Files, images, and document-shaped content.
6 detectors
Time & Location
Timestamps, dates, and GPS coordinates — anything that pins down when or where.
3 detectors
Measurements
Values with units — temperatures, distances, weights, paces, and conversions to standard peers.
1 detectors
Design
CSS values, SVG, and other artifacts you'll see while designing.
