AXIOLITH REDLINE · v1.1 · Local-first drawing & spec review

Redline your set before the plan checker does.

AXIOLITH REDLINE runs eighteen cross-discipline coordination and specification checks on a permit set and hands back two annotated PDFs. It installs on your Windows workstation. Your drawings are processed on your machine — the only thing that goes online is a periodic license check. Your originals are never modified.

The night before submission

In a small firm, the QA/QC department is you.

Most architecture practices are one to three people. There is no coordination team, no spec reviewer, no second set of eyes — there is the principal, the night before the set goes out, reading structural against architectural one more time.

When something slips through, the correction cycle costs weeks of schedule and redraw hours a fixed-fee client will never pay for. The cross-check that would have caught it is two days of junior-associate work that most small firms don't have a junior associate for.

74%

of architectural businesses are sole practitioners or have fewer than three architectural staff (AIA)

How it works

Point it at a folder. Get two PDFs back.

Step 1

Point it at a folder

One folder with the drawing set and the specification book. AXIOLITH finds every PDF inside it, tells drawings from specs, and indexes the text of each sheet and section.

Step 2

Run the reviews

Eighteen one-click checks, or all of them at once. A live monitor shows which discipline pair is being reviewed and which source is being read.

Step 3

Open the results

A Consolidated Drawing Review PDF and a Consolidated Spec Review PDF, with evidence-linked notes down the right edge of each page, plus a run summary. Your source files are untouched — the outputs are new copies.

A permit set and a spec book go in. The Consolidated Drawing Review and Consolidated Spec Review come out, with every note pointing at the sheet and text it came from.

What you get back

Every note says where it came from.

Each finding carries an ID, the disciplines involved, the source text and page it was drawn from, a classification, a confidence level, a recommendation, and a flag if it looks like an RFI. Findings are tracked for human review — you mark what's real.

High

Language on one sheet that reads as a conflict, clash or interference with another. Your call whether it is.

Coordination

Clearances, openings and penetrations that need two disciplines to agree.

Potential

A signal worth a look at the source before you decide.

No Signal

The review ran and found nothing to say. This is a run result, not an all-clear.

Needs Context

Your own note: a missing detail or installer requirement the set does not answer yet.

Local-first

Your drawings never leave your desk.

Installs on your workstation

A Windows installer puts the application and the local model on your own machine. It checks your hardware and disk space first. No external drive required.

Documents never uploaded

Project files stay where they are. Nothing about your drawings, specifications or prompts is sent anywhere. The only thing that goes online is a periodic license check.

Originals stay original

Reviews write new annotated copies. Your source PDFs are read, never changed.

A local model, on your machine

General questions get answered by a language model that runs on your own hardware — not a service.

You own the output

Standard PDFs. Open them in Bluebeam Revu, Acrobat, or anything else that reads a PDF.

Human in the loop

It flags, cites and recommends. You decide what's real, and the stamp stays yours.

Who built it

Made by an architect who produces permit sets.

AXIOLITH REDLINE started as an in-house tool for one small practice in Denver — a way to run the cross-checks a larger office would hand to a junior, without a junior to hand them to. It runs on every set that practice submits. It is being offered to other firms of one to five because they carry the same load with the same headcount.

"An hour of my time now runs the two days of cross-checking I never had anyone to give it to."

Questions

Straight answers.

Is this a code check or a compliance review?

No. AXIOLITH REDLINE is a quality-assurance aid. It flags, cites and recommends; it does not determine compliance, approve anything, or replace your judgment. The architect of record remains responsible for the set.

Does it detect clashes like a BIM model would?

No. It reads and cross-references the text of your drawings and specifications — callouts, notes, schedules, sections. It does not model geometry. That is why it runs on an ordinary Windows workstation.

Does it work on scanned sets?

It reads the text layer of a PDF. Pages that have no text layer aren't reviewed. Sets plotted from Revit or AutoCAD with proper title blocks work best.

Do I need Bluebeam?

No. The outputs are standard PDFs with standard notes. Open them in Revu, Acrobat, or any viewer.

What do I need to run it?

A Windows PC. The installer checks your hardware and disk space, then sets up the application and the local model. Real sets take real time — a full run on a large set is a coffee break, not a click.

Will my drawings be uploaded anywhere?

No. Reviews run on your machine. The app verifies its license online periodically — that check carries your license and a device ID, never your drawings, specifications or prompts. Updates and the initial model download need a connection.
