Comparison

Mason vs AI Chatbots

A chatbot will answer a code question. Mason reviews the plan set itself. One is a conversation, the other is a draft comment letter.

Side By Side

Where the difference shows up.

Chatbots are general tools. Mason is a plan review tool. Here is what changes when the work moves from a conversation window to a permit set.

Where Mason Differs

Three things Mason does that chatbots do not.

General chatbots are useful for plenty of work. Plan review is not where they win.

Works on the Permit Set

Chatbots cannot ingest a multi-sheet PDF and review it page by page. Mason is built around that exact workflow.

Cites the Code Section

Every Mason comment is linked to a specific section of the California code. Reviewers verify the citation in the embedded code book without leaving the screen.

Produces a Comment Letter

Chatbots produce conversation. Mason produces a draft comment letter in your office format, with each comment ready to accept, edit, or remove.

Why It Matters

What this looks like in your day.

What changes when the tool is built for the actual review work.

01

One workflow, not two.

Reviewers do not pivot between a code book, a chatbot, and a comment letter. Mason puts the code, the plan, and the draft in one screen.

02

Every comment is sourced.

Comments arrive with the code citation attached. Reviewers verify the source on the same screen instead of trusting an unsourced answer.

03

Built for the format reviewers ship.

The output is a comment letter your office already uses. No reformatting step, no copy paste from a chat window.

See It On Your Plans

A chatbot will explain a code section. Mason reviews the actual plan against it.

Bring a permit set and try both. One gives you a conversation. The other gives you a draft comment letter with the code citations already in place.
