Drawing review, accelerated

A second
pair of eyes
on every drawing.

Upload a floor plan. AI catches code issues before your reviewer does — so drawings ship faster, your code consultant has less to fix, and nothing comes back as a surprise at permit stage.

Three layers.
One faster turnaround.

From raw drawing to a head-start report, every step is traceable, repeatable, and auditable. Your code consultant picks up where the AI left off — faster.

Reads your drawing like a senior reviewer

Upload any floor plan — PDF, PNG, DWG, DXF, or IFC. Claude Vision spots dimensions, materials, room labels, egress geometry — the way a senior reviewer would. You confirm what it found, then rules run on what you confirmed.

Catches issues your reviewer would

97 published-code checks across 10 domains run on every drawing — egress capacity, accessibility, fire ratings, carbon intensity, code geometry. Issues surface in minutes, not at permit stage. Every verdict is traceable to a cited public standard.

IBC, ADA, ASHRAE, LETI, FEMA, ANSI citations

A head start on the fixes

Every review is saved. Ask the AI why an issue flagged, what code section applies, or what change would clear it. Full history, exportable reports your code consultant can pick up where you left off.

The only compliance engine with auditable, inspectable rules.

Other tools use black-box AI to guess at compliance. CRE runs every check against a transparent rule engine — every threshold cites a published standard, every verdict is traceable, and every rule is open for your team to inspect, override, or extend.

Every rule cites IBC, ADA, ASHRAE, LETI, or peer-reviewed research
Open rule schema — read, override, or write your own
No black-box verdicts — full audit trail from drawing to sign-off

From drawing
to head-start.

No integrations. No setup. Upload once — get a pre-review report with every issue flagged before your reviewer sees them.

Drop in your drawing

Any architectural drawing — PDF, PNG, DWG, DXF, IFC. AI Vision pulls parameters from the file directly: wall assemblies, egress paths, door widths, room areas, stair geometry. No manual data entry to start.

Verify what the AI read

Every value the AI extracts is editable. Fix anything wrong before rules run — corrections are tracked in the audit trail. You sign off on the inputs, not the AI. No silent assumptions, no rubber-stamping.

Get your pre-review report

97 published-code checks across 10 domains run instantly. PASS, FAIL, WARN, or NEEDS-DATA — each with the specific code citation and a plain-English explanation. Ask the AI for fixes — your code consultant picks up where you left off, faster than starting from scratch.
