plans

The fastest way to understand the gap is to run both on the same permit set.

Bring a plan your team has already reviewed. Watch Mason draft the comment letter while the pre-check tool flags a mistaken sheet index. Compare side by side.
