Doodle Fonts fixes that. It's a font foundry that fits inside a canvas. You draw each glyph — freehand pencil, shapes, a dot grid, whatever feels right — across a full 96-character set covering upper, lower, numbers and punctuation. The whole alphabet renders live as you go, every font is saved to a library with an "X / 96 drawn" progress count, and when you're done you export a real, working, installable OTF font file.
