Welcome to LignumAI
From lines to meaning — instantly.
LignumAI transforms architectural, engineering, and construction drawings into structured, machine-readable intelligence — enabling automation, insights, and next-generation workflows.
about us
Your partner in AI-powered technical drawing intelligence
LignumAI converts legacy construction and engineering documents into modern, machine-readable data. We enable automation, accelerate project workflows, and help companies unlock insights hidden inside unstructured drawings.
Automated drawing comprehension
AI models designed to read, interpret, and structure plans, blueprints, and schematics for seamless digital workflows.
our solution
Intelligent tools built for construction & engineering data
AI that identifies symbols, annotations, layers, materials, and relationships inside technical drawings.
Detect equipment, walls, doors, beams, symbols, and components inside plans with high accuracy.
Convert PDFs and DWGs into structured, searchable datasets ready for BIM, ERP, and digital workflows.
Extract lengths, areas, counts, and quantities automatically from plans — no manual tracing required.
Seamlessly connect to existing systems including BIM tools, ERP platforms, and project management apps.
Custom training on your organization’s drawings, standards, and symbol libraries.
35+
Years of experience in project documentation and technical drawing
our capabilities
Turning technical drawings into operational intelligence
Real-time comprehension
Process drawings instantly and surface structured information in seconds.
Multi-discipline support
Architecture, MEP, structural, civil engineering — one model for all formats.
Continuous learning
Your model improves over time by learning from your standards and project history.
how it works
Turning complex drawings into structured, usable data
automated drawing understanding
LignumAI analyzes architectural, engineering, and construction drawings to recognize symbols, layers, annotations, and relationships — without manual tracing or redrawing.
clean, structured output
We transform unstructured PDFs, scans, and CAD exports into organized data that can feed BIM tools, project controls, ERP systems, and analytics dashboards.
connect to your existing tools
LignumAI integrates with your current ecosystem — from BIM and document management platforms to custom APIs — so your teams can keep working in the tools they already know.
Faster project onboarding
Extract key information from drawings in minutes instead of doing it manually, getting new projects up and running faster.
Search across legacy plans
Turn decades of archived drawings into searchable, analyzable data instead of leaving them locked away in folders.
Data you can automate on
Structured outputs feed automation, reporting, quality checks, and AI copilots built on top of your drawings, helping teams work smarter and faster.
