VellumDrop
The Blueprint for Enterprise Architecture
VellumDrop provides the modern infrastructure for elite architectural firms to organize projects, collaborate on blueprints, and harness AI-driven insights securely.
Intelligent Analysis for Construction Documents
VellumDrop's proprietary AI doesn't just "see" pixels—it understands the architectural intent of your drawing sets. Our engine transforms flat PDFs into a living, interconnected database of project data.
Automated Callout Hyperlinking
Instantly turn detail bubbles, section cuts, and elevation markers into live links. Navigate from a floor plan to a wall section in a single click.
Intelligent Revision Propagation
When an addendum or revision is issued, VellumDrop automatically stacks the new sheet and carries forward all annotations, RFIs, and measurements from previous versions.
Automated Sheet Indexing
High-fidelity OCR extracts sheet numbers, titles, and revision dates from title blocks with 99.9% accuracy, automatically organizing your entire drawing package.
Built for the demands of the modern firm
A seamless, high-performance experience designed to bring your team and your plans together.
GPU-Accelerated Loads
VellumDrop converts heavy Construction Documents into optimized assets that leverage hardware acceleration for instant, fluid panning and zooming on drawings of any scale.
True Offline Sync
Maintain access on the job site with zero connectivity. VellumDrop's robust offline mode lets you view plans, add annotations, and sync automatically when you reconnect.
Integrated RFIs
Streamline communication by managing Requests for Information directly on your plans. Link queries to specific callouts and resolve field ambiguities faster.
Document Versioning
Maintain a complete audit trail of every blueprint iteration. Instantly switch between versions to track project evolution throughout the construction lifecycle.
Intelligent Diffing
Visually compare two revisions with pixel-perfect accuracy. Our alignment engine detects changes even if the floorplan was shifted on the new sheet.
Auto-Calibrated Measuring
VellumDrop automatically detects the scale from the title block. Say goodbye to manual calibration—just point and click to perform accurate takeoffs instantly.
AI Photo Tagging
Computer Vision analyzes site photos automatically, generating semantic tags and linking images to specific architectural components for effortless retrieval.
Universal Ecosystem
Work where you are. VellumDrop runs flawlessly on web, iOS, and Android, keeping your projects in perfect synchronization across the office and the field.
Enterprise-grade Intelligence.
VellumDrop isn't just a viewer. It's powered by a dedicated intelligence microservice running advanced OCR and deep learning models to handle heavy processing asynchronously.
