Patens

Patens is a design tool for designing beautiful typefaces — with some assistance.

One unbroken take in the editor: draw a lowercase a , trace it to Béziers, let the audit read the result, apply a one-click fix, kern the new letter against V , and export an OTF you could install right now. No cuts, no speed-ups.

Studio Geometric — drawn in Patens, exported by Patens, shipped as the editor's demo OTF. It's not a marketing typeface; it's the kind of work the editor produces end to end, from a blank canvas to an installable file.

Patens runs all 105 rules continuously. When a contour crosses itself, when an x-height drifts, when a sidebearing wanders from its class — the audit notes it in plain English, beside the glyph, while you draw. Around 30 codes also offer a one-click fix; the rest are matters of judgment.
