Why Cortex Digital Hub
Most free online tools work by uploading your file to a server, processing it there, and sending it back. That means your floor plans, photos, ID scans and contracts sit on someone else's computer. Cortex Digital Hub takes a different route: every tool here is built to run inside your browser, so the file never leaves your device. Close the tab and nothing remains.
The site started with one problem: turning a flat 2D floor plan into a clear, furnished 3D view that buyers can actually understand. From there it grew into a set of everyday tools for images, PDFs and video, built the same way: fast, free and private.
