MYLAR
Upload construction blueprints and get instant MEP material counts. AI that reads mechanical drawings so you don't have to.
How Mylar Works
From blueprint PDF to material list. Every step automated, every symbol counted.
Upload Blueprints
Drag and drop construction PDFs up to 200MB. Mylar automatically splits pages, strips title blocks, and prepares every sheet for AI analysis.
- PDF upload with auto page splitting
- Title block and schedule removal
- Instant thumbnail generation
- Multi-project organization
AI Symbol Detection
Our YOLO-based model scans every page tile-by-tile and identifies 34 classes of HVAC symbols with bounding-box precision and confidence scoring.
- 34 HVAC symbol classes
- Sliding-window tile inference
- NMS stitching across tiles
- Per-detection confidence scores
Material Counts
Every detected symbol is categorized and counted automatically. Export your complete material takeoff as CSV or view the annotated overlay.
- Categorized count by class
- CSV export for estimating
- Per-page breakdown
- Annotated overlay image
Blueprint Overlay
View your original blueprint with color-coded detection boxes drawn on top. Each symbol type gets a unique color for instant visual verification.
- Color-coded bounding boxes
- Class labels on each detection
- Full-resolution overlay PNG
- Zoom and pan support
Multi-Tenant Platform
Each contractor gets their own workspace with projects, uploads, and usage tracking. Admin tools for invite codes and team management.
- Invite-only onboarding
- Per-tenant usage limits
- Project-based organization
- Role-based access control
Custom Models
Every contractor draws differently. Mylar supports per-tenant model selection — use the global baseline or a model fine-tuned on your drawing style.
- Global baseline model
- Drawing-style baselines
- Per-tenant custom models
- One-click model switching
Trained on real construction drawings. Every symbol maps directly to an estimate line item.
