GridSnag-Field Snag & CAD Grid

GridSnag is the next-generation, 100% offline field inspection and punch list system built natively for semiconductor fabs, cleanroom facilities, MEP contractors, and critical public infrastructure. Designed specifically for secure industrial facilities where cameras and sensitive drawings are restricted from the cloud, GridSnag runs entirely on-device with Zero Cloud Egress. Combine ultra-high-definition vector CAD plans, automatic column grid snapping, on-device voice dictation AI, and regulatory digital blackboards in one seamless native Apple workflow. KEY CAPABILITIES: 1. Zero Cloud Egress & 100% Offline Security • No servers, no tracking, and no external API dependencies. • All drawings, punch pins, voice transcripts, and photos are safely stored in Apple's encrypted local sandbox. • Fully operational in RF-shielded cleanrooms and underground structures without network or cellular reception. 2. Vector CAD Plans & 1000% Lossless Zoom • Powered by native PDFKit vector rendering, zoom up to 1000% without loss of detail. Inspect micro-valves, conduit lines, and ductwork markers with sub-millimeter precision. • Tap anywhere on architectural or MEP drawings to instantly lock and snap to the nearest structural column lines (e.g., Grid P22-P23 / RB-RC). • Includes an Interactive Structural Grid mode for blueprint-free field inspections. 3. Hands-Free On-Device Voice AI Structuring • Powered by WhisperKit and local Core ML neural processing. • Walk the jobsite and speak naturally: "Firestopping thickness between columns P22-P23 is inadequate. Critical defect, notify Tatung Fire Engineering to rectify by Friday." • The on-device AI automatically categorizes discipline, defect severity, assigned subcontractor, and remediation deadlines. 4. Regulatory Digital Blackboard Watermarking • Capture site inspection photos with an auto-burned regulatory blackboard directly on the bottom-right corner. • Permanently embeds project title, column coordinates, inspection items, inspector sign-off, and tamper-proof SHA-256 digital stamp into the photo pixels. • Built-in specialized audit templates for Firestopping Sealant Depth (ASTM E814 / UL 1479) and Hot Work / Fall Protection safety checklists. 5. One-Tap Official Audit PDF Reports • Generate comprehensive, publication-ready punch list audit reports directly on your device. • Includes blueprint locator thumbnail indexes, watermarked defect photos, and digital sign-off blocks. • Instantly hand off reports on site via Apple AirDrop, USB flash drive, or secure local file export.
