How matching works
- The canvas is sampled for ink density, bounding-box aspect (width), row-centroid slope (slant), edge roughness (softness), and local ink radius (stroke weight).
- Those axes are compared to a curated catalog of Google Fonts with hand-tagged weight, width, contrast, serif presence, and mood.
- Your text query and chips expand through a small alias map and boost tag hits.
This is not a neural net. It is a very opinionated ruler — fast, private, and good enough to start a real type decision.
