Intelligent Comparison
The Compare module brings visual intelligence to revision tracking. Overlay drawings with AI-powered sheet matching, detect changes in specifications, and track document evolution across your entire project lifecycle.
Two Powerful Compare Modes
Whether you're comparing CAD drawings or contract revisions, the Compare module adapts its intelligence to deliver the insights you need.
Drawing Overlay Compare
Visually compare revisions of architectural and engineering drawings with intelligent overlay technology.
AI Sheet Matching
Automatically identify and match corresponding sheets across revisions—even with different naming conventions.
Smart Auto-Alignment
Neural alignment that handles scale differences, rotations, and partial overlaps for pixel-perfect comparison.
Change Detection
Highlight additions, deletions, and modifications with color-coded overlays and change summaries.
Document Revision Compare
Track changes across specifications, contracts, and other text-heavy documents with semantic understanding.
Spec Comparison
Identify changes in specifications including updated requirements, deleted sections, and modified parameters.
Contract Tracking
Track legal and contractual changes with emphasis on scope modifications and term updates.
Semantic Diff
Go beyond text matching—understand the meaning of changes and their impact on the project.
See Changes Instantly
Toggle between revisions or overlay them to spot every modification at a glance.
