AI Plan Review

Built so the professional stays in control.

When Mason spots a code issue, it shows you its reasoning so you can weigh the evidence, apply your expertise, and own the decision.

Watch it work through a real plan set in about the time it takes to make a coffee.

Built for the Review

Four features that change how your team works.

Designed around how plan reviewers actually spend their day. Not how someone guessed they might.

Feature 01 - Interface

The items that matter most are always at the top.

  • Code failures rise to the top of the panel automatically. Your reviewer sees what needs attention before anything else.
  • Passed items and non-applicable checks stay out of the way behind a toggle so the screen stays clean during the review.
  • Every check carries a clear status indicator so the full picture is readable in seconds without digging.
  • Everything Mason ran is still there. The sort order changes so reviewers spend less time navigating and more time deciding.

Feature 02 - Comment Letter

A working draft letter waiting before the reviewer opens the file.

  • Mason prepares around sixteen comments per letter across the full code scope before your team reads a single line.
  • The draft arrives in the same format your office already uses so there is no reformatting step before it becomes useful.
  • Reviewers spend their time refining good work rather than building a letter from scratch.
  • Every comment is yours to accept, change, move around, or remove. Mason prepares the draft and you own the result.

Feature 03 - Code References

The code is always one click away. Never two screens.

  • Every flagged item links directly to the section it cites. Reviewers jump straight there without hunting through a separate document.
  • The full code library lives inside Mason so your team stays in one place from start to finish.
  • Verify or challenge any AI finding right on the same screen where you are already working.
  • Putting the authoritative source within reach of every decision is central to how Mason keeps humans in charge.

Feature 04 - Authoring

A few keystrokes. A complete comment with citation.

  • Typing a partial code term brings up matching sections and a ready-to-use comment draft in the same motion.
  • The citation attaches automatically so reviewers never have to go look up a section number to finish a comment.
  • With the code book embedded, your team writes the whole letter without leaving Mason to confirm anything.
  • Every suggested comment is editable down to the word before it goes into the letter. The language stays yours.

No new process. Just a smarter first pass.

01

01 · Get the Plans into Mason

Drop the permit set into Mason, then run your own pass in Bluebeam or whatever markup tool your team uses. Mark what looks suspect before you touch Mason's output. Starting with your own read means the review you do afterward is grounded in what you already know about this project.

02

02 · Work Through Mason's Checklist

Mason sorts its findings so the most critical items sit at the top. Click to add any comment where the logic holds up. When you disagree with a finding, override it. That correction feeds back into how Mason handles similar situations going forward.

03

03 · Close the Gap with Your Own Markups

Compare what you caught against what Mason flagged. Anything that made it into your markup but not into Mason's checklist belongs in the letter. You shape the final product. Mason handles the groundwork and stays out of your way when it counts.

04

04 · Draft, Refine, and Send

As you type, autocomplete surfaces relevant code citations and drops them directly into your comment. When everything looks right, export the letter to Word. On an enterprise plan, you can push directly into whatever format your jurisdiction requires.
