A modern web-based BCF (Building Collaboration Format) platform with universal format support, analytics dashboard, viewpoint coordinate extraction, and professional reporting capabilities.
BCFSleuth V2.0 is what happens when real-world AECO/BIM experience meets AI coding horsepower:
- 🧠 AI Assistant: Claude (Anthropic) helped with architecture ideas, cranked out code, and tracked down bugs
- ⚡ Fast Build: Features that would've taken months the old way came together in days
- 🏗️ Domain Expertise: 25+ years in AECO/BIM guiding the direction and keeping it practical
- 🔄 Iterative Workflow: Build, test, tweak, repeat — until it was rock-solid and ready to use
The result? A capable, ready-to-work BCF management platform built faster than I thought possible
BCFSleuth is a modern, web-based evolution of BCF management tools like the original Sloth. It processes BCF files entirely in your browser - no uploads, no accounts, complete privacy. Drag in your BCF files and get instant access to data analysis, image management, viewpoint coordinate extraction, and professional reports.
Universal BCF Support: Handles all BCF formats (2.0, 2.1, 3.0) with intelligent format detection and adaptation.
