Engineers
AI that understands your engineering documents.
Catch conflicts, extract requirements, and review technical drawings faster than any manual workflow.
AI plan review — an extra QC pass before drawings go out
Six AI models — Gemini, GPT, Claude, Kimi, Qwen, and DeepSeek — run alongside deterministic rules and cross-reference audits, consolidated into one findings dashboard. Results group by sheet with severity labels; verify each one against the drawing, apply markups to the PDF, and export the report for the QC record.
- Flags missing design-load, seismic, and risk-category criteria before issue
- Cross-reference audit catches callouts to sheets that aren’t in the set
- Critical / major / moderate / minor counts set the triage order
- Failed model runs shown honestly — a skipped check is not a clean pass
- Every finding is a candidate to verify, not a verdict — judgment stays with the engineer
Take the Free Plan Review Challenge
Email a real drawing set to support@pdfdepth.com. We'll run PDFDepth's AI engineering plan review on it and send back the comments and markups it produced — see what it catches on your own drawings, then try it yourself free.
