CSci Diff GT
A specialist application that finds and highlights all differences between two technical PDF documents, optimized for CAD drawings and circuit diagrams.

This desktop tool compares two PDF versions and visually marks additions, deletions and modifications across text, vector graphics and raster content, making it easier to verify revisions in complex technical documents.

The interface is designed for quick results: drag-and-drop files, automatic page pairing for documents with different page counts, synchronized zoom views and color-coded markers for fast inspection. Results can be exported as a human-readable PDF report or as XML for automated workflows.

Technically, the solution combines pixel-accurate image comparison with tolerant text comparison to avoid false positives caused by layout or font changes. It runs natively on modern 64-bit Windows and macOS systems, uses parallel processing for performance, and is offered as an on-premises tool (no cloud required), aimed at industries from electronics and mechanical engineering to architecture and construction.
